The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...

Sera from free-ranging Atlantic bottlenose dolphins (Tursiops truncatus) in the Indian River Lagoon, Florida (IRL) (n = 122), and the estuarine waters near Charleston, South Carolina (CHS) (n = 82) were collected from 2003 to 2007 and analyzed for antibodies to several bacterial and viral pathogens. Serological evidence of exposure to Chlamydophila psittaci; Eastern, Western, and Venezuelan equ...

Building stones and clay-rich Nile mud were ancient Egypt’s main raw construction materials. While the mud was easily accessible along the Nile river valley, the immense quantities of the different stone materials used for construction of the famous pyramids, precious temples and tombs needed a systematic quarrying organization, well arranged transport logistics over extreme distances and a hig...

This article details a Bayesian analysis of the Nile river flow data, using a similar state space model as other articles in this volume. For this data set, Metropolis-Hastings and Gibbs sampling algorithms are implemented in the programming language Ox. These Markov chain Monte Carlo methods only provide output conditioned upon the full data set. For filtered output, conditioning only on past ...

The objective of this work was to evaluate a Bayesian model-based clustering method to identify the strains of Nile tilapia (Oreochromis niloticus) individuals from fish farms in Southern Brazil. Assignment methods using nine microsatellite loci were applied to differentiate individuals of five reference strains (GIFT, GST, Nilótica, Chitralada, and Saint Peter) and to identify individuals of u...

BACKGROUND Bovine trypanosomosis is a serious constraint to agricultural production in extensive areas of Ethiopia. METHODOLOGY A cross-sectional study was conducted to determine the prevalence of bovine infection with trypanosomes and to identify the prevailed trypanosome species in three districts of the East Gojjam zone bordering the Blue Nile River from March 2005 to February 2006. Cattle...

We consider the problem of testing for homogeneity of variance in a time series that has long memory structure. We demonstrate that a test whose null hypothesis is designed to be white noise can in fact be applied, on a scale by scale basis, to the discrete wavelet transform of long memory processes. In particular, we show that evaluating a normalized cumulative sum of squares test statistic us...

The Egyptian tortoise Testudo kleinmanni was recently split into two species on the basis of apparent differences in shell morphology and markings. Testudo kleinmanni was restricted to areas west of the Nile river and a new form, T. werneri, was described which occurred east of the Nile river (Perälä, 2001). However, when the morphometric analysis on which this decision was based (Perälä, 2001)...

The natural radionuclides Ra, Th and K contents in the Nile river sediments at various locations in Upper Egypt from Aswan to El-Minia have been investigated using gamma spectrometric analysis. Determination and measurement of radionuclide concentration are of great importance for assessment of external radiation dose received by man. The range and mean values of Ra, Th and K activity concentra...
