Hartmann
Hartmann is a Germanic and Ashkenazi Jewish surname. It is less frequently used as a male given name. The name originates from the Germanic word, "hart", which translates in English to "hardy", "hard", or "tough" and "Mann", a suffix meaning "man", "person", or "husband". The name Hartman, distinguished by ending with a single "n", is generally the result of the anglicisation of names that occurred with the emigration of persons from German-speaking to anglophone nations in the 18th, 19th and early 20th century. Below is a list of notable individuals and fictional characters with the surname or given name of Hartmann.

Hartmann's Operation
A proctosigmoidectomy, Hartmann's operation or Hartmann's procedure is the surgical resection of the rectosigmoid colon with closure of the anorectal stump and formation of an end colostomy. It was used to treat colon cancer or inflammation (proctosigmoiditis, proctitis, diverticulitis, volvulus, etc.). Currently, its use is limited to emergency surgery when immediate anastomosis is not possible, or more rarely it is used palliatively in patients with colorectal tumours. The Hartmann's procedure with a proximal end colostomy or ileostomy is the most common operation carried out by general surgeons for management of malignant obstruction of the distal colon. During this procedure, the lesion is removed, the distal bowel closed intraperitoneally, and the proximal bowel diverted with a stoma. The indications for this procedure include: :a. Localized or generalized peritonitis caused by perforation of the bowel secondary to the cancer :b. Viable but injured proximal bowel that, in th ...

Hartmann Mask
Hartmann mask is a tool to help focusing telescopes, mainly used by amateur astronomers. It is named after the German astronomer Johannes Franz Hartmann (1865–1936), who developed it around 1900. Theory and practice Every part of a mirror or lens produces the same image as the whole optical element. The light is focused in the focal point. The light rays, however, go through different points of a plane before or behind the focus. This phenomenon can be used when focusing a telescope. The Hartmann mask is a simple opaque mask containing two or three holes. (This device is called a Hartmann mask if it has multiple holes, or a Scheiner disk if it has two holes.) The mask covers the aperture of the telescope. When the apparatus is out of focus, multiple images can be seen if the telescope is pointed towards a bright light source (Moon, bright star). Adjusting the focuser, the images can be made to overlap, forming a single bright, clear picture. The mask may also be used to che ...

Meyer And Hartmann Reaction
Unlike its lighter congeners, the halogen iodine forms a number of stable organic compounds, in which iodine exhibits higher formal oxidation states than -1 or coordination number exceeding 1. These are the hypervalent organoiodines, often called iodanes after the IUPAC rule used to name them. These iodine compounds are hypervalent because the iodine atom formally contains in its valence shell more than the 8 electrons required for the octet rule. Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7. In terms of chemical behavior, λ3 and λ5iodanes are generally oxidizing and/or electrophilic species. They have been widely applied towards those ends in organic synthesis. Nomenclature Several different naming conventions are in use for the hypervalent organoiodines. All begin with nonstandard formal charge assignments. In iodane chemistry, carbon is con ...
