De Dion-Bouton engine with monobloc cylinder heads, but cylinders separate from crankcase c. 1905 [1]. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later.
Depending on the laminoplasty technique, the surgeon may repair the vertebral lamina plane with rigid or semi-rigid fixations. Autograft and allograft bone blocks also may be used, but are dependent on the technique. The four most common techniques are Z-shaped, en bloc, open door, and double door laminoplasty. [4]
The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach, the first and second portions of the duodenum, the head of the pancreas, the common bile duct, and the gallbladder. Lymph nodes in the area are often removed during the operation as well (lymphadenectomy ...
Turning 'en bloc, rather than the usual twisting of the neck and trunk and pivoting on the toes, is when PD patients keep their necks and trunks rigid, requiring multiple small steps to accomplish a turn. Camptocormia [1] is a stooped, forward-flexed posture.
The technique spread to straight-six engines and was commonly used by the mid-1920s. Up until the 1930s, most V engines retained a separate block casting for each cylinder bank, with both bolted onto a common crankcase (itself a separate casting). For economy, some engines were designed to use identical castings for each bank, left and right.
The resected size and shape can be controlled, en bloc resection is possible even in a large neoplasm, and neoplasms with submucosal fibrosis are also resectable. So this technique can be applied to the resection of complex neoplasms such as large neoplasms, ulcerative non-lifting neoplasms, and recurrent neoplasms.
The technique was developed for brain tissue, but it is widely applicable for any biological samples. [1] A serial block-face scanning electron microscope consists of an ultramicrotome mounted inside the vacuum chamber of a scanning electron microscope .
En bloc clip and 8mm ammo for the Gewehr 88 Swedish Mauser stripper clip loaded with Swedish 6.5×55mm. The bolt-action Krag–Jørgensen rifle, designed in Norway in 1886, used a unique rotary magazine that was built into the receiver. Like Lee's box magazine, the rotary magazine held the rounds side-by-side, rather than end-to-end.
