BACKGROUND With high short-term mortality and substantial excess morbidity among survivors, tuberculous meningitis (TBM) is the most severe manifestation of extra-pulmonary tuberculosis (TB). The objective of this study was to assess the long-term mortality and causes of death in a TBM patient population compared to the background population. METHODS A nationwide cohort study was conducted en...

One of the core research areas of the “Laboratoire de Météorologie Physique” (LaMP) at the “Observatoire de Physique du Globe de Clermont-Ferrand” (OPGC) is the study of clouds and precipitations, and their corresponding microphysical processes, both from the modeling and the observational point of vues. In order to improve its observation capabilities of precipitations, LaMP/OPGC has entered a...

ECM emerges out to be one of the major non conventional machining techniques based on Faraday‟s laws of electrolysis, highly efficient due to its zero tool wear characteristic. Occurrence of passivation is the major problem faced in ECM. In the present work, study of the flow pattern of electrolyte has been performed so that, the machining variable distribution can be predicted accurately thus ...

avid Klotzkin he University of Cincinnati epartment of Electrical and Computer Engineering and Computer Science .O. Box 210030 incinnati, Ohio 45221-0030 Abstract. Modulating retroreflectors MRRs couple passive optical retroreflectors with electro-optic modulators to allow free-space optical communication with a laser and pointing-acquisition-tracking system required on only one end of the link...

Electrical discharge machining (EDM) is a non conventional manufacturing process which is used for shaping hard metals and forming deep complex shaped profiles by arc erosion in all kinds of electro-conductive materials. The objective of this paper is to study the influence of process parameters and electrode shape configuration on the machining characteristics such as surface quality, material...

The utilization of TiB2 particles reinforced aluminum (Al6063) metal matrix composite materials in many different engineering fields has undergone a tremendous increase. Accordingly, the need of accurate machining of composites has increased enormously; an attempt has been made to assess the factors influencing surface roughness and material removal rate on machining the composite. The orthogon...

Chemical–mechanical polishing (CMP) is a planarization process that utilizes chemical reactions and mechanical material removal using abrasive particles. With the increasing integration of semiconductor devices, CMP gaining importance in manufacturing. Abrasive-free (AF-CMP) uses solutions do not contain particles to reduce scratches improve capabilities. However, because AF-CMP does use for re...

CNC turning is widely used as a manufacturing process through which unwanted material is removed to get the high degree of surface rough. In this research article, Taguchi technique was coupled with grey relation analysis (GRA) to optimize the turning parameters for simultaneous improvement of productivity, average surface roughness (Ra), and root mean square roughness (Rq).Taguchi technique L2...

We construct integral operators Rr and Hr on a regular q-pseudoconcave CR manifold M such that f = ∂̄MRr(f) + Rr+1(∂̄Mf) +Hr(f), for f ∈ C (0,r) (M) and prove sharp estimates in a special Lipschitz scale.
