Triterpenoid Saponins Investigation and Pharmacological (Cytotoxic and Antioxidant) Properties of Bacopa monnieri L. Cultivated in Iraq
...Show More Authors

Bacopa monnieri L. (Scrophulariaceae), synoname is Herpestis monniera that provides bioactive compounds, especially triterpenoid saponins (Bacosides) which exhibits an important biological activities, like hypothyroidism, anticonvulsant, memory enhancing and antistress. Because there are no researches about B. monnieri L. plant that grow in Iraq, and there active compounds especially triterpenoid saponin (TS), and there effects. This study was detected the presence of (TS) in, and examined the cytotoxic and the antioxidant activity of these compounds in vitro. The study was included the extraction and identification of TS from the whole parts of B. monnieri L. by using three methods, and the best yield was analyzed by High Performance Liquid Chromatographic (HPLC) to identify bacosides compounds. In vitro, TS was examined the cytotoxic activity against two cancer cell lines, human cervical cancer (Hela), rhabdomyo sarcoma (RD), and rat embryogenic fibroblast (REF) as a normal cell, at concentrations of 62.5, 125, 250, 500 and 1000 ?g/ml at 24, 48, and 72-hr. Free radical 1,1Dyphenyl-2-picrylhydrazyl radical (DPPH) was used for testing the ability of the TS as antioxidant at 20, 40, 60, 80, 100 ?g/ml concentrations. The results revealed that B. monnieri plant had many components of bacosides when detected by HPLC. Cytotoxic study suggested that TS inhibited the growth of cancer cells, and this effect is depending on the extraction of TS concentration. The effect of TS on Hela cell line was more than that for RD, while the highest effect of TS on Hela was at the concentration of 250 ?g/ml after 48 hr. The cytotoxic effect has a significant effect at (P?0.05). The results revealed that TS has high antioxidant influence 99.37% at 100 ?g/ml concentrations, followed by 98.20% in 80 ?g/ml concentration.

Bayes Classification and Entropy Discretization of Large Datasets using Multi-Resolution Data Aggregation
...Show More Authors

Big data analysis has important applications in many areas such as sensor networks and connected healthcare. High volume and velocity of big data bring many challenges to data analysis. One possible solution is to summarize the data and provides a manageable data structure to hold a scalable summarization of data for efficient and effective analysis. This research extends our previous work on developing an effective technique to create, organize, access, and maintain summarization of big data and develops algorithms for Bayes classification and entropy discretization of large data sets using the multi-resolution data summarization structure. Bayes classification and data discretization play essential roles in many learning algorithms such a

Comparison Study between Iraqi Conditions of Contract and FIDIC Conditions- The Red Book
...Show More Authors

Reconstruction in Iraq requires coherent legitimate frameworks that are able to detail obligations, rights and responsibilities of the parties participating in reconstruction projects, regardless their type or delivery system.
Conditions of Contract can be considered an important component of these frameworks. This paper investigates flexibility and appropriateness of the application of Iraqi conditions of contract in reconstruction projects. These conditions were compared to FIDIC Conditions. The objective wasn't comparing individual clauses, but rather exploring the principles and philosophy laying behind each conditions, and to what extent each conditions care about realizing equity between main contract parties. Validity of applic

Attitude and Altitude Control of Quadrotor Carrying a Suspended Payload using Genetic Algorithm
...Show More Authors

The need for quick airborne transportation is critical, especially in emergencies. Drones with suspended payloads might be used to accomplish quick airborne transportation. Due to the environment or the drone's motion, the slung load may oscillate and lead the drone to fall. The altitude and attitude controls are the backbones of the drone's stability, and they must be adequately designed. Because of their symmetrical and simple structure, quadrotor helicopters are one of the most popular drone classes. In this work, a genetic algorithm with two weighted terms fitness function is used to adjust a Proportional-Integral-Derivative (PID) controller to compensate for the altitude and attitude controllers in a quadrotor drone

HYDRODESULFURIZATION OF THIOPHENE OVER COMO/ AL2O3 CATALYST USING FIXED- AND FLUIDIZED-BED REACTORS
...Show More Authors

The present work reports a direct experimental comparison of the catalytic hydrodesulfurization of
thiophene over Co-Mo/Al2O3 in fixed- and fluidized-bed reactors under the same conditions. An
experimental pilot plant scale was constructed in the laboratories of chemical engineering department,
Baghdad University; fixed-bed unit (2.54 cm diameter, and 60cm length) and fluidized-bed unit (diameter of 2.54 cm and 40 cm long with a separation zone of 30 cm long and 12.7 cm diameter). The affecting
variables studied in the two systems were reaction temperature of (308 – 460) oC, Liquid hourly space
velocity of (2 – 5) hr-1, and catalyst particle size of (0.075-0.5) mm. It was found in both operations that the

Post-fire serviceability and residual strength of composite post-tensioned concrete T-beams
...Show More Authors
Abstract<p>In this study, the response of ten composite post-tensioned concrete beams topped by a reinforced concrete deck with adequate reinforcing shear connectors is investigated. Depending on the concrete compressive strength of the deck slab (20, 30, and 40 MPa), beams are grouped into three categories. Seven of these beams are exposed to a fire attack of 700 and 800 °C temperature simultaneously with or without the presence of a uniformly distributed sustained static loading. After cooling back to ambient temperature, these composite beams are loaded up to failure, using a force control module, by monotonic static loading in a four-point-bending setup with two symmetrical concentrated loads applied in </p> ...

Schema Theory and Text- worlds: A Cognitive Stylistic Analysis of Selected Literary Texts
...Show More Authors

Cognitive stylistics also well-known as cognitive poetics is a cognitive approach to language. This study aims at examining literary language by showing how Schema Theory and Text World Theory can be useful in the interpretation of literary texts. Further, the study attempts to uncover how readers can connect between the text world and the real world. Putting it differently, the study aims at showing how the interaction between ‘discourse world’ and ‘text world’. How readers can bring their own experience as well as their background knowledge to interact with the text and make interpretive connections.        Schema and text world theories are useful tools in cognitive stylistic studies. The reader's perception o

Inverse Kinematics Solution for Redundant Robot Manipulator using Combination of GA and NN
...Show More Authors

A demonstration of the inverse kinematics is a very complex problem for redundant robot manipulator. This paper presents the solution of inverse kinematics for one of redundant robots manipulator (three link robot) by combing of two intelligent algorithms GA (Genetic Algorithm) and NN (Neural Network). The inputs are position and orientation of three link robot. These inputs are entering to Back Propagation Neural Network (BPNN). The weights of BPNN are optimized using continuous GA. The (Mean Square Error) MSE is also computed between the estimated and desired outputs of joint angles. In this paper, the fitness function in GA is proposed. The sinwave and circular for three link robot end effecter and desired trajectories are simulated b
