Exposure to mercury contaminated fish predisposes populations particularly children and pregnant women to various health hazards including neurotoxicity, reproductive abnormalities and cognitive disorders. Earlier studies in the Lake Albert community have demonstrated the presence of mercury in Nile tilapia and Nile perch. However, the risk estimates for vulnerable groups such as Children and p...

We present preliminary results from the FOCUS experiment (E831 at Fermilab) on the spectroscopy of bound states of a charm quark and a light quark with orbital angular momentum L = 1, called D∗ 2(cū, cd̄). A theoretical framework for the spectrum of heavy-light mesons is given by Heavy Quark Symmetry (HQS), which predicts both narrow and broad states. While the narrow states are well established...

Through the 1970’s to the present time the governance of the Japanese firm overseas has changed, moving towards a more international form of operation rather than operating as a peripheral organization based solidly on the Japanese headquarters office. Notwithstanding the evolution of their formal and informal management structures this research questions in detail the nature of computer softwa...

Marathon runners spend considerable time in outdoor training for and participating in marathons. Outdoor runners may experience high solar ultraviolet radiation (UVR) exposure. South Africa, where running is popular, experiences high ambient solar UVR levels that may be associated with adverse health effects. This feasibility study explores the use of personal dosimeters to determine solar UVR ...

One of the major hurdles in implementing chaotic communication schemes is the synchronization of chaotic systems. For the last two decades, numerous contributions of varying successes have been made by researchers from different disciplines for the synchronization of chaotic systems. Symbolic dynamics based synchronization method is shown to be capable of providing high quality synchronization ...

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were measured in sediments (surface and deeper sediments) and porewater of the lower Passaic River and Newark Bay (New Jersey, USA) to apportion their sources and conduct an ecological risk assessment. Positive matrix factorization was applied to identify sources of PCDD/Fs. Five source profiles were extracted from the positive matri...

Carnation (Dianthus caryophyllus L.) is valuable in terms of production and exports in the world. Increased vase life of cut flowers is an important factor for their market acceptability. For this purpose this study was carried out to examine the effect of plant essential oils as compared to 8-hydroxy-quinoline sulfate on the control of bacteria population and the longevity of carnation cut flo...

We present the results of a search for emissionline galaxies (ELGs) towards nearby voids, based on a sample selected on the HQS (Hamburg Quasar Survey)(Hagen et al. 1995) III-aJ objective-prism plates. The survey was based on the presence of emission-lines and therefore has the advantage to detect very faint objects (with all the flux in the emission-lines and almost no continuum), that would b...

We announce the discovery of a new gravitationally lensed QSO within the Hamburg Quasar Survey (HQS). HS 0818+1227 is at redshift z = 3.115 ± 0.001 and consists of two components separated by 2. ′′1 with R-magnitudes of 18.6 and 19.8 respectively. The two components have identical redshifts (4v ≤ 220 km/s) and identical emission line spectra with a flux ratio fA/fB = 8. In particular, both have...

A food scandal occurred in Taiwan in 2011 because the DEHP (di-2-ethylhexyl phthalate) had been intentionally used in food products. We assessed the daily intakes (DIs) and cumulative risk of phthalates in Taiwan's general population after the scandal. The DIs of 6 phthalates, including di-n-butyl phthalate (DnBP), di-iso-butyl phthalate (DiBP), and DEHP, were evaluated using urinary phthalate ...
