This article analyses the push and pull factors that bring visitors to the Iranian national parks. The study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. Survey conducted in Boujagh National Park, an area of 3177 hectares located in the north of the Iran, produced 400 questionnaires. The factor analysis identified four push ...

This paper describes a technique called producer-push that enhances the performance of a page-based software distributed shared memory system. Shared data, in software DSM systems, must normally be requested from the node that produced the latest value. Producer-push utilizes the execution history to predict this communication so that the data is pushed to the consumer before it is requested. I...

New technologies enable educators to modify their teaching methods and extend their reach beyond the classroom. One of these methods that can be applied to communicate with students is through the use of push notifications on smartphones. Instead of relying on students to use a spaced learning approach, which is proven to be more efficient than trying to study something in a short period of tim...

We show that the giant flares of soft gamma-ray repeaters ( ergs) can push the inner regions of a fall44 E ∼ 10 back disk out to larger radii by radiation pressure, while matter remains bound to the system for plausible parameters. The subsequent relaxation of this pushed-back matter can account for the observed enhanced X-ray emission after the August 27 giant flare of SGR 1900 14. Based on th...

The SecA ATPase associates with the SecY complex to push preproteins across the bacterial membrane. Because a single SecY is sufficient to create the conducting channel, the function of SecY oligomerization remains unclear. Here, we have analyzed the translocation reaction using nanodiscs. We show that one SecY copy is sufficient to bind SecA and the preprotein, but only the SecY dimer together...

BACKGROUND Tai chi is a form of exercise derived from the martial art folk traditions of China. The force used in tai chi includes different principles of mechanical advantage. No studies on the kinematic features of tai chi exercise have been published. OBJECTIVE To analyse the kinematics and electromyographic characteristics of tai chi. METHODS An experienced tai chi master was asked to p...

We develop a simple and generic method to analyze randomized rumor spreading processes in fully connected networks. In contrast to all previous works, which heavily exploit the precise definition of the process under investigation, we only need to understand the probability and the covariance of the events that uninformed nodes become informed. This universality allows us to easily analyze the ...
