residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...

OBJECTIVES To prospectively evaluate the impact of 3.0 T Cardiac MR imaging using dual-source parallel radiofrequency (RF) transmission with patient-adaptive B1 shimming compared with single-source RF transmission in the RF homogeneity, image contrast and image quality. METHODS The study was approved by the local institutional review board, and all subjects provided written informed consent. ...

RATIONALE Germinomas are sensitive to radiation therapy and chemotherapy; therefore, correct imaging diagnosis is crucial for them. However, the imaging findings of germinomas originating from off-midline regions displayed different patterns from those originating from midline areas. PATIENT CONCERNS The objective of this study is to describe the radiologic features of primary ectopic germino...

Abstract Coronal mass ejections (CMEs) that originate from pseudostreamers, which separate coronal holes of the same magnetic polarity, are characterized by a narrow (∼5°–30°), fan-shaped appearance in white-light coronagraph images. Despite this striking morphological similarity, wide variety underlying eruptions observed, including not only jets, but also larger-scale filament eruptions, foot...

Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...

mortality among subjects 65 and older with hemoglobin levels even in the “normal range,” is intriguing, in other studies2,3 confounding comorbid conditions accounted for most or all of the difference between anemic and nonanemic groups. Furthermore, even if 22% of the population were at risk for early demise because their hemoglobin levels were found to be low, it would remain to be shown that ...

This paper shows that polluters who underestimate environmental harm might invest excessively in promoting technological change in pollution control under environmental liability law. Neither strict liability nor negligence can prevent such a distortion. However, we define a second best due care standard under negligence that induces a welfare superior R&D equilibrium. If, on the other hand, po...

Settling an Old Debate In their article “Bantu expansion shows that habitat alters the route and pace of human dispersals,” Grollemund et al. (1) have accomplished more than just their stated intention: to identify the role of habitat in channeling the directions of the early Bantu farming settlement of the African equatorial rainforest. What is most important is that the authors essentially br...

The effect of different parameters including: nano silica content, curing temperature, type of hardener, and flash-off time on mechanical and optical properties of polyurethane PU based clearcoat was investigated via standard Taguchi L9 method. Dispersion of nano silica in the resultant nanocomposites was explored by scanning electron microscopy SEM. SEM images showed a fine dispersion through ...
