Adhesive towards the cells properties of three polypropylene net prostheses (PNP), manufactured by "Espera", with the slots size 1 x 1 mm, 2 x 2 mm, 2 x 4 mm and one specimen (the slot diameter 1 mm) on the oxycellulose background, were tested for prognostication of hernioplasty results, using nonresorbable PNP. The adhesion degree and peculiarities of cellular line, obtained from embryonal kidney of pig, put on the tested nets specimen in conditions of cultivation during 5 - 10 days were estimated, using inverted microscope in regime of phasic contrast. The data obtained witness the lowered cellular adhesion towards PNP "Espera" without oxycellular background. The net processing, using components of extracellular matrix, as well as presence of the oxycellulose fragments, facilitate the PNP ingrowth by connective tissue.

There are two major styles of maggot debridement dressings: (1) confinement dressings that form a cage around the wound, and (2) containment dressings that completely surround the maggots within a sealed porous bag. For producers and clinicians wanting to prepare containment dressings using readily available polyester bags, it is currently difficult to seal these bags without expensive high-temperature plastic welders. This study aimed to identify simple and affordable methods for sealing maggots within polyester net bags.

Shipboard domestic sewage, encompassing both black water and gray water, has the potential to transport significant quantities of environmentally harmful microplastics, a concern that has garnered increasing global attention. In this study, Fourier infrared (FTIR) detection was used to detect microplastics in marine domestic wastewater. The primary objective was to evaluate the abundance and characteristics of microplastics present in ship domestic sewage, investigate potential sources and influencing factors, and assess the ecological risks associated with ship sewage through analyses of microplastic abundance and hazard indices.

Estuarine fronts are formed due to sharp density discontinuities resulting from the convergence of different water masses. This study, conducted in May and August of 2022 during the southwest monsoon season, focuses on assessing the role of estuarine fronts at Kuala Terengganu estuary in the accumulation of microplastics in surface seawater. The Terengganu River basin area covers approximately 4600 km and consists of two main tributaries that drain into the Kuala Terengganu estuary.

Pelletizing mixed plastic wastes (MPW) has gained interest as an upcycling technology and an alternative to conventional recycling. To investigate its potential, we conducted a cost analysis and life-cycle assessment (LCA) for a conceptual pelletization facility designed to produce 1 kg of pellets per batch of MPW (comprising polyethylene-PE and polypropylene-PP). This work has the following merits: (i) evaluating environmental impact (EI), cost analysis, and mechanical strength based on actual experimental data and its comparison with local and international manufacturers; (ii) enabling the evaluation of LCA impacts of MPW pellets; and (iii) emphasizing the significance of waste management in reducing EIs.
