Introduction: Chondrogenesis occurring in soft callus is one of the major histological processes in the healing of fractures, though the molecular and cellular events, which regulate this process, have not been fully elucidated. In the present study, using a standardized rat closed fracture model, we examined the spatial and temporal gene expression for cartilage-related proteins and extensivel...

In this paper, we introduce a variant of the orienteering problem in which travel and service times are stochastic. If a delivery commitment is made to a customer and is completed by the end of the day, a reward is received, but if a commitment is made and not completed, a penalty is incurred. This problem reflects the challenges of a company who, on a given day, may have more customers than it...

PURPOSE To investigate tibial tunnel widening and knee instability after ACL reconstruction with hamstring autograft or irradiated soft tissue allograft. METHODS Eight-two patients were divided into two groups: autograft group and allograft group. Radiographic and clinical evaluations were performed. RESULTS Seventy patients were followed up with median of 36.3 months (range 36-38 months). ...

We present high-resolution observations of an extremely metal-poor damped Lyα system (DLA), at zabs = 2.340 0972 in the spectrum of the QSO J0035−0918, exhibiting an abundance pattern consistent with model predictions for the supernova yields of Population III stars. Specifically, this DLA has [Fe/H] −3, shows a clear ‘odd–even’ effect, and is C-rich with [C/Fe] = +1.53, a factor of ∼20 greater...

The increasing rate of technology growth has resulted in decrease in cost of information. These technologies are helpful in coordinating the activities resulting in effective management of the supply chain. Literature shows that the use of Information Technology (IT) plays an important role in managing the processes of SCM. This has resulted in increasing use of IT in SCM. The computerization o...
