Mansoura Engineering Journal

It had been noticed that 3-phase and 4-phase computed tomography protocols with contrast serve as standard examinations for diagnosing liver tumors. Additionally, many patients require periodic follow-up, which entails significant radiation exposure for them. Advancements in image processing facilitate automated liver lesion segmentation. However, the challenge remains in classifying these small lesions by doctors, especially when the liver has different types of lesions with very little intensity difference. Therefore, deep learning can be utilized for the classification of liver lesions. The present work introduces a CNN-based module for the classification of liver lesions. The module consists of four stages: data …


A Novel Method For The Production Of Pig Iron In “Hadisolb” Company (Industrial-Scale Experiments), El-Sayed A. Rassoul Jan 2024

A Novel Method For The Production Of Pig Iron In “Hadisolb” Company (Industrial-Scale Experiments), El-Sayed A. Rassoul

Mansoura Engineering Journal

The chairman of “Hadisolb” had submitted a memorandum in 1977 in which he claimed that the company will never achieve its designed capacity unless it gets rid of the threatening impurities -high alkalis & MnO- in the blast furnace burden. Meanwhile, the DR steel companies are suffering from the generated accumulated wastes which contain > 67% Fe, zero% alkalis and traces of MnO. The novel idea here is finding the best ratio between El-Gedida ore and the waste material (W.M.). In a previous investigation a series of pilot-scale sintering experiments were performed and it was concluded that the blend containing 70% …

Mansoura Engineering Journal

Buildings are responsible for 39% of global energy-related carbon emissions; 11% come from materials and construction, and 28% come from operational emissions (the energy required to heat, cool, and power). Embodied carbon will contribute an increasing amount to the emissions from new buildings in the future as carbon emissions from building operations continue to decline. This study examined several construction methods and materials to evaluate alternatives for remodeling a residential villa. A villa in the Al-Qassim Region, Buraidah, served as a case study for this research. The methodology employed provided a meticulous appraisal of the building materials and techniques currently …

Influence Of Macro-Synthetic Fibers On The Flexural Behavior Of High Strength Concrete Beams Reinforced With Gfrp Bars, Maryam M. Koura, Ahmed M. Tahwia, Mohamed H. Matthana

Mansoura Engineering Journal

Rusting of steel reinforcement in marine environments causes the overall destruction of reinforced concrete constructions; steel rebars in concrete members have been replaced with fiber-reinforced polymer (FRP) bars in recent years. To enhance the shear behavior of glass (GFRP) bars reinforced concrete (RC), macro-synthetic polyolefin (PO) fiber was added. These materials have a low modulus of elasticity, a high tensile strength, and a linear stress-strain response to full failure. This study investigates the effect of macro synthetic structural fibers on the post-cracking and deformability properties of high strength concrete reinforced with FRP bars without transverse reinforcement. Eight full-scale RC beams …

ASEAN Journal on Science and Technology for Development

The composition of fats and oils significantly impacts the flavour, nutrition, and appearance of food. Excessive consumption of saturated fatty acids, primarily found in animal fats, raises the risk of coronary heart disease. To address this, plant-based fats are used as substitutes, with microalgae offering unique nutritional benefits as a fat source. This study evaluates the performance of structured plant-based fats, incorporating microalgae (Aurantiochytrium sp. SW1), as a fat substitute in chicken patties. Four formulations were tested: 0% (control), 5%, 7%, and 10% structured microalgae-based fat. Colour, texture, water-holding capacity, cooking loss, and microstructure in both raw and cooked samples …

ASEAN Journal on Science and Technology for Development

Sugar content is a superior quality indicator for the post-harvesting and ripening status of climacteric fruits. Total soluble solids (TSS) represented by °Brix index is a measure of the sugar content. The conventional way to measure TSS is by invasive (IN) technique using manual or digital refractometers. While non-invasive (NIN) infrared refractometer devices have been developed in recent years for various agricultural and food science applications, its accuracy to measure fruit TSS directly is not straightforward, as the device is only dedicated to uses for a specific fruit. This study aims to investigate the suitability of the use of a …

ASEAN Journal on Science and Technology for Development

Macrobrachium rosenbergii, or the giant freshwater prawn has high market demand due to its exceptional nutritional value for the human diet. Often, most nutritional studies focus on the edible prawn parts, rather than the prawn discarded components. The nutritional evaluation of different prawn parts can provide insights into the nutrient composition and guiding for the development of value-added products. Three groups of prawn samples were collected from 3 different ponds, representing different prawn sizes. The water quality analysis of each pond was also conducted to determine the extent to which it can affect the nutritional composition. The conventional and biochemical …

ASEAN Journal on Science and Technology for Development

Rice is considered the staple food of Brunei Darussalam, where most rice is imported from different countries. This poses a risk regarding food security wherein an unwanted event of restricted rice importation, Brunei, may experience difficulties. Hybrid rice cultivation is one of Brunei's best food security options. We studied the farmers' attitudes towards mixed rice farming in Brunei. We divided the farmers into two groups for the purpose of our study. Agriculture cooperative members and non-members. For attitude, perceived ease of use positively impacts attitude significantly for member rice farmers, while perceived usefulness positively impacts attitude for non-member rice farmers. …

Exploring The Impact Of Vented Packaging Configurations On Airflow Patterns And Cooling Consistency For Muskmelons In A Cold Storage Environment, Nur Wafidah Roslan, Namasivayam Navaranjan, Zohrah Sulaiman, Naseem Uddin

ASEAN Journal on Science and Technology for Development

The cooling effect of different vented packaging designs was investigated for packed muskmelons fruits in a commercial cold storage condition. Computational fluid dynamics (CFD) simulation and experiments were used. The airflow pattern, heat transfer and temperature profiles were predicted from simulation and analysed. The CFD results reveal an uneven and low efficient airflow distribution inside a commercially used vented packaging (Box A). This resulted slow cooling of the fruits in Box A. Two newly designed packaging (Box B and Box C) showed better airflow distribution around the fruits and cooled them faster than Box A. The design of Box C …

ASEAN Journal on Science and Technology for Development


Tropical marine fish is a main raw material for surimi processing plants, including golden threadfin bream (Nemipterus virgatus Houttuyn, 1782) and swallowtail dwarf monocle bream (Parascolopsis eriomma Jordan & Richardson, 1909). After processing, more than 60% of fish are considered as byproducts (i.e., head, viscera, skin, bones, fins and scale), and tend to discard due to poor-utilization. Hence, this paper aims to evaluate macro- and micro-nutrients derived from golden threadfin bream (GTB) and swallowtail dwarf monocle bream (SDMB). The higher content of protein (25.31 ± 0.81%) was observed in the skin part of GTB, followed by the flesh (21.26 ± …
