Class E power amplifier circuit consists mainly of a transistor operates as a switch, load network and series LC filter tuned to fundamental frequency. There is different configurations to realize class E power amplifier circuit according to the load network such as: shunt capacitance configuration, shunt inductance configuration and parallel circuit configuration. In this paper the performance parameters (such as: PAE, overall efficiency, drain efficiency, gain, drain voltage and current waveforms) of class E power amplifier with shunt capacitance configuration at frequencies [0.25, 0.5, 0.75 and 1 GHz] are observed

This paper presents a synthesizing design of a linear antenna array by adapting the Schelkunoff method. The idea behind this type of design is to produce nulls in radiation pattern of a structure without any notable effects on the main lobe. This design has been undertaken around 9 GHz, where both theoretical and simulation results are achieved and will be the target of this work. X-band searching radar system is considered where sing

Produced water from carbonate reservoir can be reinjected into the formation to stimulate hydrocarbon production in aging wells. This is known as water injection or water flooding. This is the most economically friendly method of produced water disposal. In this paper, a laboratory approach to compare and evaluate the efficiency of formation and sea water injection for enhancing oil recovery at room condition in carbonate reservoirs. The main objective of this paper to achieve the maximum oil recovery for the limestone rock by using formation and sea water. This study was conducted using several samples of limestone rock saturated with oil by placing them in the reservoir conditions by placing them in a vacuum oven to ensure complete saturation of the samples with oil and then extracting the oil from them using liquid permeability where the samples are injected by formation and sea water. The oil recovery by formation water injection is range from 26.4 % to 47 %. The oil recovery by sea water injection is range from 0.00 % to 10 %. The oil recovery factor for formation water injection is higher than the oil recovery factor for sea water injection.

The implementation of Building Information Modeling (BIM) in the Libyan construction industry is still in its early stages. However, there is a growing interest in BIM among industry professionals due to its potential to improve project efficiency, reduce errors, and enhance collaboration between project stakeholders. There is potential for significant growth in the future as industry professionals become more familiar with BIM and its benefits and as the government and industry associations take steps to promote its adoption. This study investigates the potential of Building Information Modeling (BIM) implementation and the barriers to non-implement BIM in the Libyan construction sector. 500 questionnaires were sent out via online survey, and 101 completed questionnaires were returned and analyzed using the mean index and ranking method as part of the investigation. The study's findings indicated that BIM currently can be used in the design and operation stages, and it is strongly advised that might be implemented for all phases of Libyan building over the project lifecycle.

We aim to offer this abstract in order to understand the system capable of tracking

meat products using a digital ledger technology known as (Blockchain technology), we will

highlight their mechanism of work and the benefits and pitfalls to avoid. The traceability system for food was published in July 2007 by the International Standards Organization and prepared by the Technical Committee: ISO/TC 34/SC 17.

Tractability increases the correct information that must be recorded in all supply chains. It ensures that every element in the supply chain is controlled, which is used as an evaluation tool to combat meat fraud and enhance meat safety. It is utilized to satisfy consumers by defending the authenticity of meat products, supporting operating and production systems, and strengthening meat markets. Blockchain technology is a modern technology whose mechanism relies on an advanced database that allows information to be shared transparently within a food network, specific to the type of product or commercial activity. The technology in the meat industry stores data in blocks that are connected to each other in a seamless manner and displays it when needed by manufacturers, customers, suppliers, and wholesalers. Blockchain technology contributes to bringing about revolutionary changes and a qualitative shift in the development of various sectors because it offers a new concept for creating, organizing, proving, and transferring data. The blockchain constitutes a decentralized digital record called a “digital ledger,” which is available, distributed, and authenticated among all participants in the blockchain network.

Blockchain technology in the meat industry would be defined as the main and central record for

monitoring and tracing all activities using IoT, in which all industrial practices are recorded, from

the processing of raw materials and additives through supply chains. Blockchain should be used

as a tool to prevent meat-borne diseases and reduce fraud in the meat industry. Traditional food

supply methods are ineffective or not properly documented, which can result in fraud and errors in food processing, making them difficult to trace. Therefore, we advise meat suppliers to utilize both the tractability system and blockchain technology because both are tools to digitize meat

products. In summary, applying the tracking system and digital ledger technology in the manufacture of meat products increases the organization of the flow of control and monitoring processes, which leads to improved transparency and real-time coordination between manufacturers, trading partners, and even consumers.

ABSTRACT Coronary artery disease (CAD) is quite common among diabetics in all age groups and its risk is independently affiliated with Lipoprotein-associated phospholipase A2 (LP-PLA2). There is strong evidence that the elevated plasma level of Lp-PLA2 indicates vascular inflammation associated with plaque formation within the arteries. Therefore, the relationship between the plasma Lp-PLA2 level and coronary

artery disease risk factors between non-diabetic and diabetic patients will be studied. Materials and Methods: A total of 181 individuals were recruited from the National Heart Centre Tajoura and divided into 4 groups (40 healthy controls (HC), 43 non-diabetics (NDM) who had CAD, 54 DM2 without CAD, and 44 DM2 who had CAD). The relationship between Lp-PLA2 and the potential biochemical risk markers for CAD will be studied between the groups. Results: All the groups that participated in this study have similar body mass index. There is statistical significance in the level of plasma level Lp-PLA2 between DM2 with CAD, DM2 without CAD and HC with ( ***P<0.0001, **P<0.006), respectively; and likewise between NDM with CAD and HC with *P<0.05. Although there is a significant difference between the plasma levels of Lp-PLA2 between the groups below the age of 60 years, there is no statistical significance between the groups above the age of 60 years. Correspondingly, there is a statistical difference in the plasma level of Lp-PLA2 between healthy controls and both DM2 without CAD and DM2 with CAD with (**P<0.006, and ***P<0.0001), respectively. Once more, there is statistical significance in the plasma level of Lp-PLA2 between NDM with CAD and healthy controls with *P<0.05. Furthermore, there is a statistical difference in the serum level of CRP between DM2 with CAD and HC. In addition, there is a positive relationship exists between the duration of diabetes mellitus without CAD and the level of glycated haemoglobin (HbA1c) with **P <0.003 in both genders. Conclusion: In this study, the high level of Lp-PLA2 and CRP strongly indicate the presence of vascular inflammation associated with the formation of arterial atherosclerosis with thrombus formation. These findings are also correlated with diabetic duration and they could be used in the diagnosis and prognosis of coronary artery disease.
