The conventional zeta inverter has been used for single-phase grid-connected applications.However, it has high switching losses to operate at high switching frequency in the continuous conduction mode (CCM).To address this drawback, this paper suggests a high-efficiency zeta inverter using active clamp and synchronous rectification techniques.The p
Background: Human Papilloma Virus has been considered as the precursor of flat lesions in the cervical epithelium which develops Cervix uterine cancer.Objectives: to analyze risk factors associated to infections due to human papilloma virus.Method: An ambispective, descriptive study was carried out from January 2003 to January 2004, taking 60 patie
The current understanding of UK Middle Jurassic pterosaur taxonomy is under-developed, leading to it being previously considered a time of low diversity.This is despite the presence of a productive but under-studied pterosaur-bearing horizon extending over parts of Oxfordshire and Gloucestershire.This unit, informally called the Stonesfield Slate,
Background: Etiological understanding is the corner stone in the management of skeletal deformities.Methods: Multi-centre study of patients with deformities in connection with ball stop diverse etiological backgrounds.We aimed to study four patients (one boy and three girls) with variable axial and appendicular deformities in connection with a vani
