Digitalization of mobile application in construction industry

Abstract. There is strong evidence that digitalisation offers the ability to improve or upsurge the productivity and change of information along the whole construction industry supply chain. The main purpose for this research project is to develop ways for the case company to connect its laser distance meters (LDMs) with an existing 3rd party app vendor or self-developed mobile applications to help penetrate the construction trades and respond to customer needs. The research project also represents the major pain-point of customers towards the use of existing mobile applications which support measuring in construction industries. It also aims at finding out whether measurement and data sharing in conventional methods are still used in the construction industry, and to explore the most relevant apps for each construction trade. To achieve the research objectives, key construction trade such as (Building Construction (BC), General contractors or Interior Finishing (IF), doors and windows industries or Steel Metal (SM), architecture metal and facade or Mechanical and Electrical (ME) were analysed constructed on the most relevant measuring application. Mobile apps used by construction professionals were clustered and assessed based on the correlation between app descriptions, price, rating, and popularity details from the App Store and the survey conducted and evaluated in their measuring functions. The results of this study lead to the fact that collaborating with key app developers will help to expand services and offering in the construction industry especially in the laser distance meter hardware. Due to that, it will be important to explore the existing trend towards mobile applications which support measuring applications in the construction industry

Anti-Arrhythmic Effect of Amiodarone Against Salbutamol and Aminophylline

Tachycardia refers to an abnormally fast resting heart rate. The higher-than-normal heartbeat means there is an increase in demand for oxygen by the myocardium (heart muscle) - if this persists it can lead to myocardial infarction. There are many causes to tachycardia, and one of them is the using of ant- asthmatic drugs like salbutamol and aminophylline which are well defined to cause tachycardia. This study Used the amiodaron to overcome tachycardia that associated with use of salbutamol and aminophylline. A group of 18 New Zealand rabbits were subdivided into 3 groups; first group (G1) was control, second group (G2) was salbutamol group, and the third group (G3) was aminophylline group. G2 and G3 received salbutamol and aminophylline respectively for one day, and then administered salbutamol plus amiodaron and aminophylline plus amiodaron respectively at another day, all the drugs were administered intravenously at dose (1mg\kg). The parameters are heart rate, respiratory rate and arterial oxygen tension which were measured in each group and after 15,30,60,90,120 minutes of administration. The results shows that when salbutamol and aminophylline used alone they caused increasing in heart rate and there was a highly significant difference (P<0.01) than normal. While the mixing of amiodarone with them, the heart rate was near to normal and there was non significant difference (P>0.05)

Study of effect of shear wall in the seismic response of the existing buildings

In Iraq, it has been observed that an increase in seismic activity, and that most existing buildings are not seismically designed and that can suffer serious damage or collapse, thus causing loss of life. In this paper, a numerical simulation of the experimental laboratory sample on the subject of non-seismically designed buildings and methods of strengthening them was performed using a seismic strengthening technique using an infill RC wall in order to maintain the risk of earthquakes. This study was carried out through the work of verifying the numerical and practical model by matching the results of laboratory work with the results of numerical analysis using the analysis finite element analysis method (FEAM) by Abaqus CAE 2019 software and then using the model to study the effect of openings in the infill RC walls and the extent of its impact on the response of the building. The practical model is a full four-story building tested laboratory in Elsa, Italy using pseudo dynamic test (PSD). The experimental model is a sample of not seismically design buildings (gravity design only) and ways to improve them by adding new RC walls with different contact details to the existing building. The goal of the experimental test was to study the effectiveness of adding RC infill walls with two types (North and South) infill RC walls, including designing it and the contribution of two types of dowels that connect the new infill walls to the existing RC building. In other words, it’s a way of strengthening by converting selected bays into RC walls with two types of reinforcement and connection between new infill RC walls and existing builders called (north and south) frames. The results of analytical modeling show that the percentage of differences in X- Direction of top story displacement between Abaqus software and Experimental tested at ELSA results are 2.47% in positive and 3.12% for negative X direction, which refer to a very good similarity and accurate building simulation

THE ANTI-CATARACT EFFECT OF COENZYME Q10 IN RABBITS

Objective: cataract is the opacity of the lens which progressively impairs the light transmission to the retina and finally prevents the vision, these opacity result from the oxidative process in the eye. The study aimed to prevent opacity of the lens by using Coenzyme Q10 as eye drops.Methods: Sodium selenite 0.01w/v injected intravitreal to the rabbit's eye to induce the disease, a group of rabbits were receive Coenzyme Q10 eye drop, and another group received distilled water, pre and post induction, cataract maturity was measured to evaluate the opacity deterioration.Results: the group of rabbits that received distilled water after induction of cataract, the opacity occurred within 48-72 h and the mean score of opacity reached to (4±0.00), while Coenzyme Q10 treated group the degree of opacity was (1.5±0.02), and there was a highly significant difference (p<0.01).Conclusion: Coenzyme q10 has an antioxidant activity when use as eye drops and this effect enable Coenzyme Q10 to prevent the opacity which is the major cause of cataract due to oxidative stress

Electron transport in double bridges system

In this paper we investigate theoretically the effect of introducing wide band, and Narrow band approximations for the bridge energy band on the electron transport process (ET) through the donor-bridges-acceptor (DBA) system. We using one electron model, for which the Hamiltonian of the system consists of a single-level for both Donor and Accepter (i.e. QD) both coupled to a band bridge as a tight binding interaction. The time dependent Schrödinger equation give us a formula for the occupation probabilities for donor and acceptor levels. The probability of (ET) to the donor and accepter is small because the electron accumulated on the bridge units. Also, the current of acceptor and the effect of different system parameters are studied

Molecular phylogenetic analysis of Enterobacter spp. isolated from urine of patients with cystitis in Babylon province, Iraq

Enterobacter species are important nosocomial pathogens responsible for various extraintestinal and intestinal infections. Both Enterobacter cloacae and Enterobacter aerogenes can cause hospital acquired and community acquired urinary tract infections. The aim of this study was to determine the phylogenetic analysis of Enterobacter spp. isolates. A total of 24 Enterobacter local isolates (9 isolates were E. cloacae (EC) and 15 isolates were E. aerogenes (EA) recovered from urine samples of patients with cystitis and subjected for PCR to determine the phylogenetic groups and subgroups by targeting two gene chuA, yjaA and anonymous DNA fragment TspE4.C2.The results found that the most isolates of Enterobacter spp. belong to the phylogeny group B2, 17(70.84%) and the largest subgroups was B23 (12/17) followed by subgroup B22 (5/17). The second phylogenetic group was group A, 4(16.66%) in which subgroup A0 compile (3/4) and A1(1/4). Group B1 compile 2(8.34%) followed by group D 1(4.16%). This study was the first to determine the phylogenetic groups of Enterobacter spp. isolates and demonstrate that these bacteria can be assigned to one of the main phylogenetic groups. Our results revealed that, Phylogenetic group B2(especially subgroup B23) was predominant among Enterobacter spp. isolates recovered from patients with cystitis

Graphene nanoplatelets suspended in different basefluids based solar collector: An experimental and analytical study

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. A flat plate solar collector (FPSC) was analytically studied, with functionalized graphene nanoplatelets (f-GNPs) as its working fluid. Four samples (wt % nanofluids) were prepared in different base fluids such as ethylene glycol (EG), distilled water (DW):EG (70:30), and DW:EG (50:50). Experimental results (via DW) were used to verify the effectiveness of the analytical model. Some of the operating conditions were taken into account in this research, including temperatures, power, and mass flow rates. Experimental techniques were used to elucidate the modified nanofluids’ physicochemical properties, such as its particle sizes, stability, and morphology, involving electron microscopes (EMs), UV–VIS, and X-ray techniques. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were applied to test the thermal analysis. The findings confirmed that the use of f-GNPs nanofluids enhanced the performance of the FPSC relative to the use of base fluids for all testing conditions. The maximum enhancement of the collector’s effectiveness at a mass flow rate of 1.5 kg min−1 and a weight concentration of 0.1 wt %, increased to 12.69%, 12.60%, and 12.62% in the case of EG, DW:EG (70:30), and DW:EG (50:50), respectively. The results also confirmed an improvement in both the heat gain (FR(τα)) and heat loss (FRUL) coefficients for the f-GNPs nanofluid

Vertical Stress Prediction for Zubair Oil Field/ Case Study

Predicting vertical stress was indeed useful for controlling geomechanical issues since it allowed for the computation of pore pressure for the formation and the classification of fault regimes. This study provides an in-depth observation of vertical stress prediction utilizing numerous approaches using the Techlog 2015 software. Gardner's method results in incorrect vertical stress values with a problem that this method doesn't start from the surface and instead relies only on sound log data. Whereas the Amoco, Wendt non-acoustic, Traugott, average technique simply needed density log as input and used a straight line as the observed density, this was incorrect for vertical computing stress. The results of these methods show that extrapolated density measurement used an average for the real density. The gradient of an extrapolated method is much better in shallow depth into the vertical stress calculations. The Miller density method had an excellent fit with the real density in deep depth. It has been crucial to calculate vertical stress for the past 40 years because calculating pore pressure and geomechanical building models have employed vertical stress as input. The strongest predictor of vertical stress may have been bulk density. According to these results, the miller and extrapolated techniques may be the best two methods for determining vertical stress. Still, the gradient of an extrapolated method is much more excellent in shallow depth than the miller method. Extrapolated density approach may produce satisfactory results for vertical stress, while miller values are lower than those obtained by extrapolating. This may be due to the poor gradient of this method at shallow depths. Gardner's approach incorrectly displays minimum values of about 4000 psi at great depths. While other methods provide numbers that are similar because these methods use constant bulk density values that start at the surface and continue to the desired depth, this is incorrect
