Uncrosslinked polymers (thermoplastics), on the other hand are freer to wander into the adjacent phase by extending tails and loops across the interface. Another circumstance under which diffusive bonding occurs is “scission”. Chain scission is the cutting up of polymer chains, resulting in a higher concentration of distal tails. The ...

Because the masonry veneer is non-structural, it must be tied back to the building structure to prevent movement under wind and earthquake loads. Brick ties are used for this purpose, and may take the form of corrugated metal straps nailed or screwed to the structural framing, or as wire extensions to horizontal joint reinforcement in a fully masonry veneer or cavity wall.
Other than surgery, endometriosis and pelvic inflammatory disease are typical causes. Surgery inside the uterine cavity (e.g., suction dilation and curettage , myomectomy , endometrial ablation ) may result in Asherman's syndrome (also known as intrauterine adhesions, intra uterine synechiae), a cause of infertility.
Due to the short range of the adhesion forces, the nature of the surface layer of the substrate is crucial. It must be sufficiently firmly connected to the body of the substrate. For example, many adhesives adhere well to a corroded steel surface. However, the corrosion layer – the rust – is not firmly connected to the substrate.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Most commonly, it refers to medication or drug compliance, but it can also apply to other situations such as medical device use, self care, self-directed exercises, or therapy sessions. Both patient and health-care provider affect compliance, and a positive physician-patient relationship is the most important factor in improving compliance. [ 1 ]
