Isolation and partial purification of a hemolytic sphingomyelin-inhibitable fraction from the sea anemone Anthopleura nigrescens
(2014-03)
Actinoporins are highly hemolytic pore-forming proteins with a molecular mass of around 20 kDa and high affinity for sphingomyelin-containing membranes. On the crude extract of the sea anemone Anthopleura nigrescens, the ...
First measurements of methyl tert-butyl ether (MTBE) in the ambient air in San Jose, Costa Rica
(2014)
A great interest has arisen in establishing the impact of organic compounds on human health and air quality, especially those compounds emitted by automotive traffic. Knowledge of urban air pollutant concentrations is ...
A proposal for implementing PBL in programming courses
(XL Latin American Computing Conference, CLEI 2014, 2014)
In the search of teaching strategies more consistent with the current needs of the industry and with the new university pedagogical model, an action research project was carried in the programming courses of the study ...
Sizeable beta-strength in 31Ar (β3p) decay
(Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2014-10-07)
We present for the first time precise spectroscopic information on the recently discovered decay mode β-delayed 3p-emission. The detection of the 3p events gives an increased sensitivity to the high energy part of the ...
Multiparticle emission in the decay of Ar 31
(American Physical Society, 2014-06-25)
A multihit capacity setup was used to study the decay of the dripline nucleus 31Ar, produced at the ISOLDE facility at CERN. A spectroscopic analysis of the β-delayed three-proton decay of 31Ar is presented for the first ...
Strategy of bioremediation in recirculating aquaculture systems using constructed microbial mats
(Journal of Chemical, Biological and Physical Sciences, 2014-11-30)
Due to strict international standards, every day there is greater interest in developing environmentally sound treatment systems in aquaculture facilities that can remove contaminants from effluent and allows for the reuse ...
Evaluating SODA for Indo-Pacific Ocean decadal climate variability studies
(Journal of Geophysical Research: Oceans, 2014-10-31)
Estimates of changes in upper ocean temperature, heat content, and sea level are dependent on the coverage of subsurface observations in space and time. Historically, these data are sparse, which has limited our understanding ...
A combined experimental and theoretical study of gas sorption on nanoporous silver triazolato metal-organic frameworks
(2014-01-01)
A new silver-triazolate metal-organic framework (MOF), {Ag 3[Ag5(μ3-3,5-tBu 2tz)6](BF4)2}n (2), has been prepared and structurally characterized. The CO2 sorption properties of this new MOF and previously reported isostructural ...
The rock coast of South and Central America
(Geological Society Memoirs 2014, 2014-07)
The great variety of climatic conditions, tidal ranges and wave regimes of South and Central America act on a complex
geology and tectonic framework. Many of the rock and cliffed coasts of South America are strongly ...
New species of Potamocoris Hungerford (Heteroptera, Potamocoridae) from Costa Rica and a key to the species
(Magnolia Press, 2014-11)
A new potamocorid species, Potamocoris sitesi NEW SPECIES, with its two wing morphs (coleopteroid and macropterous) are described from Costa Rica. Descriptions are supported with photographs and illustrations. Parameres ...
