INTRODUCTION The costs associated with patients discharged with isolated clinician-elicited persistent midline tenderness and negative computed tomography (CT) findings have not been reported. Our aim was to determine the association of acute and post-acute patient and injury characteristics with health resource costs in such patients following road trauma. METHODS In a prospective cohort stu...

The Blue-throated Macaw (Ara glaucogularis) is a Critically Endangered species endemic to the Llanos de Moxos ecosystem of Beni, Bolivia. To aid conservation northwestern population that utilizes Barba Azul Nature Reserve during non-breeding season, we set out learn sites where these birds breed using satellite telemetry. We describe preliminary tests conducted on captive (at Loro Parque Founda...

The aim of this study is to assess the number of workers potentially at risk of bladder cancer in Italy. A detailed list of codes of economic activities entailing bladder cancer risk was developed on the basis of the excess risk resulting from two different pooled analysis (separately for men and women) in Europe. Firms and the number of blue-collars potentially at risk were selected from the I...

In this paper, we obtain analogues of Jørgensen’s inequality for non-elementary groups of isometries of quaternionic hyperbolic n-space generated by two elements, one of which is loxodromic. Our result gives some improvement over earlier results of Kim [10] and Markham [15]. These results also apply to complex hyperbolic space and give improvements on results of Jiang, Kamiya and Parker [7]. As...

HUA LI. Countermeasures against Scour at Bridge Abutments (Under the direction of Dr. BRIAN D. BARKDOLL) Scour at bridge abutments can cause damage or failure of bridges and result in excessive repairs, loss of accessibility, or even death. To mitigate abutment scour, both clear-water and live-bed laboratory experiments in a compound channel were performed using parallel walls and spur dikes as...

We present a new meshing algorithm to mesh an arbitrary piecewise-linear complex in three dimensions. The algorithm achieves an O(n log ∆ + m) runtime where n, m, and ∆ are the input size, the output size, and spread respectively. This runtime represents the first non-trivial runtime guarantee for this class of input. The new algorithm extends prior work on runtime-efficient meshing by allowing...

River dynamics and sediment transport play an important role in river bed morphology. Building a bridge pier along the alters cross-section of causes change flow processes. These changes are mainly responsible for scour. In this paper, usage collars to reduce scour around circular piers has been investigated. The with different diameters depth positions have studied using previous data addition...
