Three of the most common problems in the male reproductive system are prostate cancer, benign prostatic hypertrophy (BPH), which is a gradual enlargement of the prostate gland, and prostatitis, which is an inflammation of the gland, according to Philip M. Hanno, M.D.1
As men age, the prostate gland increases in size, which is known as benign prostatic hyperplasia/hypertrophy. If the enlargement encroaches on the urinary tube (the urethra), which carries urine from the bladder to the penile opening, obstruction occurs. Symptoms include restricted urinary flow, difficulty in starting the flow, frequent urination during day and night, and the feeling of an urgent need to urinate.
“Until recently,” Hanno said, “over 350,000 men in the United States were undergoing transurethral prostatectomy (TURP) each year to relieve these symptoms. In this procedure, perhaps the most common surgery in urology, the obstructing tissue is removed under anesthesia with an electrified blade placed in the urethra.”

A Board Game (for Two Teams of Two Players Each)
The goal of this game is for you and your partner to capture or block the pieces of the other team. First, you and your partner place your pieces on three diagonal rows of dark squares in one corner. Then, you move diagonally forward along the dark squares to the opposite corner.
Ordinary chess or checker board
24 check pieces: 6 dark plus, 6 light plus, 6 dark circles, 6 light circles.
1. Choose a set of check pieces for each player. The two people with the same color pieces make a team. Sit with players around the game board, with partners next to each other at their corner. Set up the board as shown on the next page.
2. The team with the dark pieces begins. Player 1 moves one space diagonally—forward—along the dark squares towards the opposite corner of the board. A player can capture a check piece by jumping over it and landing on the square beyond it. The captured piece is kept by the jumping player. When a player reaches one of the two squares in the opponent team’s corner, the piece becomes a
Under this definition, the network is made up of intelligent end-point systems that are self-deterministic, allowing each end-point system to communicate with any host it chooses. Rather than being a network where communications are controlled by a central authority (as found in many private networks), the Internet is specifically meant to be a collection of autonomous hosts that can communicate with each other freely.
This is an important distinction, and one that is often overlooked. For example, many of the private networks have offered mail-delivery services for their customers, allowing a user on one network to send email to another user on another network, but only by going through a predefined mail gateway service. Conversely, the Internet allows users to exchange mail directly, without going through a central politburo first. In this regard, the Internet is a collection of self-deterministic, autonomous hosts.
Having hosts communicate with each other directly is not enough to make the
PowerPoint ju dawno zniknby z rynku, gdyby jego moliwoci ograniczay si do umieszczania na slajdach punktorw. Rysunki, fotografie oraz wszelkiego typu grafiki sprawiaj, e pokazy slajdw staj si znacznie ciekawsze i bardziej wyrafinowane. Speniaj one take rol niezwykle przydatnych wskazwek wizualnych, ktre pomagaj osobom ogldajcym prezentacj zrozumie jej kluczowe zagadnienia lub przypomnie sobie o czym, o czym wspominano wczeniej. Oprcz tego grafika pozwala scali pokaz slajdw w logiczn cao (jeli na kadym slajdzie bd uywane podobne elementy graficzne) oraz skojarzy go z pewn mark (jeli jej logo pojawi si na kadym slajdzie).
Dlatego te nie jest niczym dziwnym ani zaskakujcym, e PowerPoint pozwala umieszcza na slajdach przerne elementy graficzne. Moe to by niemal wszystko: zaczynajc od prostych rysunkw, ktre autor sam rysuje bezporednio na slajdzie, przez fotografie i obrazy tworzone w innych programach, a koczc na obiektach clipart doczonych do PowerPointa. Z tego rozdziau dowiesz si, jak umieszcza rysunki i obrazy na slajdach.
