A simple immunocytochemical method was standardized for the direct demonstration of mycobacterial antigen in cerebrospinal fluid (CSF) specimens of patients with tuberculous meningitis (TBM). CSF-cytospin smears were prepared from 22 patients with a clinical diagnosis of TBM and also from an equal number of patients with nontuberculous neurological diseases (disease control). Immunocytological ...
The early diagnosis of tuberculous meningitis (TBM) is very important. In this study, the efficiency of the polymerase chain reaction (PCR), one of the most reliable and sensitive DNA-based assays, was compared with conventional methods (acid-fast microscopy and culture) for the detection of M. tuberculosis in cerebrospinal fluid(CSF) specimens from patients suspected of TBM. Of the 29 CSF spec...
Uncertainty and doubt dominate all aspects of tuberculous meningitis (TBM). The variable natural history and accompanying clinical features of TBM hinders the diagnosis. ZiehlNeelsen staining lacks sensitivity and culture results are often insuYciently timely to aid clinical judgement. New rapid diagnostic methods are incompletely evaluated, and many are not suitable for laboratories in low inc...
Tubercular meningitis (TBM) can have varied early and delayed complications involving brain or spinal cord. Although syringomyelia can occur sometimes as a late complication of tubercular meningitis, its occurrence in early stages of TBM is very rare. There are only two published case reports of syringomyelia in acute stage of TBM. We report a patient with tubercular meningitis who developed sy...
یکی از مسائل حیاتی در تخمین هزینههای ساخت و زمان اجرای پروژههای تونلی، پیشبینی عملکرد ماشینهای حفاری مکانیزه تمام مقطع تونل (Tunnel Boring machine, TBM) است. عملکرد TBM بشدت وابسته به میزان نرخ نفوذ دستگاه است. هدف از پژوهش حاضر، بسط مدلی برای تخمین نرخ نفوذ TBM توسط رویکرد سطح پاسخ می باشد. تونل شماره سه کوینز واقع در نیویورک به عنوان مطالعه موردی انتخاب شده و مدل پیشنهادی با دادههای آن م...
ببهبود عملکرد ماشین حفار TBM در حفاری تونل همواره مورد توجه بوده است. در این مقاله به بررسی تاثیر تغییر تعدادی از دیسک-های TBM با ابزار خراشی بر پارامترهای عملیاتی تراست، گشتاور و نرخ نفوذ در خط 6 مترو تهران پرداخته شده است. بدین منظور مقادیر پارامترهای عملیاتی در بخش های مختلفی از خط 6، قبل و بعد از تغییر ابزار برشی مورد بررسی قرار گرفته است. نتایج نشان میدهد تغییر نوع ابزار برشی به طور میانگ...
Abstract Tunnel boring machine (TBM) operational data is mostly analysed with respect to that was recorded during the advance of TBM. Focusing on standstills a gripper TBM, we analyse rock loads were passively in cylinders small roof support shield. These are situated beneath TBM’s shield – extending it against mass non-advance periods. Equipped pressure sensors, they enable unique opportunity ...
Tuberculous cerebral vasculitis (TCV) is a catastrophic complication of tuberculous meningitis (TBM). We report herein the case of a 41-year-old woman with TBM who presented with a fever and headache for 2 weeks. Cerebrospinal fluid analysis revealed pleocytosis with lymphocytic predominance. On admission day 4, an anti-tuberculosis regimen and oral prednisolone were initiated; on day 30, she d...
We describe the Tactical Battle Manager (TBM), an intelligent agent that uses several integrated artificial intelligence techniques to control an autonomous unmanned aerial vehicle in simulated beyond-visual-range (BVR) air combat scenarios. The TBM incorporates goal reasoning, automated planning, opponent behavior recognition, state prediction, and discrepancy detection to operate in a real-ti...
In the context of human action recognition in video sequences, a temporal belief filter is presented. It allows to cope with human action disparity and low quality videos. The whole system of action recognition is based on the Transferable Belief Model (TBM) proposed by P. Smets. The TBM allows to explicitly model the doubt between actions. Furthermore, the TBM emphasizes the conflict which is ...
