1. Chapter 4, §1: 2. Suppose that F is a field and that a and b are in F. Suppose that a · b = 0, and that b = 0. Let c be the inverse of b. Multiplying the equation above by c on the left, we get 0 = 0 · c = (a · b) · c = a · (b · c) = a · 1 = a. Thus a = 0. It follows that F is an integral domain. 8. We compute a b c d 1 0 0 0 = a 0 c 0 , and 1 0 0 0 a b c d = a b 0 0. If we have equality, th...

BACKGROUND Caesarean scar pregnancy (CSP) is a late serious complication of caesarean section. The incidence of CSP has increased worldwide in recent years. Early diagnosis and prompt therapy are crucial to avoid catastrophic complications. There are various strategies for CSP treatment, but there is no consensus on the best management for CSP. Dilation and curettage (D&C) and hysteroscopy are ...

BACKGROUND Pelvic infection, unsafe abortion and previous laparatomy are risk factors for tubal infertility among Nigerian women. Reports on the relationship between these factors and tubal pathology seen on hysterosalpingography (HSG) from our environment have been few. OBJECTIVE To assess the prevalence of tubal occlusions among patients referred for HSG and examine the association between ...
