A Comparative Review of Conventional Mechanical and Solar‐Driven Cooling Technologies: Performance and Environmental Perspectives
...Show More Authors
ABSTRACT<p>Conventional cooling systems are major energy consumers in hot climates, directly contributing to increased carbon emissions and placing a significant strain on Iraq's national electricity grid. This study aims to explore and evaluate clean and sustainable alternatives to conventional systems. The methodology is based on a comparative analysis of various cooling technologies, including mechanical, absorption, adsorption, drying, and hybrid systems, using key performance indicators such as the coefficient of performance (COP), energy consumption, carbon emissions, and system cooling capacity. The results show that innovative solar cooling technologies offer superior operational efficiency and significantly lower carbon emissions compared to mechanical systems. Single‐effect absorption systems are the optimal choice for the local climate, as they can operate efficiently at operating temperatures (80°C–85°C) achievable with evacuated solar collectors. Furthermore, integrating thermal storage (PCM) technologies reduces system performance fluctuations, reaching approximately 33.5% [1], thus ensuring cooling stability. Based on an in‐depth analysis of the latest available literature, it is possible to save up to approximately 45% [2, 3] of the energy consumed by harnessing the abundant solar radiation in Iraq for most days of the year, depending on the type and efficiency of the system used.</p>

Effect of Mixed Corrosion Inhibitors in Cooling Water System
...Show More Authors

The effect of mixed corrosion inhibitors in cooling system was evaluated by using carbon steel specimens and weight loss analysis. The carbon steel specimens immersed in mixture of sodium phosphate (Na2 HPO4) used as corrosion inhibitor and sodium glocunate (C6 H11 NaO7) as a scale dispersant at different concentrations (20,40, 60, 80 ppm) and at different temperature (25,50,75 and 100)ºC for (1-5) days. The corrosion inhibitors efficiency was calculated by using uninhibited and inhibited water to give 98.1%. The result of these investigations indicate that the corrosion rate decreases with the increase the corrosion inhibitors concentration at 80 ppm and at 100ºC for 5 days, (i.e,

Role of Artificial Intelligence in Enhancing Efficiency and Sustainability in Middle Eastern Oil and Gas: A Review
...Show More Authors

This review examines how artificial intelligence (AI) including machine learning (ML), deep learning (DL), and the Internet of Things (IoT) is transforming operations across exploration, production, and refining in the Middle Eastern oil and gas sector. Using a systematic literature review approach, the study analyzes AI adoption in upstream, midstream, and downstream activities, with a focus on predictive maintenance, emission monitoring, and digital transformation. It identifies both opportunities and challenges in applying AI to achieve environmental and economic goals. Although adoption levels vary across the region, countries such as Saudi Arabia, the UAE, and Qatar are leading initiatives that align with global sustainability targets.

Identifying Factors Affecting the Morphological Changes of River Estuaries and Techniques for Analysis and Control: A Review
...Show More Authors

Erosion and deposition are natural phenomena in many estuaries that can cause morphological changes, leading to navigation and offshore structure problems. Many previous studies have focused on investigating the morphological changes of estuaries depending on different parameters and their combined effects with erosion and deposition processes, such as maximum flow amplitude, waves, currents, tidal flow, storms, rising sea elevation, maximum turbidity, salinity, and bed roughness height as input parameters. These studies are based on field measurements and numerical simulations by using topographic surveys, soil samples, satellite images, geological data, and bathymetric maps with the aid of ArcGIS. Some of these studies examine the

Microleakage Evaluation of a Silorane-Based and Methacrylate-Based Packable and Nanofill Posterior Composites (in vitro comparative study)
...Show More Authors

This study compared in vitro the microleakage of a new low shrink silorane-based posterior composite (Filtek™ P90) and two methacrylate-based composites: a packable posterior composite (Filtek™ P60) and a nanofill composite (Filtek™ Supreme XT) through dye penetration test. Thirty sound human upper premolars were used in this study. Standardized class V cavities were prepared at the buccal surface of each tooth. The teeth were then divided into three groups of ten teeth each: (Group 1: restored with Filtek™ P90, Group 2: restored with Filtek™ P60, and Group 3: restored with Filtek™ Supreme XT). Each composite system was used according to the manufacturer's instructions with their corresponding adhesive systems. The teeth were th

A Review of TCP Congestion Control Using Artificial Intelligence in 4G and 5G Networks
...Show More Authors

In recent years, the field of research around the congestion problem of 4G and 5G networks has grown, especially those based on artificial intelligence (AI). Although 4G with LTE is seen as a mature technology, there is a continuous improvement in the infrastructure that led to the emergence of 5G networks. As a result of the large services provided in industries, Internet of Things (IoT) applications and smart cities, which have a large amount of exchanged data, a large number of connected devices per area, and high data rates, have brought their own problems and challenges, especially the problem of congestion. In this context, artificial intelligence (AI) models can be considered as one of the main techniques that can be used to solve ne

Agenesis of flexor pollicis longus without thenar hypoplasia: a case report and literature review
...Show More Authors
Abstract<p>We present a case of congenital of flexor pollicis longus agenesis without thenar hypoplasia in a 12-year-old girl with no history of trauma. Two-staged corrective surgery was planned. In the first stage, the flexor pulley was reconstructed using silicone followed by the second stage 3 months later when flexor pollicis longus reconstruction was performed using tendon transfer of the flexor digitorum superficialis. The patient completed post-operative physiotherapy and the result of the surgical treatment in both functional and cosmetic aspects was, in the authors’ opinion, excellent.</p>

Power requirements for corn silage harvesters and application of precision agricultural techniques: a review
...Show More Authors

The energy requirements of corn silage harvesters and the application of precision agricultural techniques are essential for efficient and productive agricultural practices. The article aims to review previous studies on the energy requirements needed for different corn silage harvesting machines, and on the other hand, to present methods for measuring corn silage productivity directly in the field and monitoring it based on microcontrollers and artificial intelligence techniques. The process of making corn silage is done by cutting green fodder plants into small pieces, so special harvesters are used for this, called corn silage harvesters. The purpose of harvesting corn silage is to efficiently collect and store as many digestible nutrien
