INTRODUCTION The success of pharyngeal surgery in the treatment of obstructive sleep apnea syndrome depends on the appropriate selection of patients. OBJECTIVE To propose a new staging for indication of pharyngeal surgery in obstructive sleep apnea syndrome. METHODS A total of 54 patients undergoing extended tonsillectomy were retrospectively included, divided into six stages. Stage I: pati...

The Atom-bond-connectivity index ABC of a graph G is determined by d_i and d_j. In this paper, sharp results for the general which has chemical applications are found using different methods. These new inex investigated in terms its edges, vertices degrees. particular, some relations obtained involving topological indices; Randic index, Zagreb Harmonic Narumi-Katayama index. Indeed, improved he...

<abstract><p>We introduce the general Albertson irregularity index of a connected graph $ G and define it as A_{p}(G) = (\sum_{uv\in E(G)}|d(u)-d(v)|^p)^{\frac{1}{p}} $, where p is positive real number d(v) degree vertex v in $. The new not only generalization well-known \sigma $-index, but also Minkowski norm vertex. We present lower upper bounds on index. In addition, we study ext...

Consumers’ views of genetically modified foods (GM foods) can influence food producers’ decisions as to whether to market GM foods or whether to use conventional varieties. Through labelling, supported by certification, consumers could differentiate a GM food from a conventional food. A working group of the Codex Committee on Food Labelling identified seven approaches to labelling of GM foods. ...

This paper suggests a rethinking of the existing research about Genetically Modified (GM) food. Since the first batch of GM food was commercialised in the UK market, GM food rapidly received and lost media attention in the UK. Disagreement on GM food policy between the US and the EU has also drawn scholarly attention to this issue. Much research has been carried out intending to understand peop...

The evidence to date shows that these three types of maize production have co-existed without economic and commercial problems. This includes in regions such as Catalunya where GM (Bt) is concentrated. Where non GM maize has been required in some markets, supplies have been relatively easily obtained, based on market-driven adherence to on/post farm segregation and by the purchase of maize from...
