A novel method for the degradation of human blood clot by immobilised bromelain using multi-walled carbon nanotube and polyphenol oxidase
...Show More Authors

Pathological blood clot in blood vessels, which often leads to cardiovascular diseases, are one of the most common causes of death in humans. Therefore, enzymatic therapy to degrade blood clots is vital. To achieve this goal, bromelain was immobilized and used for the biodegradation of blood clots. Bromelain was extracted from the pineapple fruit pulp (Ananas comosus) and purified by ion exchange chromatography after precipitation with ammonium sulphate (0-80 %), resulting in a yield of 70%, purification fold of 1.42, and a specific activity of 1175 U/mg. Bromelain was covalently immobilized on functionalized multi-walled carbon nanotubes (MWCNT), with an enzyme loading of 71.35%. The results of the characterization of free and immobilized bromelain demonstrated that the optimum pH for free and immobilized bromelain activity was 7.0, while the pH range of stability was from 5.0 to 8.5 and 4.0 to 9.0, respectively. The optimum temperature for free and immobilized bromelain activity was 45ºC, whereas the stability was 15 to 50°C and 15 to 55°C, respectively. The immobilized bromelain activity was decreased after the fifth reuse, and the storage period of the free and immobilized bromelain was decreased after 6 and 123 days, respectively. Casein was the best substrate-free bromelain, and fibrin was the best substrate for immobilized bromelain. The results of the purification of polyphenol oxidases (PPO) from potatoes by ion exchange chromatography gave a yield of about 54 %, a purification fold of 1.27, and a specific activity of 2804 U/mg. The current study showed that the immobilized bromelain can significantly biodegrade human blood clots in vitro, while the PPO enzyme has no significant effect on blood clots.

Biotreatment of Actual Potato Chips Processing Wastewater with Electricity Generation in Microbial Fuel Cell
...Show More Authors

This study aimed to investigate the feasibility of treatment actual potato chips processing wastewater in a continuously operated dual chambers microbial fuel cell (MFC) inoculated with anaerobic sludge. The results demonstrated significant removal of COD and suspended solids of more than 99% associated with relatively high generation of current and power densities of 612.5 mW/m3 and 1750 mA/m3, respectively at 100 Ω external resistance.

Evaluation of Drinking Water Quality in Al Wahda Treatment Plant in Baghdad City- Iraq
...Show More Authors

This study aims to evaluate drinking water quality at the Al Wahda plant (WTP) in Baghdad city. A conventional water treatment plant with an average flow rate of 72.82 MLD. Water samples were taken from the influent and effluent of the treatment plant and analyzed for some physicochemical and biological parameters during the period from June to November 2020. The results of the evaluation indicate that treated water has almost the same characteristics as raw water; in other terms, the plant units do not remove pollutants as efficiently as intended. Based on this, the station appears to be nothing more than a series of water passage units. However, apart from Total dissolved solids, the mean values of all parameters in th

"Words of threat in Hebrew language- Pragmatic study": ביטויי האיום בלשון העברית (עיון פרגמטי)
...Show More Authors
The present study approaches an analytical and deliberative analysis of the words of threat in number of Hebrew language examples through exploring all the reasons and conditions of threat act. Moreover, and because of the difficulty to make a distinction between the two verbs, the study discusses the use of the verbs “to warn and to threat” as one of the most common types verbs used in Hebrew language that implies internal threat. Threat is one of most prominent speech acts that language users resort to as a means to achieve intended threat goals. In Hebrew, it is expressed in different ways and depends on different aspects, including (internal and external context, circumstances in which the threat is made, the

Comparison of Ionospheric Total Electron Content Measurements with IRI- 2012 Model Predictions Over Athens
...Show More Authors

Total Electron Content measurements derived from Athens station ionograms (ITEC),
located near Iraq, during the ascending phase of solar cycle 24 (July 2009- April 2010),
according to availability of data, are compared with the latest version of the International
Reference Ionosphere model, IRI-2012 (IRI TEC), using two options (NeQuick, IRI01-
Corr) for topside electron density.
The results obtained from both (ITEC and IRI TEC) techniques were similar, where
correlation coefficients between them are very high. Generally, the IRI predictions
overestimate the ITEC values.

Detection of Chlamydia Pneumoniae in Lung Tissues Derived from Lung Tumor-Bearing Iraqi Patients
...Show More Authors

Chlamydia pneumoniae is an intracellular gram-negative bacteria associated with lower and upper respiratory tract infections. Several studies, mostly achieved by serological assays, proposed a role for this bacteria in lung cancer risk. Therefore, this study aimed to evaluate the prevalence of Chlamydia pneuomoniae in fresh lung tissues of a sample of Iraqi patients with lung tumors, utilizing polymerase chain reaction (PCR) technique. . Chlamydia pneumoniae DNA was detected in 86.67% of samples. Besides, DNA sequencing of 16S rRNA gene revealed that our isolate is closely related to Chlamydia pneumoniae TW183 strain. It is concluded that Chlamydia pneumoniae  is found in fresh l

Historical origins of Hellenistic architecture in ancient North African civilizations: رويدة فيصل موسى النواب
...Show More Authors

Hellenistic architecture represents an important example of the reflection of ancient Greek architecture in the art of oriental architecture in the countries of the ancient world, including those states spread across North Africa that were under the authority of the Ptolemies and who were able to transmit those artistic values and traditions of Greek architecture to those regions. The current research deals with a detailed study of those important transformations of civil and religious architecture, as well as the most important features of that architecture through the constituents of location and geographical location.

Theoretical Analysis of Composite RC Beams with Pultruded GFRP Beams subjected to Impact Loading
...Show More Authors

Glass Fiber Reinforced Polymer (GFRP) beams have gained attention due to their promising mechanical properties and potential for structural applications. Combining GFRP core and encasing materials creates a composite beam with superior mechanical properties. This paper describes the testing encased GFRP beams as composite Reinforced Concrete (RC) beams under low-velocity impact load. Theoretical analysis was used with practical results to simulate the tested beams' behavior and predict the generated energies during the impact loading. The impact response was investigated using repeated drops of 42.5 kg falling mass from various heights. An analysis was performed using accelerometer readings to calculate the generalized inertial load. The in
