A clock generator using a fast-locking frequency-locked loop (FLL)-based RC oscillator and delta-sigma fractional dividers (FDIVs) to generate programmable temperature-insensitive output frequencies is presented. Successive approximation register (SAR) logic used speed up the locking of FLL, truncation error cancellation (TEC) performed in FDIVs reduce delta-sigma-induced jitter. prototype fabr...

Introduction: Infants born with congenital anomalies demand individualized nutritional evaluations and recommendations. The anatomical changes of neonatal surgical diseases create specific physiological constraints.Patients with different congenital anomalies have different nutritional support needs. It is essential to know the exact physiology of these anomalies in order to be able to manage a...

Introduction: Childhood obesity is a growing global health problem, but in the view of medical ethics, obesity management in children is associated with challenges. Method and materials: This study is a comprehensive review in English (Cochrane Library, and PubMed) and Persian literature which pointed to the ethical aspects of pediatrics obesity management with content analysis. Results: In t...

AIM To estimate the potential cost effectiveness of photodynamic therapy (PDT) with verteporfin in the UK setting. METHODS Using data from a variety of sources a Markov model was built to produce estimates of the cost effectiveness (incremental cost per quality adjusted life year (QALY) and incremental cost per vision year gained) of PDT for two cohorts of patients (one with starting visual a...

In this study, renewable and sustainable biofuel production from waste cooking oil its blends with diesel fuel are investigated in terms of specific properties. The named “Renewable Biofuel (RBF) 20” (20% biofuel–80% diesel), 50” (50% biofuel–50% 100” (100% biofuel). acid number, flash point, viscosity, cloud density, pour point properties the new Renewable Biofuels experimentally obtained comp...
