It remains important in military engineering, and combat engineers still use dynamite. Alfred Nobel then developed ballistite, by combining nitroglycerin and guncotton. He patented it in 1887. Ballistite was adopted by a number of European governments, as a military propellant. Italy was the first to adopt it. The British government and the Commonwealth governments adopted cordite instead, which had been developed by Sir Frederick Abel and Sir James Dewar of the United Kingdom in 1889. The original Cordite Mk I consisted of 58% nitroglycerin, 37% guncotton, and 5.0% petroleum jelly. Ballistite and cordite were both manufactured in the form of "cords". Smokeless powders were originally developed using nitrocellulose as the sole explosive ingredient. Therefore, they were known as single-base propellants. A range of smokeless powders that contains both nitrocellulose and nitroglycerin, known as double-base propellants, were also developed. Smokeless powders were originally supplied only for military use, but they were also soon developed for civilian use and were quickly adopted for sports. Some are known as sporting powders. Triple-base propellants contain nitrocellulose, nitroglycerin, and nitroguanidine, but are reserved mainly for extremely high-caliber ammunition rounds such as those used in tank cannons and naval artillery. Blasting gelatin, also known as gelignite, was invented by Nobel in 1875, using nitroglycerin, wood pulp, and sodium or potassium nitrate. This was an early, low-cost, flexible explosive. Medical use
Nitroglycerin belongs to a group of drugs called nitrates, which includes many other nitrates like isosorbide dinitrate (Isordil) and isosorbide mononitrate (Imdur, Ismo, Monoket).
Painful bruising syndrome (also known as "autoerythrocyte sensitization", "Gardner–Diamond syndrome", and "psychogenic purpura") is an idiopathic trauma-induced condition seen in young to middle-aged women who sometimes manifest personality disorders. : 829   It is characterized by a distinctive localized purpuric reaction occurring primarily on the legs, face and trunk, with recurring painful ecchymoses variably accompanied by syncope, nausea, vomiting, gastrointestinal and intracranial bleeding.Patients with this condition can experience frequent painful bruising around joints and muscles. Because of the rarity of the disorder, there are few methods of support in place for patients.Many patients are labelled with the stigma of having a psychological condition without this having a specifically proven link. There have been cases of painful bruising syndrome reported where there are no additional psychological disorders. This has been known to be put into remission with chemotherapy. It was characterized in 1955 by Frank Gardner and Louis Diamond.Patient may present with a history of intermittent purpura mostly precipitated by stress. See also
