This article argues that investigating the conceptual structure underlying the use of the pluperfect and the future perfect reveals a new complex type of nested dual mental time travel: mental time travel into posteriority embedded into mental time travel into “anteriority in the past” (underlying the pluperfect) versus mental time travel into posteriority embedded into mental time travel into ...
The collapse of geographical space over the last 200 years has had profound effects on the circulation of human populations and on the transfer of infectious diseases. Three examples are used to illustrate the process: (a) the impact of the switch from sail to steamships in importing measles into Fiji over a 40-year period; (b) changes in measles epidemic behaviour in Iceland over a 150-year pe...
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
The application domain of intelligent transportation is plagued by a shortage of data sources that adequately assess traffic situations. Currently, to provide routing and navigation solutions an unreliable travel time database that consists of static weights as derived from road categories and speed limits is used for road networks. With the advent of Floating Car Data (FCD) and specifically th...
At its core, genetics is a historical discipline. Mutations are passed on from generation to generation and accumulate as a result of chance as well as of selection within and between populations and species. However, until recently, geneticists were confined to the study of present-day genetic variation and could only indirectly make inferences about the historical processes that resulted in t...
This paper applies nonparametric and semiparametric methods to investigate the distribution of the value of travel time (VOT) from experimental binary choice data using minimal prior distributional assumptions. Using a large dataset, results indicate that the VOT is approximately distributed as lognormal within the range for which observations exist. This implies that the lognormal would be sui...
T IME travel, I maintain, is possible. The paradoxes of time travel are oddities, not impossibilities. They prove only this much, which few would have doubted: that a possible world where time travel took place would be a most strange world, different in fundamental ways from the world we think is ours. I shall be concerned here with the sort of time travel that is recounted in science fiction....
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
