Computational fluid dynamics simulations have demonstrated flow problems within the helium flow path in the current US DCLL ITER test blanket module design. New geometry for the helium flow path has been designed that will improve flow evenness and simplify the overall helium flow path within the test blanket module while maintaining the overall test blanket module geometry. Global changes to t...

With widespread increasing applications of mechanized tunneling in almost all ground conditions, prediction of tunnel boring machine (TBM) performance is required for time planning, cost control and choice of excavation method in order to make tunneling economical. Penetration rate is a principal measure of full-face TBM performance and is used to evaluate the feasibility of the machine and pre...

BACKGROUND A modified clinical presentation of tuberculous meningitis (TBM) in children vaccinated with BCG has been described in the literature. However, most reports are old and not based on actual comparisons and tests of significance. Also, neuroimaging features were not compared. With large scale BCG coverage, it becomes pertinent to describe the "modified" presentation and identify any si...

Introduction:Tuberculous meningitis (TBM) is the most common and belligerent form of CNS TB.Prompt definitive diagnosis of TBM is arduous due to tedious microbiological procedures. This study was conducted to evaluate the neuroradiological findings in patients with TBM as a modality forearly diagnoses and predicting prognosis. Materials and methods: A successive series of 100 patients diagnosed...

BACKGROUND A number of reports have described the presence of tuberculosis (TB) in neuromyelitis optica (NMO) patients. However, a definite association between the two conditions has not been conclusively demonstrated. METHODS To investigate the association between NMO and TB in a Chinese population, we performed a retrospective review of hospital records of NMO patients, control patients and...

Background Tuberculous meningitis (TBM) is the most severe form of tuberculosis. Co-infection with HIV increases the risk of developing TBM, complicates treatment, and substantially worsens outcome. Whether corticosteroids confer a survival benefit in HIV-infected patients with TBM remains uncertain. Hepatitis is the most common drug-induced serious adverse event associated with anti-tuberculos...

tuberculous meningitis (tbm) and acute bacterial meningitis (abm) cause substantial mortality and morbidity in both children and adults. identification of poor prognostic factors at patient's admission could prepare physicians for more aggressive monitoring of patients with meningitis. the objective of this study was to determine the predictive value of neurological features to differentiate ab...

The development of underground spaces in urban centers has attracted significant research attention. Typical excavation methods for areas include the New Austrian tunneling method (NATM) and tunnel boring machine (TBM). NATM is superior terms ease construction economic efficiency; however, vibration noise are often cited as major complaints. In addition to their high initial cost, TBMs require ...

Tuberculosis (TB) can involve any organ system in the body. Extrapulmonary involvement can occur in isolation or along with a pulmonary focus as in the case of patients with disseminated tuberculosis. Tuberculosis meningitis (TBM) is the most severe form of extrapulmonary tuberculosis. TBM a medical emergency, is still a major cause of serious illness in many parts of the world. TBM remains dif...

one of the most important parameters used for determining the performance of tunnel boring machines (tbms) is their penetration rate. the parameters affecting the penetration rate can be divided in two categories. the first category is the controllable parameters such as the tbm technical characteristics, and type and geometry of the tunnel, and the second one is the uncontrollable parameters s...
