Solar and wind energy systems are omnipresent, freely available, environmental friendly, and they are considered as promising power generating sources due to their availability and topological advantages for local power generations. Hybrid solar–wind energy systems, uses two renewable energy sources, allow improving the system efficiency and power(More)
BACKGROUND Spine surgery is widely accepted as an effective management for patients with lumbar disc herniation; however, the factors influencing intraoperative procedure and prognosis are not fully understood. The present study was aimed to identify the factors influencing intraoperative blood loss, postoperative drainage volume, and recovery in patients(More)
BACKGROUND Postoperative delirium is a common complication following various operative procedures with an incidence rate of 10-77 %. AIM To analyze various risk factors for postoperative delirium after spine surgery in the middle- and old-aged patients. METHODS This study retrospectively reviewed 451 patients (226 males and 225 females, an average age(More)
STUDY DESIGN A prospective study using magnetic resonance imaging on a consecutive cohort of patients with cervical vertigo. OBJECTIVE To quantitatively investigate the cerebral blood flow (CBF) changes associated with cervical vertigo by using 3-dimensional pseudocontinuous arterial spin labeling. SUMMARY OF BACKGROUND DATA Previous studies reported(More)
To investigate the cervical spinal canal diameters variance under positional MRI, and also the relationship between cervical canal diameter variance rate and grade of degeneration. From January 2013 to January 2015, a consecutive of 273 symptomatic patients (166 males and 207 females) with an average age of 44.6 years (range 21–89 years) underwent(More)
OBJECTIVE To explore the effects of autotransfusion on intraoperative blood loss and postoperative drainage volume in posterior lumbar spinal surgery. METHODS From June 2010 to January 2012, a total of 183 patients with lumbar disease were enrolled. There were 74 males and 109 females with an average age of 56.6 (31-81) years. There were lumbar disc(More)
Phage PH357, a novel lytic Pseudoalteromonas lipolytica phage belonging to the Myoviridae family was isolated from the Yangtze River estuary. The microbiological characterization demonstrated that phage PH357 is stable from −20 to 60 °C and the optimal pH 7. The one-step growth curve showed a latent period of 20 min, a rise period of 20 min, and the average(More)
Renewable energy has attracted the interests of researchers all around the world. The major challenge is to combine various existing sources in a single model so as to extract the usefulness of each of them while complementing each others weaknesses. This paper proposes a method to integrate solar photovoltaic system, wind turbine system and diesel(More)
