    Abstract: We have study here the topological properties as w ell as the elastic and thermodynamical properties of DNA molecules from an analysis of an antiferromagnetic spin chain system. The topological property such as the linking number can be derived from the Chem-Simons topology associated with a quantum spin and two indistinguishable fermions are made ... Show More

    Abstract: Barley (Hordeum vulgare L.) is one of the most important staple food crops in the highlands of Ethiopia. However, the production and productivity of barley are constrained by various a biotic and biotic stresses. Among the biotic stresses, barley net blotch and leaf rust are the most destructive diseases of barley. The field experiment was conducte... Show More

    Abstract: The background of this contribution is the ongoing extended debate over quantum effects in the biology since decades. Typical examples of the quantum biology are photosynthesis, enzymatic activities, bird navigation and especially the coherent movement of microtubules. The reason for all these effects is dominantly the quantum coherence of waves. T... Show More

    Abstract: The Genes such as carbonic anhydrase IX (CAIX), hypoxia inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) have been suggested as hypoxic biomarkers in cancer. Indeed, these endogenous biomarkers have been shown to have stronger prognostic value response after treatment by irradiation. However, inconsistent results suggest tha... Show More
