Abstract

Background: This study aimed to assess the effect of cisplatin-induced toxicities on biochemical and pathological parameters such as body, liver, and kidney weights, blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), and blood cells (RBCs and WBCs) in white Swiss albino mice. Methods: Cisplatin’s potential toxic effects on body, liver, and kidney weights were evaluated using standard laboratory methods. Blood biochemical levels such as BUN, creatinine, and ALT levels were determined by an auto-hemolyzer using commercial diagnostic kits. Blood cells (RBCs and WBCs) were counted under a microscope by a hemocytometer. Results: Cisplatin’s potential toxic effects on body, liver, and kidney weights were evaluated using standard laboratory methods. Blood biochemical levels such as BUN, creatinine, and ALT levels were determined by an auto-hemolyzer using commercial diagnostic kits. Blood cells (RBCs and WBCs) were counted under a microscope by a hemocytometer. Conclusions: This study suggested to increase caution when using cisplatin, particularly at high doses. Further investigation shall be performed to minimize its toxic effect and optimize its use.

Abstract

The pre garments waste consisting of offcuts, trimmings, rejected materials are generated from the garments industry is growing concern nowadays. The recent trend of sustainability practice finds a way to convert this garment waste into composite materials by giving second life. The composites material from garment waste has proven that it is while effective alternative of conventional wood-based materials through the series of mechanical property analysis. The reinforcing garments waste with the help of virgin polypropylene matrix symbolizes the composite material. The amount of fiber reinforcement material and matrix used affects the mechanical and physical characteristics of the composite samples made from textile waste, including tensile strength, elongation, density, and water absorption. The waste-based composite panel board displayed a maximum strength of 31.6 N/mm2, with 40% of its volume taken up by fiber reinforcement components and 60% volume by the matrix. The present study demonstrate that the mechanical and physical characteristics of waste-based composite panel boards are comparable to those of current oriented strand boards and commercial plywood. This waste base composite board can be used for false ceilings, hardboard, wall covering, and fashion purposes also. The results of this study can significantly reduce environmental pollution and offer a practical method for recycling garments waste.

Abstract

The bangla alphabet includes vowels, consonants, and compound symbols. The compound nature of bangla is a product of combining two or more root bangla characters into one graph. They are difficult to differentiate because they have a sophisticated geometric shape and an immense variety of scripts used by different places and individuals. This is one of the greatest challenges in creating effective optical character recognition (OCR) systems for bangla. In this paper, a deep convolutional neural network (DCNN)-based system is presented to identify bangla compound characters with high precision. The model was trained using the AIBangla dataset. It has about 171 classes of bangla compound characters. A DCNN system, BonoNet, was designed to classify compound characters. BonoNet outperformed all other state-of-the-art architecture on the test set and improved over current state-of-the-art architecture methods. BonoNet will greatly improve the automation and analysis of the bangla language by accurately identifying these compound complex characters.

Abstract

Metamaterials possess the capability to enhance fifth-generation (5G) communication technology. This article proposes an innovative construction of a miniature metamaterial absorber (MMA) with a dramatically improved effective medium ratio (EMR) characterized by utilizing a multi-square split-ring resonator (MSSRR) MMA unit cell specifically designed for operation in the 5G sub-7 GHz and Sub-8 GHz frequency bands. The unit cell of the MMA is designed using a commercially available FR-4 material with εr=4.3, which is cost-effective. The proposed MMA achieves a remarkably high EMR of 9.83, indicating superior compactness and design efficiency. The MMA of interest operates with absorbance peaks of 70.632%, 96.936%, and 79.930% within the frequencies of 3.554 GHz, 4.940 GHz, and 8.335 GHz, respectively. Along with the absorption analysis, our examination also includes E-field, H-field, surface current, and power flow. The expected MMA has proven potential for application in some frequency bands related to 5G, released absorption signal, and specific absorption rate (SAR) assistance.
