the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولLarger benthic foraminifera from the Middle Eocene
Larger benthic foraminifera (LBF) are common and diverse throughout the Paleogene sediments of southern Tanzania, but have previously been little studied. A recent programme of onshore drilling known as the Tanzania Drilling Project has recovered large proportion of this succession for palaeoclimatic and palaeontological study. The sediment is largely a hemipelagic clay with secondary gravity s...
متن کاملBa incorporation in benthic foraminifera
Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba /Ca can be used to reconstruct the latter. Alternatively, Ba /Ca from foraminiferal shells can also be used to reconstruct salinity in coastal settings in which seawater Ba con...
متن کاملTesting the utility of paleonutrient proxies Cd/Ca and Zn/Ca in benthic foraminifera from thermocline waters
[1] Reconstruction of oceanic nutrient concentrations in the past provides information about nutrient cycling and physical circulation and the role these processes have played in past climate changes. The Cd/Ca and Zn/Ca of benthic foraminifera have been used successfully to reconstruct past deep ocean nutrient concentrations. In this study we test the ability of benthic foraminiferal Cd/Ca and...
متن کاملC, and oxidation of organic carbon and methane in sediment porewater: Implications for paleo-proxies in benthic foraminifera
I present a numerical diffusion–advection-reaction model to simulate CO2 chemistry, d C, and oxidation of organic carbon and methane in sediment porewater. The model takes into account detailed reaction kinetics of dissolved CO2 compounds, H2O, H , OH , boron and sulfide compounds. These reactions are usually assumed to be in local equilibrium, which is shown to be a good approximation in most ...
