Two experiments were established in 2003 at the Rice Research and Extension Center near Stuttgart, Ark., to evaluate the potential of penoxsulam (Grasp) as part of a rice weed control program. In experiment one, penoxsulam applied alone and in tank mixtures early postemergence (EPOST) (two-leaf rice, one-leaf grass, two-leaf weeds) was evaluated, and experiment two evaluated penoxsulam applied ...

Malate oxidation supported C(2)H(2) reduction by bacteroids isolated from Sesbania rostrata stem nodules. Optimal activity reached 7.5 nanomoles per minute per milligram of dry weight and was in the same order of magnitude as that observed with succinate but always required a lower O(2) tension. Malate dehydrogenase (EC 1.1.1.37), purified 66-fold from bacteroids, actively oxidized malate (K(m)...

Background. Sesbania grandiflora has been traditionally used as antidiabetic, antioxidant, antipyretic, and expectorant and in the management of various ailments. Materials and Methods. The study evaluates the antidiabetic activity of methanolic extract of Sesbania grandiflora (MESG) in type 2 diabetic rats induced by low dose streptozotocine and high fat diet. Diabetic rats were given vehicle,...

The tropical legume Sesbania rostrata can be nodulated by Azorhizobium caulinodans on both its stem and its root system. Here we investigate in detail the process of root nodulation and show that nodules develop exclusively at the base of secondary roots. Intercellular infection leads to the formation of infection pockets, which then give rise to infection threads. Concomitantly with infection,...

In a recent paper, Valdès-Parada and Alvarez-Ramirez [Phys. Rev. E 84, 031201 (2011)] used the technique of volume averaging to derive a "frequency-dependent" dispersion tensor, D(γ)(*), the goal of which is to describe solute transport in porous media undergoing periodic processes. We describe two issues related to this dispersion tensor. First, we demonstrate that the definition of D(γ)(*) is...

This Essay reexamines Thomas Hobbes's understanding of international order. Hobbes defended the establishment of an all-powerful sovereign as the solution to interpersonal conflict, and he advanced an analogy between persons and states. Extending this "domestic analogy," theorists following Hobbes have supposed that a global sovereign would prove the solution to interstate conflict. Yet Hobbes ...

An experiment was carried out in a roadside agroforestry system established along farm roadsides of Bangladesh Agricultural University, Mymensingh, to investigate the effects of pruning and pollarding on shoot development in Sesbania grandiflora L. Six treatment combinations with the stock plants studied during the period from August to September, 2007. The results revealed that the different p...
