IgG and IgM cardiolipin and phospholipid antibodies were measured, by an ELISA technique, in the sera of patients with toxoplasmosis. Immunological methods for autoantibodies had been applied by ELISA. Regarding Anti-cardiolipin it was revealed that 24.7% of toxoplasmosis cases versus 0% of control group showed significant positive result (P=0.0412) . Whereas, 12.5% of toxoplasmosis patients and 12% of healthy controls had anti-cardiolipin antibodies, with no significant differences (P=0.554) between these two groups

Investigation in Gas-Oil Two-Phase Flow using a Differential Pressure Transducer and Wire Mesh Sensor in Vertical Pipes

The current study is performed to identify the flow regimes of oil-gas two-phase flow experimentally in a vertical pipe has an internal diameter of 6.7 cm. It also aims to provide more details about the possibility of using Differential Pressure Transducers (DPT) for indicating flow patterns. A flow development of oil and gas has been investigated in a vertical pipe of 6 m in length and operated at atmospheric pressure. A series of experiments have been run to cover a range of inlet oil superficial velocities from 0.262 to 0.419 m/s, and inlet gas superficial velocities from 0.05 to 4.7 m/s. Wire Mesh Sensors (WMS) have been used to collect the obtained void fraction values of the flow. The Differential Pressure Transducer (DPT) is utilized to measure the pressure drop values of a one-meter along the pipe. The flow patterns are classified according to the analysis of void fractions, pressure gradients regarding time series, tomographic images, probability density functions of the void fractions, and pressure gradients. A bubbly flow is observed at low superficial velocities of gas and liquid, slug flow is observed at the lower flow rate of liquid and moderate flow rates of gas, while the churn flow pattern is recognized at the higher rates of liquid and gas. Also, the result has revealed the possibility of using Differential Pressure Transducers (DPT) to classify the gas-oil flow patterns in vertical pipes

THE EFFECT OF USING RUBBER TIER AND GLASS WASTE ON THE PROPERTIES OF CEMENT MORTAR

This research studies the effect of rubber tier waste and waste glass together on the properties of cement mortar and used mixing ratio (1: 3) and has been added rubber tier waste ratio are (10%, 20%, and 30%). Has been added waste glass ratio are (10%, 20%and 30 %) and also added rubber tier waste and waste glass together ratio are (10%, 20% and 30%) by weight of the replacement of cement. This study includes mechanical properties such as compressive strength and physical properties such as water absorption, density and also setting time. The results obtained from the study that compressive strength decreases when increasing the percentage of additives of mortar .The water absorption increased when the percentage of additive is increased. The density decrease when both percentage of additive increase in mortar cement. Also, the setting time increases when the percentage of additive is increase

Experimental Investigation of Two-Phase Flow Patterns in a Vertical to Horizontal Bend Pipe Using Wire-Mesh Sensor

The air-water two-phase flow plays an important role in many applications of industry fields. Usually, a 90-degree bend is used to connect pipes for changing the direction of flow which influences the two-phase flow pattern. In this paper, the effect of 90-degree bend under different ranges of gas and liquid superficial velocities on the two-phase flow patterns in the horizontal pipe located after the bend was experimentally investigated, and then results were presented and compared in a two-phase flow pattern map. Also, tomographic images and probability density functions were used to capture the cross- section void fraction and its distribution for the two-phase flow patterns. The results revealed that at low liquid and gas flow rates, a stratified-wavy flow pattern was observed as a dominant flow pattern. While the wavy-annular and semiannular flow patterns were observed at a high range of gas flow rates in the horizontal pipe. The results also showed that at the high range of liquid flow rate, bubbly, plug, slug, stratified-wavy, and wavy-annular flow patterns were observed in the horizontal pipe when the gas flow increased. The tomographic images and probability density functions gave good agreement with the experimental observations and results

CFD Simulations and Experimental Observation for Air-Water Two-phase Flow in a Vertical Pipe

Air-water two-phase flow development in a vertical pipe has been investigated through service of experiments and simulations in this research. Differential Pressure Transducers (DPTs) and Wire Mesh sensors (WMSs) are used to monitor the two-phase flow in a vertical pipe of 67 mm inlet diameter and 7000 mm length. Computational Fluid Dynamic (CFD) is used to evaluate the experiments of the air-water flow in the vertical pipe using a volume of fluid (VOF) model. The operating conditions cover a range of inlet air superficial velocities from 0.05 to 5 m/s. The inlet water superficial velocity remains constant at 0.2m/s and 0.4 m/s for all experiments. The results show that the bubbly flow is noted at low superficial velocities of gas, slug flow is observed at the moderate flow rates of gas, while the churn flow pattern is observed at high rates of gas. There is no significant effect when the Usl changed from 0.2 m/s to 0.4 m/s on the vertical flow lines. Pressure drop is recorded and compared with the CFD simulations. The CFD results are over estimation compared with the experimental pressured drop with maximum absolute error of 21% at Usl of 0.2 m/s and 25% at Usl 0.4 m/s

Data Delivery Algorithm for Latency Sensitive IoT Application

Internet of things represents the third generation of the Internet that is expected to connect billions of heterogeneous devices in a smart way. This large number of connected devices puts high constraints on the system structure and design. In this paper we analyze the features of the IoT networking. The aim of this paper is the Internet of Things organization, as well as the modeling of the message delivery process in conditions of low density of users and in case of low mobile networks coverage. The target network is considered as a network with moving nodes that can perform the functions of data transporting between points with different geographic coordinates. A proposed system in this paper allows to implement an approach for building of such network. © 2019, Springer Nature Switzerland AG

Experimental comparison between wire mesh and electrical capacitance tomography sensors to predict a two-phase flow behaviour and patterns in inclined pipe

Two-phase flow behaviour and its flow patterns have a significant effect in many applications in industry. Oil-gas is one of the two-phase flow types that have many applications in petroleum and power stations. An oil-gas two-phase flow behaviour and flow patterns have been investigated in an inclined pipe using two different tomography sensors: Wire Mesh sensor (WMS) and Electrical Capacitance Tomography (ECT). A special experimental facility was designed and built to operate the tow-phase flow application in the inclined pipe with the various angle of inclination. A set of experimental data were collected using operating conditions which covered a two-phase flow range of superficial velocity of gas (Usl) from 0.05 to 0.52 m/s and superficial velocity of liquid (Usg) from 0.05 to 4.7 m/s at atmospheric pressure and room temperature. Three inclined angles to change the pipe’s inclination 45, 60, and 80-degree were applied in the experiments. The Comparison between the Wire Mesh Sensor (WMS) and Electrical Capacitance Tomography (ECT) was completed experimentally. The results revealed that there is a good agreement between the two sensors, however; the WMS had a higher frequency which was calculated 1000 frames per second compared with the ECT which worked at 200 frames per second
