Four phenotypically similar bacterial strains isolated from fungal, plant, and human sources were identified as Azospirillum species. Strains RC1 and LOD4 were isolated from the mycelium of the apple root pathogen Rhizoctonia solani AG 5 and from the rhizosphere of wheat grown in apple orchard soil, respectively. Strains C610 and F4626 isolated from human wounds were previously misclassified as...

Common integrated assessment models produce the counterintuitive result that higher risk aversion does not lead to stronger near-term abatement. This paper re-examines this result with a DICE model that is fully coupled with a thermohaline circulation model. It also features Epstein-Zin utility and uncertainty about climate sensitivity that resolves after some time. The simulations show that av...

Article history: Received 21 April 2008 Received in revised form 13 May 2009 Accepted 14 May 2009 Available online 27 May 2009 This paper assumes that the decision makers of OPEC (or at least of its core members) are interested in both profits and political payoffs (support, popularity, being a hero of the Arab or Islamic street, etc.). The oil weapon, i.e. a reduction of output is the most pow...

abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...

Several studies suggest the involvement of Na+ and HCO3- transport in the formation of cerebrospinal fluid. Two Na+-dependent HCO3- transporters were recently localized to the epithelial cells of the rat choroid plexus (NBCn1 and NCBE), and the mRNA for a third protein was also detected (NBCe2) (Praetorius J, Nejsum LN, and Nielsen S. Am J Physiol Cell Physiol 286: C601-C610, 2004). Our goal wa...

Aim/purpose – In this paper, a market volatility-robust portfolio composition frame- work under the modified Markowitz’s approach with use of sampling methods is developed in order to improve allocation efficiency for financial in- struments formulation procedure at an increased volatility. Design/methodology/approach overcome risk not receiving optimal solution optimization (suboptimal outcome...

Many obscure points remain to be resolved with respect to the transport of photosynthates from source to sink through sieve tubes. It is very important to be able to collect and analyze the phloem sap if an attempt is to be made to explain the phloem transport system. The insect laser technique (Kawabe et al. 1980) has been shown to be useful method for the study of this problem. The insect las...
