“Nanofluids containing graphene oxide nanosheets have substantially higher thermal conductivities than the base fluids. The thermal conductivity enhancement ratios with the loading 5.0 vol % are up to 30.2%, 62.3%, and 76.8%, when the base fluids
are distilled water, propyl glycol and liquid paraffin, respectively. The enhancement ratios of the nanofluids are almost constant with the tested temperature varying, and they are reduced with the increasing thermal conductivity of the base fluids. Heat transport along the graphene oxide plane is proposed to be the major contributions LGX818 price to the increase in the thermal conductivity. (c) 2010 American Institute of Physics.

“Objectives. The aim was to investigate magnetic resonance (MR) and computerized tomography (CT) images and compare MR and CT image features of postoperative maxillary cysts (POMC).
Study design. We retrospectively evaluated MR and CT images of 7 POMC patients. Number of the cysts, border, bone expansion, CT value, signal intensity, and contrast enhancement were observed.
Results.
On CT images, 15 cysts were detected. Fourteen cysts showed smooth border. Bone expansion was found in 10 cysts. Mean CT value of each cyst ranged from 23 to 50 Hounsfield units. On MR images, 18 cysts were detected. Twelve cysts showed smooth border. Bone expansion was not observed. selleck chemicals Most cysts showed intermediate signal intensity on T1-weighted images, and
high or nonhomogeneous intermediate/high signal intensity on T2-weighted images with the fat suppression technique. No cyst showed contrast enhancement in both examinations.
Conclusion. The CT images revealed bony information, and the MR images clearly demonstrated border of POMC. POMC should be evaluated with both CT and MR imaging. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 107: e38-e44)”
“Objective-To define a method Stattic cost for the basilar sesamoidean approach (BSA) to the digital flexor tendon sheath (DFTS) in horses and compare it with the axial sesamoidean approach (ASA) for DFTS synoviocentesis and injection.
Design-Evaluation study.
Animals-12 healthy adult mares without evidence of abnormalities related to the lower limbs.
Procedures-Each horse had 1 forelimb and 1 hind limb assigned to each DFTS approach (basilar vs axial, relative to the proximal sesamoid bones) in a Latin square design. The order of horses and of limb injection for each horse was randomly selected. All procedures were performed in standing sedated horses.The number of attempts to place a needle in the DFTS, presence of synovial fluid in the needle hub, time for DFTS injection, and number of accurate injections of sterile contrast material into the DFTS (evaluated by means of radiography) were compared between methods.
