The contact angle is the angle, conventionally measured through the liquid, where a liquidâvapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique equilibrium contact angle.
Some sexually transmitted diseases mimic the effects of urinary tract infections. Additionally, certain STDs can cause urinary tract infections if the bacteria spreads to the urethra rather than or in addition to the sex organs. For example, chlamydia can cause urinary tract infections, and its symptoms may be difficult to distinguish from other types of UTIs. Because the risk of UTIs increases in people who are sexually active, patients may not recognize the early signs of an STD or may mistake it for a urinary tract infection.
