Single spins in solid-state systems are often considered prime candidates for the storage of quantum information, and their interaction with the environment the main limiting factor for the realization of such schemes. The lifetime of an excited spin state is a sensitive measure of this interaction, but extending the spatial resolution of spin relaxation measurements to the atomic scale has bee...

The present study seeks to examine the factors affecting information search of heads of households in purchasing an outbound package tour. A sample of 60 academics and non-academics in the field of tourism was chosen. Sampling methods were judgmental and snowball sampling. In order to gather data, we used a semi-structured interview.  Thematic analysis was applied for data analysis, and the col...

Using an extended Lee-Yang theorem and GKS correlation inequalities, we prove, for a class of ferromagnetic multi-spin interactions, that they will have a phase transition (and spontaneous magnetization) if, and only if, the external field h = 0 (and the temperature is low enough). We also show the absence of phase transitions for some nonferromagnetic interactions. The FKG inequalities are sho...

BACKGROUND: Sustainable agriculture today plays an important role in the utilization of organic matter and biofertilizers to eliminate or reducing chemical fertilizer, promoting fertility and preserving biological activities, enhancing the health of agricultural products and reducing environmental damage. OBJECTIVES: Current research was conducted to asse...
