a streak structure similar to that observed. The simulated structure is composed of several narrow streaks of downward flows and stretches from high-latitudes to low-latitudes of ±30 deg. in both hemispheres. In the lower hemisphere in Fig. 2b, the latitudinal locations of the streaks agree well with those in the southern part of the IR2 image; whereas, in the upper hemisphere, the simulated streaks are located slightly poleward compared with those in the northern part of Fig. 2a. There is a notable qualitative morphological similarity between the simulated and the observed streak structure, although there are quantitative differences between them. As shown later in Fig. 2e, the downward flows composing the narrow streaks at the altitudes of about 60 km penetrate down to the altitudes of about 50We talk about sex and sexuality

Topic 23: Circumcision

Male circumcision (from Latin circumcidere, meaning “to cut around”) is the surgical removal of the foreskin (prepuce) from the penis. It is estimated that one-third of males worldwide are circumcised. It is most prevalent in the Muslim world (where it is near-universal), parts of Southeast Asia, Africa, the United States and Oceania; it is relatively rare in Europe, Latin America, parts of Southern Africa, and most of Asia. The origin of circumcision is not known with certainty; the oldest documentary evidence for it comes from ancient Egypt. Various theories have been proposed as to how it began, including as a religious sacrifice and as a rite of passage marking a boy’s entrance into adulthood. It is considered religious law in Judaism
