the rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. however, plants in general may have a different ability to sustain soil. the objective was to determine the effects of reclamation practices including haloxylon ammodendron and atriplex canescens plantation o...

the decisions made in the planning phase of a building project greatly affect its future operation and maintenance (o&m;) cost. recognizing the o&m; cost of condominiums’ common facilities as a critical issue for home owners, this research aims to develop an artificial neural network (ann) o&m; cost prediction model to assist developers and architects in effectively assessing the impacts of the...

This paper documents my research at GSIA, Carnegie Mellon University, during the summer of 1998. Topics on various aspects of the lift-and-project procedure are presented here. The overall theme binding all the results together here is the cut LP itself. One of the more promising results is an observation that the optimal solution to the cut LP will always contain a partition of all constraints...

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation be...

Electroless composite coatings used for achieving of high hardness, lubrication properties, non-stick surface, abrasive coating applications that by impregnation of soft and hard particles into Ni matrix. Electroless Nickel-phosphorous coatings properties and performance is greatly affected by the amount of phosphorus in them. The phosphor in this coating usually varies from 1 to 13 percent. In...

This work is undertaken to develop a methodology to enhance the management of dredged marine an the North of France. The main objective of this study is to determine the main characteristics of these sediments. In this order, physical, mineralogical and chemical properties of both types of sediments are measured. Moreover, their potential impacts on the environment are assessed throughout leach...

The authors present an epizootiological analysis of myxomatosis in Poland. The biological, physical and chemical properties of virus strains used for the production and control of 'Myxovac M' vaccine are discussed. The long-term stability, safety and efficacy of the vaccine are demonstrated. Laboratory experiments were confirmed in large-scale field observations.
