Abstract[1] Natural resources as a source of wealth can increase prosperity or impede economic growth.  Empirical studies with different specifications and data are also mixed on whether natural resources are curse or blessing. In fact, the variety of model specifications, measurements, and samples in the empirical literature makes it difficult to generalize the results. In this study, a growth...

background: a large proportion of patients presenting with lumbar disc disease are opium addicts in our region. it was, therefore, hypothesized that morphine might affect the intervertebral disc. we investigated the histological findings of morphine dependency on intervertebral discs in rat.   methods: forty nmri adult male rats (230-250 g) placed on ordinary diet and received aqueous solution ...

Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...

purpose: the goal of this study was to compare differences in the mean heterophoria and fusional amplitudes before and after photorefractive keratectomy (prk) for myopia. methods: in a prospective controlled study, myopic patients were treated with aspheric and wavefront-guided (personalized) prk. the manifest refraction, visual acuity, fusional amplitudes and heterophoria were evaluated preope...

Background: Smoking is one of the most common causes of mortality in the world. Emotional intelligence is the adapting ability to respond to the environment and people appropriately. It plays an important role in various aspects of life such as facing stressful situations and consequently, smoking. This study aimed to investigate the relationship between nicotine dependency and emotional intell...

It was recently shown that wavepackets with skewed momentum distribution exhibit a boomerang-like dynamics in the Anderson model due to localization: after an initial ballistic motion, they make U-turn and eventually come back their starting point. In this paper, we study robustness of quantum boomerang effect various kinds disordered dynamical systems: tight-binding models pseudo-random potent...
