A rational estimation of volumetric thermal expansion coefficient of AlO-water nanofluid in thermo-fluid application.

A practical approach to augment the heat transmission effectiveness of thermo-fluid systems involves the utilization of nanofluids instead of traditional fluids. The present investigation compares different models for determining nanofluids' volumetric thermal expansion coefficient with the experimental findings. A benchmark problem of free convection is chosen to assess the accuracy of the existing models.

An extensive image dataset for deep learning-based classification of rice kernel varieties in Bangladesh.

This article introduces a comprehensive dataset developed in collaboration with the Bangladesh Institute of Nuclear Agriculture (BINA) and the Bangladesh Rice Research Institute (BRRI), featuring high-resolution images of 38 local rice varieties. Captured using advanced microscopic cameras, the dataset comprises 19,000 original images, enhanced through data augmentation techniques to include an additional 57,000 images, totaling 76,000 images. These techniques, which include transformations such as scaling, rotation, and lighting adjustments, enrich the dataset by simulating various environmental conditions, providing a broader perspective on each variety.

Clinico-epidemiological profiling of dengue patients in a non-endemic region of Bangladesh.

Background: This study aimed to characterise the clinical and epidemiological profiles of dengue patients and their outcomes during an ongoing outbreak in a non-endemic region of Bangladesh.

Methods: This prospective observational study analysed 805 confirmed dengue cases during August-December 2023. Data on demographic, clinical and laboratory profiles, as well as outcomes, were gathered using a structured questionnaire.

Removal of microplastics from aqueous media using activated jute stick charcoal.

Microplastics (MPs), which are repositories of various pollutants, have significant effects on the people and the environment. Therefore, there is an urgent need for efficient and eco-friendly techniques to eliminate microplastics from water-based environments. This study introduces a new method for producing jute stick-activated charcoal (JSAC) by placing jute sticks on high-temperature pyrolysis without oxygen, followed by chemical activation with HCl.
