The aim was to compare fear of re-injury, patient reported function, static and dynamic tibial translation and muscle strength assessed before and 5 weeks after an anterior cruciate ligament (ACL) reconstruction between individuals who sustained a subsequent ACL graft rupture or a contralateral ACL injury within 5 years after the reconstruction, and individuals with no subsequent injury. Ninete...

introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...

Dynamic optimizers have shown to improve performance and power efficiency of single-threaded applications. Multithreaded applications running on CMP, SMP and cc-NUMA systems also exhibit opportunities for dynamic binary optimization. Existing dynamic optimizers lack efficient monitoring schemes for multiple threads to support appropriate thread specific or system-wide optimization for a collect...

Existing LES methods face three basic problems: a huge variety of LES models are currently applied, dynamic LES methods are either very expensive or have to be combined with ow-dependent empirical stabilization techniques, and the cost of LES for wall-bounded ow simulations are way too high for most applications. Solutions for these three problems can be developed by deriving non-dynamic, dynam...

The problem of routing virtual circuits according t o dynamic probabilities in virtual circuit packe t switched networks is considered. Queueing network models a r e introduced and performance measures a re defined. A decentralized asynchronous adaptive routing methodology, based on learning automata theory is presented. Every node in the network has a stochastic learning automaton as a router ...

We consider a system in which multiple-items are transferred from a warehouse or a plant to a retailer through identical capacitated vehicles, or freight wagons. Any mixture of the items may be loaded on a vehicle. The retailer is facing dynamic deterministic demand for several items, over a finite planning horizon. A vehicle incurs a fixed cost for each trip made from the warehouse to the reta...
