در حالی که آسیب پذیری نرم افزار یکی از مشکلات مهم امنیتی در سازمانها به شمار می رود، خودکارسازی مدیریت آسیب پذیری نرم افزار و به تبع آن استفاده از استانداردهای توصیف آسیب پذیری های نرم افزاری بیشتر مورد استقبال قرار می گیرد. امروزه استانداردهای متعددی برای توصیف آسیب پذیری های نرم افزاری در جهان وجود دارند. از جمله این استانداردها می توان به cve، oval، xccdf، avdl و vuxml اشاره کرد. این استاندا...
The aim of the present microtomographic study was to investigate the quality of root canal filling and the voids formation in canals of extracted teeth instrumented with a simultaneous technique and filled with two different methods. Twenty-four single-rooted teeth were assigned to two experimental groups (no. = 12); canals were shaped with NiTi rotary files, irrigated with NaOCl and filled eit...
Olecranon and coronoid fossae of lower end of humerus separated by thin plate of bony septum (0.5 to 1 mm thickness). Sometimes the bony septum may shows perforated clear foramen is referred as Supratrochlear foramen (STF). STF is always associated with narrow medullary canal, in that case it is not easy to perform intramedullary fixation of the humerus in traumatic injuries and pathologic frac...
This study describes the mucosa-associated lymphoid tissue (MALT) in odontocetes from the Brazilian coast and freshwater systems. Seven species were evaluated and tissue samples were analyzed by light, scanning and transmission electron microscopy, and immunohistochemistry. Laryngeal tonsil was a palpable oval mass located in the larynx, composed of a lymphoepithelial complex. Dense collections...
The membranous labyrinth is contained within the bony labyrinth and surrounded by perilymph. The only two 'potentially yielding' parts of the otherwise solid bony labyrinth are the oval and round windows, which by their relative movements, pressure differentials and resilience are responsible for all the functions attributed to the inner ear. In pathologies, such as trauma, infection or occasio...
Background/Aim: To evaluate void volumes in oval-shaped root canals obturated with three different obturation systems using microcomputed tomography (micro-CT). Material and Methods: Twenty-four distal roots of mandibular molar teeth were prepared randomly divided into groups (n = 8 each group). The single cone (SC), GuttaCore (GC), warm vertical compaction (WVC) techniques. Each specimen was s...
Perilymph fistula (PLF) is defined as a leak of perilymph at the oval or round window. It excludes other conditions with "fistula" tests due to a dehiscent semi circular canal from cholesteatoma and the superior canal dehiscence syndrome. It was first recognized in the early days of stapedectomy as causing disequilibrium and balance problems before sealing of the stapedectomy with natural tissu...
