Masu apkalpošanas sistēmu tīkli
2021
Šajā darbā tiek sniegts ieskats masu apkalpošanas sistēmu tīklu dažādos veidos, tiek dotas formulas tīklu darbības rādītāju noteikšanai un aprakstīti reizinājumu formas tīkli. Sīkāk tiek apskatīti trīs masu apkalpošanas sistēmas tīklu veidi - Džeksona tīkli, Gordona-Ņūela tīkli un BCMP tīkli. Katram veidam ir arī dots piemērs ar aprēķiniem. Ir arī piedāvāti uzdevumi patstāvīgai risināšanai.
Evaluation of efficacy and biocompatibility of a novel semisynthetic collagen matrix as a dural onlay graft in a large animal model
2011
Background Semisynthetic collagen matrices are promising duraplasty grafts with low risk of cerebrospinal fluid (CSF) fistulas, good tissue integration and minor foreign body reaction. The present study investigates the efficacy and biocompatibility of a novel semisynthetic bilayered collagen matrix (BCM, B. Braun Aesculap) as dural onlay graft for duraplasty. Methods Thirty-four pigs underwent osteoclastic trepanation, excision of the dura, and placement of a cortical defect, followed by duraplasty using BCM, Suturable DuraGen™ (Integra Neuroscience), or periosteum. CSF tightness and intraoperative handling of the grafts were evaluated. Pigs were sacrificed after 1 and 6 months for histolo…
