Global warming on planet Earth results from the high emission of greenhouse gases, especially CO2. The Portland cement industry releases amounts CO2 and is responsible for about 5-8% total emissions. Efforts have been made to look alternative cementless binders mitigate impact environment. Geopolymers are one highlighted alternatives can be obtained reaction any aluminosilicate material with an...

The adoption by Medicare in 1983 of prospective payment using diagnosis-related groups (DRGs) has stimulated research to develop case-mix grouping schemes that more accurately predict resource consumption by patients. In this article, the authors explore a new method designed to improve case-mix classification for newborns through the use of birth weight in combination with DRGs to adjust the u...

OBJECTIVE To assess the validity of case mix adjustment methods used to derive standardised mortality ratios for hospitals, by examining the consistency of relations between risk factors and mortality across hospitals. DESIGN Retrospective analysis of routinely collected hospital data comparing observed deaths with deaths predicted by the Dr Foster Unit case mix method. SETTING Four acute N...

The use of waste materials in road construction is becoming widely spread due to economic and environmental needs. Construction demolition mining residues have been studied for a long time. However, the fine materials, mainly from mine tailing residue, still complex, as they can be used inert into mix or become reactive agent geopolymer mixes. In present paper, an experimental application basal...

OBJECTIVE(S) To estimate the costs of public-sector abortion provision in South Africa and to explore the potential for expanding access at reduced cost by changing the mix of technologies used. STUDY DESIGN We conducted a budget impact analysis using public sector abortion statistics and published cost data. We estimated the total costs to the public health service over 10 years, starting in...

Data envelopment analysis (DEA) is a linear programming based non-parametric technique for evaluating the relative efficiency of homogeneous decision making units (DMUs) on the basis of multiple inputs and multiple outputs. There exist radial and non-radial models in DEA. Radial models only deal with proportional changes of inputs/outputs and neglect the input/output slacks. On the other hand, ...

Preserving location privacy is increasingly an essential concern in Vehicular Adhoc Networks (VANETs). Vehicles broadcast beacon messages open form that contains information including vehicle identity, speed, location, and other headings. An adversary may track the various locations visited by a using sensitive transmitted beacons such as identity location. By matching used at locations, learns...

pavement permanent deformations due to lack of shear strength in mixture are a major reason of rutting. any simple test to determine mixtures resistance to permanent deformation isn’t distinguished in the 1st level of superpave mix design method and prevalent methods for evaluating mixture rut resistance are expensive and time-consuming. two aggregate types, gradations, asphalt cements and fill...
