the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

The presence of abundant age-diagnostic dinoflagellate cysts in Ocean Drilling Program (ODP) Hole 913B (Leg 151), Deep Sea Drilling Project Hole 338 (Leg 38) and ODP Hole 643A (Leg 104) has enabled the development of a new biostratigraphy for the Eocene^Oligocene interval in the Norwegian^Greenland Sea. This development is important because the calcareous microfossils usually used for biostrati...

One of the aims of micropaleontological studies is to unravel the geological history of the surface of the earth in a manner that can be achieved as reliably, in relatively quick time and at the same time be economically be reasonable. Oil companies, who invest hugely in this high risk business of oil exploration, have undoubtedly gained much from micropaleontological studies. This is because o...

The Global Stratotype Section and Point for the newly defined Ediacaran System has been ratified at the base of the cap carbonate in Enorama Creek. A near-continuous section from the Marinoan glaciation to the base of the Cambrian is exposed in the Flinders Ranges, with type sections of included stratigraphic units exposed in the area around Brachina and Bunyeroo gorges. The stratigraphy and lo...

Abstract—Keyword Search is known as a user-friendly alternative for structured languages to retrieve information from graph-structured data. Efficient retrieving of relevant answers to a keyword query and effective ranking of these answers according to their relevance are two main challenges in the keyword search over graph-structured data. In this paper, a novel scoring function is proposed, w...

Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
