Weight-Length relationship and relative condition of the holothurian Isostichopus fuscus at Espíritu Santo Island, Gulf of California, México
(Revista de Biologia Tropical, 2008)
Holothurians were heavily exploited worldwide during the last decade. The high prices of the product prompted the opening of new fishing grounds in the west coast of American countries, such as Mexico and Ecuador. In these ...
Effect of sample conditioning on the water absorption of concrete
(ELSEVIER SCI LTD, 2011)
ASTM C1585 is commonly used to determine the absorption and rate of absorption of water in unsaturated hydraulic cement concretes. Unfortunately, a wide range of relative humidities can exist in the samples after this ...
Historical Sociology, International Relations Theory and the Imperial Condition
A historical-sociological approach to international relations highlights, in particular, the fundamental importance of the structures and practices of imperial and postcolonial field dynamics in the way international ...
CCTs and conditionalities: An exploratory analysis of not meeting conditional cash transfer conditionalities in Chile’s Families Programme
(2019)
Since the mid-1990s, conditional cash transfer programmes have rapidly proliferated in Latin America, although little research has examined the characteristics of families who do not meet programme conditionalities. In ...
On some conditionally solvable quantum-mechanical problems
(IOP Publishing, 2020-09-03)
We analyze two conditionally solvable quantum-mechanical models: a one-dimensional sextic oscillator and a perturbed Coulomb problem. Both lead to a three-term recurrence relation for the expansion coefficients. We show ...
The role of safety signals in fear extinction: An analogue study
Background and objectives
Safety signals are conditioned inhibitory stimuli that indicate the absence of unconditioned stimuli. It is not clear whether the presence of safety signals is detrimental or beneficial in ...

On the consistency conditions to braneworlds in scalar-tensor gravity for arbitrary dimensions
(2009-12-01)
We derive an one-parameter family of consistency conditions to braneworlds in the Brans-Dicke gravity. The General Relativity case is recovered by taking a correct limit of the Brans-Dicke parameter. We show that it is ...
