Aim and Background: Safe airway maintenance in patients under general anesthesia is the most important duty of anaesthesiologists. Classic laryngeal mask airway (CLMA) is a supra-glottic device to achieve this aim. There are different insertion techniques for this device, but the best of them is unknown. Methods a...
The Narumi-Katayama index was the first topological index defined by the product of some graph theoretical quantities. Let $G$ be a simple graph with vertex set $V = {v_1,ldots, v_n }$ and $d(v)$ be the degree of vertex $v$ in the graph $G$. The Narumi-Katayama index is defined as $NK(G) = prod_{vin V}d(v)$. In this paper, the Narumi-Katayama index is generalized using a $n$-ve...
Let $G=(V,E)$ be a simple connectedgraph with $n$ vertices, $m$ edges and sequence of vertex degrees$d_1 ge d_2 ge cdots ge d_n>0$, $d_i=d(v_i)$, where $v_iin V$. With $isim j$ we denote adjacency ofvertices $v_i$ and $v_j$. The generalsum--connectivity index of graph is defined as $chi_{alpha}(G)=sum_{isim j}(d_i+d_j)^{alpha}$, where $alpha$ is an arbitrary real<b...
The development of genetically modified (GM) food has been a matter of considerable interest and worldwide public controversy. As a result ‘uncertainties’, ‘risks’ and ‘benefits’ that such new technologies portray to the food industry and consumers have been widely disseminated. However, there is limited understanding of what lies behind “demand side effects” to the introduction of these ‘poten...
This paper draws upon survey evidence from Spain to examine the causal relationship between attitudes towards science and attitudes towards Genetically Modified (GM) food. It employs structural equation modelling and explores this association by using sub-samples made of regional groups that have GM agriculture. Our results suggest specific behavioural mechanisms in explaining GM consumer attit...
