This paper presents issues related to the determination of the selected mechanical properties of adhesive joints made of polymeric pipes and the evaluation of the leak-tightness of the adhesive joints. The article attempts to demonstrate that the type of adhesive may affect the quality of adhesive joints in terms of both tightness and strength of joints. Five types of the polymer pipes differing in a polypropylene and a polyvinyl chloride, diameter and a wall thickness were used in the experiments. Two types of the adhesives were used to make the adhesive joints: Loctite 3430 A&B Hysol, a two-component epoxy adhesive, and Loctite 406, a one-component cyanoacrylate adhesive. Based on the leak-tightness tests results, it was possible to determine the quality of their adhesive joints without damaging the samples, while their tensile strength was determined through the strength tests. The tests performed allowed for the conclusion that the use of the polyvinyl chloride pipes and Loctite 406 one-component adhesive is recommended for this type of adhesive joints.

Pain is an unpleasant sensory and emotional experience that can affect the quality of life and leads to decreased productivity in patients. Low back pain (LBP) is one of the significant causes of disability worldwide with lifelong incidence. The purpose of this literature review describes the potential of anthocyanin-based Poly (Methyl Methacrylate) (PMMA) nanoparticles as the management of inflammatory pain in the Hernia Nucleus Pulposus (HNP ). The method used is a literature study by entering the keyword. Of the 77 journals reviewed, 47 journals were found by the topic and used as a reference for this work. The anthocyanin-based PMMA nanoparticles act as anti-nociceptors by inhibiting microglia that produce inflammatory mediators in HNP. Poly (Methyl Methacrylate) nanoparticles have specific targets in microglia. Anthocyanins have the effect of inhibiting inflammatory pain through many destinations. Anthocyanin inhibits the synthesis of nitric oxide (NO ) and prostaglandin E2 (PGE 2) and inhibits the activation of p38 MAPK and NF-kB pathways that express TNF-α and IL-1β genes as anti-nociceptive. The anthocyanin-based PMMA nanoparticles have potential as a novel therapy for inflammatory pain in HNP. There has been no research between these modalities. Therefore, further research is needed to find out the exact potential of anthocyanin-based PMMA nanoparticles.
