In agricultural watersheds, human interventions such as channel straightening have disrupted the hydrologic connectivity between headwater streams and their riparian environment thus undermined ecological services provided by these small streams. Knowledge of immediate (shallow groundwater in historical floodplain on adjacent hillslopes) human-impacted settings is critical for understanding res...

moebius syndrome is a rare congenital disorder of the facial and abducens nerve. other cranial nerves may be involved, such as v, ix and xii. several central nervous system anomalies including hypoplastic or dysplastic brain stem, straightening of the fourth ventricle floor, focal necrosis and calcifications of cranial nerve nuclei have been reported in association with moebius syndrome, but we...

An 87-year-old female presented with complaints of intermittent severe right renal colic. CT imaging demonstrated a ureterosciatic hernia and moderate hydronephrosis proximal to the portion of the ureter that was herniated through the sciatic foramen. A retrograde pyelogram demonstrated a transition point in the ureter at the location of the hernia. A ureteral stent was placed resulting in stra...

Small bowel angioedema induced by angiotensin converting enzyme (ACE) inhibitors is a rare and often-unrecog- nized condition that presents with transient abdominal pain, nausea and vomiting. We report a case diagnosed in a 36 year-old female. Ultrasound and CT showed segmental small bowel wall thickening and straightening associated with marked submucosal edema and ascites. Laboratory tests on...

We study a monoid associated to complex semisimple Lie algebras, called the quantic monoid. Its monoid ring is shown to be isomorphic to a degenerate quantized enveloping algebra. Moreover, we provide normal forms and a straightening algorithm for this monoid. All these results are proved by a realization in terms of representations of quivers, namely as the monoid of generic extensions of a qu...

We continue the study [2] on sheaves of rings on finite posets. We present examples where the ring of global sections coincide with toric faces rings, quotients of a polynomial ring by a monomial ideal and algebras with straightening laws. We prove a rank-selection theorem which generalizes the well-known rank-selection theorem of Stanley–Reisner rings. Finally, we determine an explicit present...

Ceramic veneers are considered a conservative solution for patients requiring improvement of the shape, color, or position of their anterior teeth. Ceramic veneers have been extensively and successfully used to mask intrinsic staining, to give the appearance of straightening, and to correct minor malformations of anterior teeth without the removal of substantial amounts of sound tooth substance...
