a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis

the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.

study of the spatial variability of infiltration characteristics is essential to estimating infiltration parameters on a local scale. the objectives of the present study were to scale the parameters of a philip two-term model for infiltration and survey the variability of infiltration characteristics geostatistically using wastewater in the bajgah catchment. infiltration was measured at 30 poin...

Fiber metal laminates (FMLs) have been successfully manufactured by the vacuum assisted resin transfer molding (VARTM) process developed at NASA Langley Research Center. A flow visualization fixture of the FML, VARTM process was constructed and used to observe the resin infiltration process. Results of the flow visualization experiments are reported and compared with the predictions of a VARTM ...

We propose a new technique to perform precise selective infiltration of an air hole in the photonic crystal fiber (PCF). To carry out the infiltration process, the end face of the PCF is covered by a mask, which is fabricated by femtosecond laser inscription from the lateral direction. This proposed method overcomes the conventional limitation of maximum mask thickness. An analytical model is f...

Two studies examined determinants of self-infiltration (i.e., false self-attribution of externally controlled goals or activities). According to Personality Systems Interactions (PSI) theory, a sad mood was expected to reduce access to integrated self-representations and lead to self-infiltration for participants who have an impaired ability to cope with negative affect (i.e., state-oriented pa...

BACKGROUND Infiltration is a key process in determining the water balance, but so far effects of earthworms, soil texture, plant species diversity and their interaction on infiltration capacity have not been studied. METHODOLOGY/PRINCIPAL FINDINGS We measured infiltration capacity in subplots with ambient and reduced earthworm density nested in plots of different plant species (1, 4, and 16 s...

Solid Freeform Fabrication processes such as three-dimensional printing (3DP) and selective laser sintering (SLS) produce porous parts that must be densified. New steel infiltration methods can produce parts of standard alloy compositions with properties comparable to wrought materials. However, the infiltration process introduces dimensional errors due to both shrinkage and creep—particularly ...

abstract- to study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in badjgah, fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). in each pl...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...
