Bangladesh produces massive amounts of plastic products to meet the huge population demand. Jashore (Bangladesh) is well-known for discarding huge numbers of plastic caps (PCs). PCs are made up of hard polymer of polypropylene (PP) and high-density polyethylene (HDPE). Jashore was chosen as the study area because huge quantities of PCs are produced here and plastic rope (PR) is prepared using PCs. About 70 % of PCs came from drinking items, 20 % from toiletries items, 7 % from kitchen items, and rest 3 % from unidentified sectors. About 44.0 % of caps were blue, 35.0 % were red, 11.0 % were green, 5.0 % were yellow, 3.0 % were white, and 2.0 % were ash color. About 52 % of caps were prone to damage, 26.0 % were discolored, 15.0 % were slightly damaged, and about 7.0 % were intake. Additionally, different types of ropes (ash color; red color; yellow color, white color, blue color, rasmi, nylon, cotton, jute, and polyester rope) were collected and some mechanical characterization were performed to determine their sustainability. The internal structure of the ash, red, and yellow color PC rope, silk, jute, and cotton rope did not have any structural deformation, but the blue color rope, nylon, and polyester showed a wide range of structural deformation. Tensile strength (TS) was determined using a Universal Testing Machine (UTM), the internal structure was determined using Scanning Electron Microscopy (SEM), and chemical characterization was determined using Fourier Transform Infrared Spectroscopy (FTIR). The characteristics of PR were compared with the characteristics of other ropes. The highest strength was in silky (5315 Mpa) and nylon (2461.5) ropes. FTIR results showed that the chemical structure of C[bond, double bond]O stretching was in 1800 cm, and O[bond, double bond]C[bond, double bond]O stretching was in 2349 cm spectrum in PC samples. It can be said that the strength could be dependent on the chemical composition of the ropes.

This paper presents a preliminary assessment of waste accumulation along riverbanks in Italy, aiming to provide baseline data for future monitoring and management efforts. The study surveyed 18 stations along 16 rivers across different regions of Italy, from north to south, to quantify and characterise the types and abundance of litter present along their banks. Field surveys were conducted by Legambiente citizen scientists applying a standardised protocol to record and categorise litter items systematically.

This study examined the acute effects of dynamic stretching at different velocities on the neuromuscular system. Fourteen participants underwent four experimental sessions in random order: (1) control (lying at rest with the ankle in a neutral position); (2) slow velocity dynamic stretching (50 beats/min; SLOW); (3) moderate velocity dynamic stretching (70 beats/min; MOD); and (4) fast velocity dynamic stretching (90 beats/min; FAST). The stretching protocols consisted of four sets of 10 repetitions and targeted the plantar flexor muscles of the right ankle.

Article Synopsis
- The study investigates which antibacterial solutions are most effective in eradicating biofilms formed by staphylococcal bacteria on titanium surfaces during DAIR surgery.
- Five antibacterial agents are tested: povidone-iodine, rifampicin, silver nitrate, copper sulphate, and chlorhexidine, focusing on their minimum biofilm eradication concentrations (MBEC) against both MSSA and MRSA strains.
- Results indicate that povidone-iodine and silver nitrate are significantly more effective, achieving at least 99.9% reduction in biofilm, compared to others like rifampicin and copper sulphate, which showed limited effectiveness.
Evaluation of interferents in sampling materials for analysis of post-explosion residues (explosive emulsion/ANFO) using gas chromatography-mass spectrometry (GC/MS).

Article Synopsis
- * It focuses on organic contaminants introduced by common materials used in evidence collection and sample processing, such as plastic films and disposable gloves, which can affect results from gas chromatography/mass spectrometry (GC/MS).
- * Findings indicate that certain materials, especially syringe plungers and gloves, can interfere with detecting explosive residues, stressing the need to evaluate materials for contamination risks before sample analysis.
