The olive tree, has been used it is important plant for the time being some of their parts on a large scale in the treatment of gastrointestinal disorders and stimulate circulation . Moreover, it is used as antibacterial material and also to address some of the respiratory system, diabetes, food preservation osteoporosis. This study involved the collection of olive leaves from different areas in Baghdad / Iraq. These leaves have been harvested, wash it, then dried and crushed, where the study aimed to identify the active ingredients and chemical elements in the olive leaf as well as its effect on the action of GOT enzyme .The study showed that the aqueous extracts (cold and hot) of the olive leaves powder are acidic in nature pH values are of (5.74 and 5.40) for the aqueous extracts hot and cold respectively. Study revealed the extract contain the a collection of Glycosides, tannins, phenolic compounds, resins, flavonoids, alkaloids, terpenes and compound Alaolurobin. The study also showed ability to activate the enzyme GOT in cold aqueous extract (8.36%). and the percentage (27.35%) of hot aqueous extract. That can be analyzed to the presence of higher concentrations of the active compounds in hot aqueous extract compared with cold aqueous extract especially tannins working to activate enzymes carrier in the cell membrane in the body. The study showed that the analysis of thin layer chromatography, liquid high-performance, ( TLC, HPLC) in extract compounds of phenols olive leaf using a mixture (chloroform, acetic acid) and a 2:5 was more impact in the Gram-positive Staphylococcus aureus, while less impact in a negative Gram Salmonella typhimurium. As proved accurate analysis of the chemical elements in powder of plant leaf olive tree and at different concentrations contain of chemical elements Major estimated by (g /kg) and trace estimated by (mg/kg). Since the existence of these elements led to increasing of enzymatic effectiveness through an increase process of activity the enzyme (GOT), which plays role of important in our bodies being gives indication of the nature of the work and effectiveness of the activity of some members of the body (liver, kidney, pancreas, etc.).
The temperature control process of electric heating furnace (EHF) systems is a quite difficult and changeable task owing to non-linearity, time delay, time-varying parameters, and the harsh environment of the furnace. In this paper, a robust temperature control scheme for an EHF system is developed using an adaptive active disturbance rejection control (AADRC) technique with a continuous sliding-mode based component. First, a comprehensive dynamic model is established by using convection laws, in which the EHF systems can be characterized as an uncertain second order system. Second, an adaptive extended state observer (AESO) is utilized to estimate the states of the EHF system and total disturbances, in which the observer gains are updated

The synthesized compounds were characterized by using some Spectral data (UV, FT-IR, and 1H-NMR).
A novel demountable shear connector for precast steel-concrete composite bridges is presented. The connector uses high-strength steel bolts, which are fastened to the top flange of the steel beam with the aid of a special locking nut configuration that prevents bolts from slipping within their holes. Moreover, the connector promotes accelerated construction and overcomes the typical construction tolerance issues of precast structures. Most importantly, the connector allows bridge disassembly. Therefore, it can address different bridge deterioration scenarios with minimum disturbance to traffic flow including the following: (1) precast deck panels can be rapidly uplifted and replaced; (2) connectors can be rapidly removed and replaced; and (
... Show MoreSoil improvement has developed as a realistic solution for enhancing soil properties so that structures can be constructed to meet project engineering requirements due to the limited availability of construction land in urban centers. The jet grouting method for soil improvement is a novel geotechnical alternative for problematic soils for which conventional foundation designs cannot provide acceptable and lasting solutions. The paper's methodology was based on constructing pile models using a low-pressure injection laboratory setup built and made locally to simulate the operation of field equipment. The setup design was based on previous research that systematically conducted unconfined compression testing (U.C.Ts.). Th
