Long-Term Monitored Road Degradation Functions as a Tool to Increase Quality of Pavement Design

Interdiction problem as a tool to identify an effective budget allocation to quality improvement plans

In the face of budgetary limitations in organizations, identifying critical facilities for investing in quality improvement plans could be a sensible approach. In this paper, hierarchical facilities with specified covering radius are considered. If disruption happens to a facility, its covering radius will be decreased. For this problem, a bi-objective mathematical formulation is proposed. Crit...

Platelet Factor 3 Based-clotting Time Assay as a Quality Marker for Long-term Storage of Platelet Concentrates

Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...

The Long Road to Eradicate Rinderpest

Is Flexible Pavement Design on the Right Road?

The principles underlying current mechanistic–empirical pavement design methods for fully flexible pavements have changed little in the past 30 years. They generally use linear elastic theory to determine the permissible strain at critical locations in the pavement structure to safeguard the road against excessive fatigue and structural deformation. These criteria are calibrated using performan...

Applying Non-Contractual Methods and Quantitative Terms to Increase the Durability of Long-Term Natural Gas Sale Agreements

The success of long-term gas sales contracts is largely related to the ability of the seller and the buyer to adapt the terms of the contract to their conditions, infrastructure, facilities and market. If the buyer's demand changes from season to season and seasonally fluctuates, problems and complexities arise for the seller and he may need to provide the excess capacity to produce, refine and...
