Most of the work on quantum logic (since the seminal paper [4]) has continued to adopt the lattice of closed subspaces of a Hilbert space as the basis for its semantics [11, 8]. Here we take a quite different approach, what we call the exogenous approach. The key idea is to keep the models of the classical logic (say propositional logic) as they are, to produce models for the envisaged quantum ...

introduction: pharmacists and pharmaceutical services are among the most important resources and programs in providing health for a society. pharmacists as the key players in presenting health services, greatly impact on the health of a society and if they suffer low job satisfaction, their dissatisfaction may relatively threaten health in a society. this study was conducted to determine irania...

objective: every cell type is characterized by a specific transcriptional profile together with a unique epigenetic landscape. reprogramming factors such as oct4, klf4, sox2 and c-myc enable somatic cells to change their transcriptional profile and convert them to pluripotent cells. small molecules such as bix-01294, bay k8644, rg-108 and valproic acid (vpa) are reported as effective molecules ...

Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...

  Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreas...
