This study assessed concentrations in and intake of toxic and essential elements from formulas and foods intended for infants during their first 6months of life. Concentrations of the essential elements Ca, Fe, Zn, Mn and Mo were significantly higher in most formulas than in breast milk. Daily intake of Mn from formula varies from ten up to several hundred times the intake of the breast fed inf...

We describe a framework for relating available data on hazards to impact on infrastructure. It is designed to be used by simulation platforms that may focus on a single infrastructure layer or aim to study interactions between interdependent layers. The Hazard Impact Framework (HIF) provides a flexible scheme for capturing and maintaining data on the response of elements of critical infrastruct...

A novel coax-fed wideband loop antenna loaded with rectangular patches and U-shaped elements is presented and studied. By inserting a pair of rectangular patches inside the strip loops and employing a pair of U-shaped elements as the parasitic resonators, two additional resonances are excited and a good performance of bandwidth enhancement can be obtained. The measured results indicate that the...

The aim of this study was to do a preliminary assessment of the chemical and microbial surface water quality of the Chunies River. For this purpose sampling was undertaken on 25 and 26 May 2002, and a range of chemical (macro-elements, micro-elements and heavy metals) and microbial variables (HPC, total coliforms and faecal coliforms) were measured. The chemical water quality of the second sect...

In this paper, we introduce a four-port self-isolated UWB MIMO antenna for diversity applications. First, have developed basic radiating element of the proposed in four stages design, where patches geometrically different shapes were added at each stage to arrive final radiator form. The was designed on an FR-4 substrate with compact size 28 × 1.6 mm3. A tapered microstrip feeding employed enha...

We develop an adaptive output-feedback controller for a wave PDE in one dimension with actuation on one boundary and with an unknown anti-damping term on the opposite boundary. This model is representative of a torsional stick–slip instability in drillstrings in deep oil drilling, as well as of various acoustic instabilities. The key feature of the proposed controller is that it requires only t...

Breast-fed infants in Bangladeshi villages were weighed at 1, 2, 6, 9 and 12 months. The concentrations of zinc and copper in the breast milk were measured and the daily intake of these elements calculated. Breast milk Zn concentration decreased over the year but was comparable with that found in developed countries. The calculated daily intake decreased from 17.7 to 8.0 mumol (10-30% of recomm...

A compact UWB with WLAN notch-based four-element CPW fed MIMO/diversity antenna is presented in this paper. Multiple elements facilitate the design to transmit and receive signal from all directions enhancing channel capacity diversity performance. The inverted L-shaped stub attached ground enhances impedance bandwidth (10 dB) provides response. Plus cross-shaped decoupling structure accomplish...
