Through the AdS/CFT correspondence, Lifshitz spacetimes describe field theories with dynamical scaling (z 6= 1). Although curvature invariants are small, the Lifshitz metric exhibits a null singularity in the IR with a large tidal force that excites string oscillator modes. However, Lifshitz is not a vacuum solution of the Einstein equations – the metric is supported by nontrivial matter conten...

The inverse scale factor, which in classical cosmological models diverges at the singularity, is quantized in isotropic models of loop quantum cosmology by using techniques which have been developed in quantum geometry for a quantization of general relativity. This procedure results in a bounded operator which is diagonalizable simultaneously with the volume operator and whose eigenvalues are d...

considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. there are two direct and indirect methods tomeasure tensile strength. since direct methods always encompass difficulties in test setup, indire...

background: irritable bowel syndrome (ibs) with chronic abdominal pain and changes in bowel habits in the absence of any organic cause is identi_ed as the most common known gastrointestinal disorder. ibs affects both sexes and can occur at any age. diagnosis of this disease in younger patients and women is more likely. in the pathophysiology of ibs, hereditary, environmental, visceral, psycholo...

abstract in order to study the effects of quantitative and qualitative traits on cooking characteristics and protein percentage of 15 red bean genotypes, a randomized complete block design was conducted with three replications in normal irrigation and drought stress. these traits were measured in farm and nutrition laboratory employing international standard of ciat. analyses of variance showed...
