Between 2001 and 2003 the London Health Commission undertook health impact assessments (HIAs) on a series of strategies developed by the Greater London Authority and the Mayor of London. The HIAs were rapid, each involving a literature review and a participant workshop. In all cases the reports made a series of recommendations that were given to the Mayor. The HIAs led to changes and ensured th...

Trait-based approaches provide a mechanistic framework to understand and predict the structure and functioning of microbial communities. Resource utilization traits and trade-offs are among key microbial traits that describe population dynamics and competition among microbes. Several important trade-offs have been identified for prokaryotic and eukaryotic microbial taxa that define contrasting ...

This paper presents a critical analysis of health impact assessment (HIA) in the Republic of Ireland (ROI) in the context of institutional policy and practice. It begins with a brief background to the origins and aims of HIA. Core developments in health and environmental sectors pertaining to HIA in the ROI are then considered. A series of significant developments have taken place in these sect...

a graph is textit{symmetric}, if its automorphism group is transitive on the set of its arcs. in this paper, we  classifyall the connected cubic symmetric  graphs of order $36p$  and $36p^{2}$, for each prime $p$, of which the proof depends on the classification of finite simple groups.

we give a survey of recent applications of group rings to combinatorics and tocryptography, including their use in the di erential cryptanalysis of block ciphers.

a kernel $j$ of a digraph $d$ is an independent set of vertices of $d$ such that for every vertex $w,in,v(d),setminus,j$ there exists an arc from $w$ to a vertex in $j.$in this paper, among other results, a characterization of $2$-regular circulant digraph having a kernel is obtained. this characterization is a partial solution to the following problem: characterize circulant digraphs which hav...

Introduction: Physical wedge as a useful tool has been utilized in radiotherapy to modify photon beam shape and intensity such that it distributes dose uniformly in tumor site and reduces hot points. Since during Linac commissioning dosimetric parameters like output factors and lateral dose profiles are measured only for symmetric open and wedged fields, so calculation the par...

Diffusion tensor imaging provides structural information in medical images in the form of a symmetric positive matrix that provides, at each point, the covariance of water diffusion in the tissue. We here describe a new approach designed for smoothing this tensor by directly acting on the field of frames provided by the eigenvectors of this matrix. Using a representation of fields of frames as ...

Let $Rin textbf{C}^{mtimes m}$ and $Sin textbf{C}^{ntimes n}$ be nontrivial involution matrices; i.e., $R=R^{-1}neq pm~I$ and $S=S^{-1}neq pm~I$. An $mtimes n$ complex matrix $A$ is said to be an $(R, S)$-symmetric ($(R, S)$-skew symmetric) matrix if $RAS =A$ ($ RAS =-A$). The $(R, S)$-symmetric and $(R, S)$-skew symmetric matrices have a number of special properties and widely used in eng...

Process-induced strain dependence of impact ionization efficiency (IIE) in nMOSFETs with a tensile contact etch stop layer (CESL) is presented for the first time. From the universal relationship between the IIE and the electric field in the pinch-off region, a difference in the IIE of nMOSFETs between without and with the tensile CESL is found. This result can be mainly attributed to the narrow...
