Sexually transmitted disease (STD) is a general term that refers to as many as twenty different illnesses. These are transmitted by sex - usually through the exchange of bodily fluids such as semen, vaginal fluid, and blood. STD's such as herpes, can be acquired by kissing or close contact with infected areas - not just intercourse. If left untreated, STD's can cause permanent damage that leaves you blind, brain-damaged, or sterile. The most common STD's are chlamydia, herpes, gonorrhea, genital warts, syphilis, hepatitis B, crabs, and trichomoniasis. STD's can be prevented, most can be cured. They infect men, women, and children. Mothers can also transmit STD's to their babies. Anyone at any age can be a victim. It is not true that having had an STD once and having been cured, you will not get it again. Anyone who has sex can get a sexually transmitted disease and millions do. More than 4 million people get chlamydia each year. Genital herpes affects an estimated thirty million Americans, with as many as 500,000 new cases reported each year. There are over one million cases of gonorrhea each year. And syphilis, once thought to be on the decline, made a rising comeback in the 1990s. Research Sexually Transmitted Diseases
Syphilis is a venereal disease (VD, STD) due to the micro-organism Treponema Pallidum. It is usually transmitted by sexual contact with an infected person, but may also be transmitted by contact with an infected person through cuts or scratches in the skin, making medical staff particularly at risk of contracting the disease. The initial stage of syphilis is a 'chancre' which resembles a large infected wart. It appears on the lips or in the genital area, but frequently this stage of the disease is overlooked and heals spontaneously.
Primary syphilis, as this stage is called, may then pass unnoticed. The secondary stage lasts for several weeks and is characterised by rashes and ulcerative lesions in the mouth. This stage also may be overlooked and if treatment is not instituted the patient will develop tertiary syphilis of which there are various manifestations. One is the development of a syphilitic tumour or gumma which breaks down and produces an ulcer - gummatous ulcer. Tertiary syphilis also affects the nervous system, producing tabes dorsalis (locomotor ataxia). In this condition the victim develops degenerative changes in the joints (Charcot's joints) and perforating ulcers in the feet. The child of an infected mother may be born with congenital syphilis which shows itself during the first two or three years of life in special changes which affect the child's bones, liver and eyes.

The Bofors 40 Mk3 gun is a 40 mm Naval multipurpose gun with the capability to engage all types of targets. This extremely accurate gun is capable of firing any 40 mm L/70 ammunition, but the highest performance is achieved when using Bofors 40 mm 3P ammunition. The ready-to-use magazine holds a total of 101 rounds, enough for between ten and twenty engagements without reloading. The two magazine compartments can be loaded with different types of ammunition. The operator can, within a split second, switch from one compartment to the other. The Gun Main Computer (GMC) has a built-in event/activity recorder which continuously monitors all the gun-sensors, power supplies and other vital gun functions. The gun is designed for total remote control from the ship Fire Control System. Internal communication within the gun, as well as communication with other units outside the gun, is conducted via a data bus MIL-STD-1553 B. The gun features a sophisticated local control back-up mode using a low-light TV sight. Research Bofors 40 MK3
