The gravity method is a nondestructive geophysical technique that measures differences in the earth’s gravitational field at specific locations. It has found numerous applications in engineering and environmental studies including locating voids and karst features, buried stream valleys, water table levels and the determination of soil layer thickness. The success of the gravity method depends ...

The relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. This approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. The technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. The ...

this study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by astm d- 6751. accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . alkaline catalysed transesterfication was carried out by  using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...

Data strongly suggestthat the longer patients have been treated in New Castle State Hospital, the higher the probability that they will demonstrate the low specific gravity syndrome. It is believed that a probably unrecognized alteration in human water metabolism among institutionalized patients who have chronic, severe epilepsy and who have been administered anticonvulsant drugs for many years...

Modifications of general relativity provide an alternative explanation to dark energy for the observed acceleration of the Universe. Modified gravity theories have richer observational consequences for large scale structures than conventional dark energy models, in that different observables are not described by a single growth factor even in the linear regime. We examine the relationships betw...

Membrane fragments from high potassium (HK) and low potassium (LK) sheep red cells were separated by density gradient centrifugation. Three preparations were studied: (1) HK membranes sonicated for 20 minutes, (2) HK membranes sonicated for 3 minutes, and (3) LK membranes sonicated for 3 minutes. The adenosine triphosphatase (ATPase) activity in the maximally disrupted preparation (1) was not s...
