purpose headache at altitudes has had an incidence of 25-62% through many related studies. many reasons are identified concerning headache at altitudes such as acute mountain sickness (ams), sinus headache, migraine, tension type headache, and frontal tension headache. this study tried to compare different types of headache among trekkers on mount damavand, a 5671m mountain, iran, to find their...

in 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for xenia or metaxenia in persian walnut. pistillate flowers of ‘jamal’, ‘chandler’, ‘hartley’ and ‘pedro’ were crossed with the pollen of ‘serr’, ‘z60’ and ‘damavand’. the pistillate flowers on each female parent were covered about one week ...

yarrow (achillea spp.) belonging to the family of asteraceae with useful properties, such as anti-diaphoretic, anti-hemorrhagic, anti-inflammation, anti-biotic, anti-fungal, anti-bacterial, carminative and anti-oxidant effects. the present investigation assessed the morphological diversity of achillea aucheri, which is indigenous plant from damavand mountain of iran. the samples were collected ...

The European Parliament has continuously supported these goals. It is a common understanding that this change will require a transition from monopolised hierarchically controlled Power networks to customer oriented Smart Grids operating in deregulated energy markets. However, this poses several regulatory, organizational and technical challenges to be identified and addressed. To that end sever...

It is shown that the quantization of a superparticle propagating in an N = 1, D = 4 superspace extended with tensorial coordinates results in an infinite tower of massless spin states satisfying the Vasiliev unfolded equations for higher spin fields in flat and AdS4 N = 1 superspace. The tensorial extension of the AdS4 superspace is proved to be a supergroup manifold OSp (1|4). The model is man...

The delivery of Public Services to citizens is becoming a challenging task, as urban populations increase and the related networks are becoming more complex and entangled. In this article, we present a platform designed for the optimal coordination of a city's public agencies and emergency response teams. Such coordination is particularly relevant in emergency situations when the infrastructure...

This article proposes a new business model framework that allows the design and analysis of value networks for mobile services in a public context. It starts from a validated business model framework that relies on 12 design parameters to evaluate business models on, and expands it by eight parameters to include important aspects that come into play when a public entity (i.e. a city government)...

Electrical utilities around the world are working toward the implementation of demand response programs, which are focused on either reducing electricity usage or shifting its use at times of high wholesale marketing prices. These programs try to involve the consumer participation in the operations of the electric grid. One of the goals of the Smart Grid concept is to develop grid modernization...
