Comparative Analysis of Natural and Synthetic Fibre-Reinforced Composites: Mechanical Properties, Processing, and Sustainability Considerations
Abstract: The development of fibre-reinforced composites has significantly advanced engineering applications due to their excellent strength-to-weight ratio, corrosion resistance, and versatility. Synthetic fibres such as glass and carbon provide superior mechanical performance, but their production is energy-intensive and environmentally harmful. Natural fibres, including jute, flax, banana, and hemp, offer biodegradability, lower cost, and sustainability benefits, though they often fall short in strength and durability. Hybrid composites frequently demonstrate improved performance by …

Effectiveness of Twill Technique Vs Endotracheal Tube Holder on ETT Securement: A Comparative Study
Abstract: Endotracheal intubation is an urgent procedure which is performed on patients who are unconscious and can’t breathe by their own. Endotracheal Intubation keeps an airway open and helps to prevent chocking. When the patient is intubated, maintaining the endotracheal tube placement is essential. In case Endotracheal Tube is not secured, even basic nursing management can cause tubing slippage which is a major factor in causing airway trauma or injuries Aim: …

Bearing Capacity of Double Box Shaped Skirted Footings on Sand
Abstract: The double-box-shaped footing with and without skirt and sand-resting pressure settlement behavior was discussed in this paper. Different parameters are normalised skirt depth (0.25 to 1.5), relative sand density (30 to 60 percent) and sand footing interface state (partially rough and rough). Results of this study showed that a general and local shear failure was observed at a relative density of 50 percent and 60 percent, and 30 percent and …

Health Hazards of Nanoparticles and Environmental Pollutants
Abstract: The exponential growth in the use of nanoparticles and the prevalence of environmental pollutants have raised significant concerns regarding their health hazards. Nanoparticles, owing to their unique physicochemical properties—such as small size, high surface areatovolume ratio, and chemical reactivity—can penetrate biological barriers, including the bloodbrain barrier, and interact at the cellular and molecular levels. This can lead to oxidative stress, inflammation, and cellular dysfunction, ultimately resulting in potential toxicity. Similarly, …

Assessment of Matrix Cracking and Fiber Breakage in Hybrid Composite Materials.
Abstract: Hybrid composite materials, combining two or more distinct fiber or matrix constituents, have emerged as advanced structural solutions for aerospace, automotive, marine, and civil engineering applications. However, their complex microstructure makes them susceptible to multiple interacting damage mechanisms, particularly matrix cracking and fiber breakage. This study provides a comprehensive assessment of these damage modes, emphasizing their initiation, evolution, and combined effects on the mechanical integrity of hybrid composites. Matrix cracking …

Development of A Systematic Strategy for Maintenance of Rural Road Network
Abstract: The lack of year round access to many rural communities is a serious constraint to social and economic development of rural road. Poor access limits the effectiveness of agricultural, commercial, educational and health initiatives though unreliable travel and high unit transport costs for crops, goods, services and people.. However, experiences have shown that these roads, although relatively cheap to construct, are often an unsustainable maintenance burden for many rural communities …

Effect of Nanoclay Loading on Physical and Mechanical Properties of Epoxy Composites
Abstract: The effects of multilayer silicate loading on hardness, tensile, and impact properties were examined by developing epoxy–nanoclay composites with 0–5 wt% nanoclay. A desirable compromise between reduced void content and higher Shore D hardness was reached with an ideal nanoclay loading of 3 wt%, which reflected improved load transfer and increased matrix stiffness as a result of limited polymer chain mobility. Tensile strength and modulus rose up to 3 wt% …
