Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one of the greatest disturbances to coral reef ecosystems in the Indo-Pacific, affecting not only coral reefs but also the coastal communities which rely on their resources. While injection approaches are increasingly used in an attempt to control COTS densities, most of them display severe drawbacks incl...

15. Supplementary Notes Research performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Develop Guidelines and Procedures for Stabilization of Sulfate Soils 16. Abstract Sulfate-bearing subgrade soils treated with calcium-based stabilizers often experience heaving problems (three-dimensional swell) due to chemical reactions w...

Mobile ad hoc networks (MANETs) define a challenging computing scenario where access to resources is restrained by connectivity among hosts. Replication offers an opportunity to increase data availability beyond the span of transient connections. Unfortunately, standard replication techniques for wired environments mostly target improvements to fault-tolerance and access time, and in general ar...

The grading entropy concept can be adapted to the field of geotechnics, to establish criteria for phenomena such as particle packing, particle migration and filtering, through a quantified expression of the order/disorder in the grain size distribution, in terms of two entropy-based parameters. In this paper, the grading entropy theory is applied in some geotechnical case studies, which serve a...

Cable and Wireless, Jamaica (C&WJ) operated in Jamaica under an exclusive license which made them a virtual monopoly. In 1999 the Government of Jamaica decided to renegotiate the license and liberalize the telecommunications industry. Early in the liberalization process new companies entered the market and C&WJ struggled to cope with the new competitive dynamics of the market. C&WJ although dom...

Abstract For conservation interventions of historic masonry generally lime-based mortars such as pure air lime mortars, lime-pozzolan natural hydraulic and ternary (lime-pozzolan-cement) are used. The main reason is that their hygric mechanical (strength ductility) performance easy to adapt most existing (compatibility requirements). Although the basic appropriateness for restoration undisputed...

The use of lime as a binder in masonry lining mortars plays an important role its conservation and durability. Knowledge the mechanical characteristics pre-existing restoration is essential order to guarantee compatibility between them for avoiding appearance pathologies. paper mainly focuses on study performance lime-based be applied rehabilitation works old buildings. Four types were tested w...

Acidity is released in high amounts when pyrite-bearing sediments in the coastal plains of Malaysia are drained for development, either agriculture or otherwise. The soils formed from these materials are called acid sulphate soils, which are characterized by low pH and high exchangeable Al that adversely affect plant growth. A study was conducted with the objective of increasing rice yields on ...
