Tsunamis from Tectonic Sources along Caribbean Plate Boundaries
(2015)
The Caribbean region, home to more than 100 million people, has seen for the last 500 years at Least 75 documented tsunamis (von Hillebrandt-Andrade, 2013). It has been estimated that more than 4500 people have perished ...
Orientation effect in poly (butylene succinate) fibers
(Polymers & Polymer Composites vol.11 no.1 51-56 2003, 2003)
Fibers of poly (butylene succinate) (PBS) were prepared using a single screw extruder at various take-up speeds. Changes in fiber structure, morphology and physical properties were investigated using sonic velocity ...
Neighbourhood structure and light availability influence the variations in plant design of shrubs in two cloud forests of different successional status
(Annals of Botany, 2016-07)
Background and Aims Plant design refers to the construction of the plant body or its constituent parts in terms of form and function. Although neighbourhood structure is recognized as a factor that limits plant survival ...
Physical, mechanical and hydration kinetics of particleboards manufactured with woody biomass (Cupressus lusitanica, Gmelina arborea, Tectona grandis), agricultural resources, and Tetra Pak packages
(Waste Management and Research vol.32 no.2 106-114 2014, 2014-02-11)
Lignocellulosic wastes resulting from agricultural activities as well as Tetra Pak residues from urban centres can cause significant levels of pollution. A possible action to minimize this problem is to use them in the ...
Abelian covers of alternating groups
(Archiv der Mathematik 107 135-150, 2016-07-07)
Let G = A n , a finite alternating group. We study the commuting graph of G and establish, for all possible values of n barring 13, 14, 17, and 19 whether or not the independence number is equal to the clique-covering number.
Efficiency measurement and Monte Carlo simulations of a CeBr3 scintillator
(Applied Radiation and Isotopes Vol.120. 71-75 2016, 2016-11)
CeBr3 crystals meet many of the demands of high performance scintillators, due to their excellent timing properties, good effective Z and high photon yield. It is important to characterize their efficiency and to verify ...
Synthesis of Dihydroindolo[2,3-c]carbazole as Potential Telomerase Inhibitor
(Journal of Heterocyclic Chemistry vol.53 no.3 762-766 2015, 2015-05-27)
The dictyodendrins A-E were the first marine natural products that show inhibition of telomerase. A versatile and convergent route was described for the synthesis of derivatives of these pyrrolo[2,3-c]carbazole alkaloids ...
The manufacture and properties of oil palm and pineapple leaf fiberboard panels
(WIT Transactions on Ecology and the Environment, 2014)
Particleboards were manufactured from oil palm fruit, the oil palm mesocarp fiber of Elaeis guineensis, the leaves of pineapple (Ananas comosus) and the sawdust from three fast-growing species of trees (Gmelina arborea, ...
E-commerce and coffee in Costa Rica: Case studies of costa rican roaster companies
(Proceedings - 2015 41st Latin American Computing Conference [CLEI], 2015-12-17)
This paper presents the results of an exploratory multiple case study about the use of e-commerce for selling roasted coffee from Costa Rica. Four Costa Rican roasting companies are considered. This study is aimed at ...
Determinación del flujo de agua para la biorremediación en sistemas recirculados acuaculturales utilizando tapetes microbianos construidos
(2015)
The effect of water flow rate was evaluated on the microbial mats efficiency to remove total ammonia nitrogen (TAN, NH4+-N+ NH3-N), nitrite (N-NO2-), nitrate (N-NO3-) and orthophosphate (P-PO4-3) in a pilot recirculation ...
