A novel single-stage push–pull electronic ballast with high input power factor is presented in this paper. The proposed electronic ballast combines the front-end power-factor corrector and push–pull converter into a single-stage converter. Compared to the single-stage class-D electronic ballast, the proposed circuit does not require an isolated driver. The control of the circuit is easier and t...

PURPOSE To determine the clinical, pathologic, and molecular effects of neoadjuvant docetaxel chemotherapy in high-risk localized prostate cancer. EXPERIMENTAL DESIGN Patients with biopsy Gleason scores of 8 to 10, serum prostate-specific antigen levels >20 ng/mL, and/or clinical stage T3 disease received weekly docetaxel (36 mg/m2) for 6 months, followed by radical prostatectomy, and were mo...

CONTEXT Correct assessment of tumour stage is crucial for prostate cancer (PCa) management. OBJECTIVE To assess the diagnostic accuracy of magnetic resonance imaging (MRI) for local PCa staging and explore the influence of different imaging protocols. EVIDENCE ACQUISITION We searched the PubMed, Embase, and Cochrane databases from 2000 up to August 2014. We included studies that used MRI fo...

The scope of this work is the complete re-organization of production flow according to the Lean Thinking philosophy for the industrial applications. The complete re-organization implementation of material flow management has been performed through the supermarket sizing which replenishment kanban logic has been adopted. To implement this strategy the goal is to achieve "Interdependent connected...

Drawing on both my own personal experience and that of many colleagues and pupils, I shall describe three kinds of reactions to stage fright. The first is the primarily mental reaction of derealization, which involves feeling cut off from fear and decreasing body awareness. The second and third reactions to stage fright involve (a) increased and (b) decreased muscle tonus and their associated b...

AIMS AND OBJECTIVES The aim of this study is to find easier way of home care while obviating the colostomy before single stage pull through operation. MATERIALS AND METHODS From August 2005 to December 2006, eight cases of neonatal Hirschsprung disease were treated. Mean age 4.5 (2-6) day/old with absent anorectal inhibitory reflex, rectosigmiod disease in Barium enema, positive Acetylcholine...

INTRODUCTION Obstructive parotid disease often causes significant discomfort and negative quality of life in patients who suffer from this condition. The disorder presents as intermittent, recurrent swelling and tenderness of the parotid gland made worse during meals. Salivary duct obstruction results in stagnation of saliva, often leading to recurrent bouts of parotitis. Although salivary ston...
