OBJECTIVE To test the reliability and validity of the Asthma Trigger Inventory (ATI) applied to a pediatric population. METHOD Children with asthma (N = 272, 56% male, age 7-17) and their primary caregivers answered together an asthma trigger inventory, ATI (Ritz, Steptoe, Bobb, Harris, & Edwards, 2006) developed for adults. Cronbach's alpha, principal component analysis (PCA), hierarchical r...

In the recent years, WiFi standard has been used to develop different kind of wireless networks due to its flexibility and the availability of cheap off the shelf hardware. Even if the standard itself lacks mobility support, it has been used in networks with mobile nodes. When mobility is involved, a fast handoff is of paramount importance, especially with multimedia applications. The current I...

Dynamics of electrical activity in the neo- and archipaleocortex in response to directing and triggering conditioned signals during delayed responses was studied in cats with chronically implanted electrodes. Dynamics of unit activity of some mesencephalic structures was also studied in rats in response to sensory stimuli and during the sleep-wakefulness cycle. Neurophysiological analysis revea...

Electrocardiogram (ECG) is required during magnetic resonance (MR) examination for monitoring patients under anaesthesia or with heart diseases and for synchronizing image acquisition with heart activity (triggering). Accurate and fast QRS detection is therefore desirable, but this task is complicated by artefacts related to the complex MR environment (high magnetic field, radio-frequency pulse...

let $pounds$ be the category of locally compact abelian groups and $a,cin pounds$. in this paper, we define component extensions of $a$ by $c$ and show that the set of all component extensions of $a$ by $c$ forms a subgroup of $ext(c,a)$ whenever $a$ is a connected group. we establish conditions under which the component extensions split and determine lca groups which are component projective. ...

The main allergen responsible for contact dermatitis to nail polish is tosylamide-formaldehyde resin. The so-called hypoallergenic nail polishes are suposedly free of agents that commonly trigger reactions. The commercially available products and their compositions were studied. It was observed that most brands present at least one component capable of triggering the disease; therefore, allergi...
