UNLABELLED We aimed to validate the accuracy of a new automated myocardial perfusion SPECT quantification based on normal limits for detection and sizing of infarcts, using delayed-enhancement MRI (DE-MRI) as a gold standard. METHODS Eighty-two immediate (201)Tl rest scans and 26 (201)Tl delayed redistribution scans were compared with resting DE-MRI scans acquired within 24 h of SPECT acquisi...

This paper presents a case study of decade-long technology-enabled teacher professional development (TPD) initiative for government-run school teachers in India. The TPD aimed at capacitating integrating project-based or constructivist learning with technology curriculum and pedagogy. Teachers are central to the teaching–learning processes, hence them leverage digital technologies confidently i...

BACKGROUND AND AIMS The need for transpapillary drainage (TPD) in patients undergoing transmural drainage (TMD) of pancreatic fluid collections (PFCs) remains unclear. The aims of this study were to compare treatment outcomes between patients with pancreatic pseudocysts undergoing TMD versus combined (TMD and TPD) drainage (CD) and to identify predictors of symptomatic and radiologic resolution...

Opportunity The United State’s natural resource base of soils and climate has made it one of world’s leading producers of food crops. Its resource base also has the potential to grow large quantities of biomass for the manufacture of biobased products, as demonstrated by the fact that the U.S. is the world’s leading manufacturer of grainbased ethanol. To fully develop this potential, manufactur...

The surface chemistry of single crystal barium titanate (BaTiO3) has been studied using temperature programmed desorption (TPD). TPD measurements were performed with several probe molecules, including methanol and carbon dioxide. The role of oxygen vacancies in the adsorption and reaction of these molecules was examined by annealing the crystal under oxidizing or reducing conditions prior to pe...

This study aimed to assess the effects of bone-borne and tooth-borne surgically assisted rapid maxillary expansion on the volumes of the nose and nasal airway 2 yr after maxillary expansion. This prospective cohort study included 32 patients with transverse maxillary hypoplasia. Expansion was performed with a tooth-borne distractor (Hyrax) in 19 patients and with a bone-borne distractor [transp...

In this work, microwave synthesis, chemical, optical and electrochemical characterization of three small organic molecules, TPA-TPD, TPA-PT-TPD and TPA-TT-TPD with donor-acceptor structure and their use in organic photovoltaic cells are reported. For the synthesis, 5-(2-ethylhexyl)-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione was used as electron withdrawing fragment while the triphenylamine was used ...

Wehave undertaken a detailed investigation of the adsorption, desorption and thermal processing of the astrobiologically significant isomers glycolaldehyde, acetic acid andmethyl formate. Here, we present the results of laboratory infrared and temperature programmed desorption (TPD) studies of the three isomers from model interstellar ices adsorbed on a carbonaceous dust grain analogue surface....

Introduction The reactivity behavior of chars and carbons under reaction with oxygen agents has been the focus of many studies due to its practical applications in industry. Characterization of the oxygen complexes in the char surface is very important because its relation with mechanism of gasification and combustion reactions. Studies using transient kinetic have shown that in the char-CO2 an...
