Reconstructions of the (110) surface of rutile TiO2 (the dominant surface of this important mineral and catalyst) are investigated using the evolutionary approach, resolving previous controversies. Depending on thermodynamic conditions, four different stable reconstructions are observed for this surface. We confirm the recently proposed "Ti2O3-(1×2)" and "Ti2O-(1×2)" reconstructions and predict...

A marked bend in the Hawaiian-Emperor seamount chain supposedly resulted from a recent major reorganization of the plate-mantle system there 50 million years ago. Although alternative mantle-driven and plate-shifting hypotheses have been proposed, no contemporaneous circum-Pacific plate events have been identified. We report reconstructions for Australia and Antarctica that reveal a major plate...

A general, model-free, quantitative approach to the key morphological properties of a porous polymer monolith is presented. After 3D reconstruction, image-based analysis delivers detailed spatial and spatially correlated information on the structural heterogeneities in the void space and the polymer skeleton. Identified heterogeneities, which limit the monolith's performance in targeted applica...

We present a numerical image-formation model for investigating the influence of partial coherence, sample thickness and depth-of-focus on the accuracy of tomographic reconstructions in transmission x-ray microscopes. The model combines wave propagation through the object by finite difference techniques with Fourier methods. We include a ray-tracing model to analyse the origin of detrimental str...

Penile and urethral reconstructive surgical procedures are used to treat a variety of urologic diagnoses. Urethral stricture disease can lead to progressive lower urinary tract symptoms and may require multiple surgical procedures to improve patient's symptoms. Male stress urinary incontinence is associated with intrinsic sphincter deficiency oftentimes associated with radical prostatectomy. Me...

BACKGROUND Fournier's gangrene is an acute and potentially lethal necrotising fasciitis that involves the scrotum and perineum. This disease can result in the loss of skin and soft tissue. To repair the scrotal and perineal defects remains a surgical challenge. METHODS Between January 2000 and December 2008, 50 patients were admitted to our hospital with a diagnosis of Fournier's gangrene. We...

Facial reconstruction is one of the most challenging problems faced by a reconstructive surgeon. We present a case of complex facial reconstruction with a composite trauma to the nose resulting in near total loss of skin and lining along with complete loss of left eyebrow with exposed frontal bone and partial loss of the left eyelid. We combined a temporoparietal fascial flap for reconstruction...

background: cardiovascular disease is an important non-obstetric cause of maternal and fetal /neonatal morbidity and mortality during pregnancy. for a pregnant woman with cardiac disease, the potential inability of the maternal cardiovascular system to contend with normal pregnancy-induced physiologic changes may produce deleterious effects on both mother and fetus. to determine the most freque...

conclusions comparing the serum lactate level before operation and 24 hours after the operation showed that the number of received blood units had a significant effect on serum lactate. we found no significant effect for blood storage duration; however, the number of given blood units was more significant. patients and methods in a cross-sectional study, 228 patients referred to three hospitals...
