Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
A balloon atrial septostomy is performed with a balloon catheter, which is inserted into a patent foramen ovale (PFO), or atrial septal defect (ASD) and inflated to enlarge the opening in the atrial septum; this creates a shunt which allows a larger amount of oxygenated ("red") blood to enter the systemic circulation.
Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
Polydioctylfluorene (PFO) can be found in liquid-crystalline, glassy, amorphous, semi-crystalline or β-chain formation. This variety is on account of the intermolecular forces that PFO can participate in. The secondary forces present in PFO are typically van der Waals, which are relatively weak. These weak forces makes it a solid that can also ...
Atrioventricular septal defect (AVSD) or atrioventricular canal defect (AVCD), also known as "common atrioventricular canal" or "endocardial cushion defect" (ECD), is characterized by a deficiency of the atrioventricular septum of the heart that creates connections between all four of its chambers. It is a very specific combination of 3 defects:
A ventricular septal defect (VSD), a hole in the interventricular septum is one of the four congenital defects of the condition of tetralogy of Fallot. A VSD can cause a left-to-right shunt of blood flow in the heart and is one of the most common of the congenital heart defects.
MSC Industrial Direct Co., Inc (MSC), through its subsidiaries, primarily MSC Industrial Supply Co., is one of the largest industrial equipment distributors in the United States, [1] distributing more than 1.5 million metalworking and other industrial products.
This makes it relatively straightforward to repair complex military hardware, at the expense of having a ready supply of spare parts. The cost of having serviceable parts available in inventory can be tremendous, as items that are prone to failure may be demanded frequently from inventory, requiring significant inventory levels to avoid depletion.
