Thin films of Bi(1-x)Sr x FeO3 (X = 0.00, 0.05, 0.10, 0.20, and 0.30) are synthesized on ultra-cleaned glass substrates by simple spray pyrolysis method at 550 °C. The crystal structures of the thin films are investigated by x-ray diffraction (XRD). The Rietveld refinement data for all the thin films are confirmed a single-phase ABO3 type of rhombohedral structure belonging to the R3c space group. The field emission scanning electron microscopy (FESEM) analysis reveals the size of grains from hexagonal to spherical shape with the addition of Sr doping. The vibrational modes are studied by Raman spectroscopy. The x-ray photoelectron spectroscopy (XPS) analysis unravels the influence of Sr2+ in the creation of Fe2+ defects and oxygen vacancies. The room temperature magnetic measurements of the thin films are carried out within a magnetic field range of ±10 kOe. Magnetic hysteresis loop confirms a significant increase in magnetization in Sr modified bismuth ferrite thin films. Tariquidar The composition i.e. X = 0.20 shows maximum enhancement of magnetic properties with saturation and Remanent magnetization values of 5.99 emu g-1 and 1.77 emu g-1, respectively.Background We aimed to assess the predictive value of the absolute and relative intact parathormone (iPTH) decline levels as reliable markers of postoperative hypocalcemia. Materials & methods iPTH levels were measured 4 h after surgery and the following morning after surgery (postoperative day 1). iPTH, absolute iPTH decline (ΔPTH) and relative iPTH decline (ΔPTH%) were calculated and correlated with symptomatic hypocalcemia. Results Of the 95 patients, 20% of patients (n = 19) developed symptomatic hypocalcemia. The ΔPTH (U = 206; p less then 0.001) and ΔPTH% (U = 127; p less then 0.001) were significantly higher in patients with symptomatic hypocalcemia. A ΔPTH% of 20% (sensitivity of 84%; specificity of 91%); and an absolute iPTH decline of 3.75 pg/ml (sensitivity of 74%; specificity of 87%) were highly predictive of symptomatic hypocalcemia. Conclusion Postoperative ΔPTH and ΔPTH% have the potential to be predictors of symptomatic hypocalcemia following thyroidectomy and could facilitate a safe early discharge. Intubation of children in the emergency setting is a high-risk, low incidence event. Standardisation of clinical practice has been hampered by a lack of high-quality evidence to support one technique over another. The aim of the present study is to determine clinician preference in intubation practice of children in EDs and ICUs in Australia and New Zealand to provide baseline information to allow future targeted research focused on improving the safety and efficacy of paediatric emergency airway management. The present study was a voluntary questionnaire undertaken by medical staff at registrar level or above in EDs and ICUs associated with the Paediatric Research in Emergency Departments International Collaborative (PREDICT) and Australia and New Zealand Intensive Care Society Paediatric Study Group (ANZICS PSG) research networks. Respondents reported on their individual intubation practices, with a focus on pre-oxygenation and apnoeic oxygenation techniques, and the use of video laryngoscopy. A total of 502 clinicians were invited to complete the survey between May and October 2018 with 336 (66.9%) responded. There was marked variation in practice between ED clinicians and ICU clinicians in the techniques used for pre-oxygenation, the frequency of use of apnoeic oxygenation and the reported use of video laryngoscopy. Within Australia and New Zealand there is considerable variation in paediatric emergency airway clinical practice, in particular with respect to pre-oxygenation, apnoeic oxygenation and use of video laryngoscopy. Definitive clinical trials are required to best inform clinical practice in this area. Within Australia and New Zealand there is considerable variation in paediatric emergency airway
