The biological control agent Pseudomonas fluorescens was used against the bacterial wilt causing Ralstonia solanacearum. The present investigation focuses on the role of defense related enzymes in imparting resistance in tomato against R. solanacearum. A total of ten rhizobacterial isolates were screened against R. solanacearum, of which three isolates (Pf3, Pf5 & Pf8) showed a maximum inhibiti...

The organometallic alkane complexes Re(Cp)(CO)(PF(3))(alkane) and Re(Cp)(CO)(2)(alkane) have been detected after the photolysis of Re(Cp)(CO)(2)(PF(3)) in alkane solvent. NMR and time-resolved IR experiments reveal that the species produced by the interaction of n-pentane with [Re(Cp)(CO)(PF(3))] are an equilibrium mixture of Re(Cp)(CO)(PF(3))(pentane) and Re(Cp)(CO)(PF(3))(pentyl)H. The intera...

Three distinct fractions containing polar glycolipids (PF1–3) were isolated from the chloroform soluble fraction of crude methanolic extract of red alga Chondria armata (Kütz.) Okamura on gel chromatography over Sephadex LH20. Their structure was elucidated by multidimensional nuclear magnetic resonance (NMR) techniques like 1H, 1H correlation spectroscopy (COSY), 1H, 1H total COSY (TOCSY), 1H,...

Many colorectal liver metastases are hypovascular, and their low level of perfusion is associated with limited drug uptake and poor response rates with regional chemotherapy. We have previously shown that hepatic arterial vasoconstrictors may increase drug delivery to liver tumours, but the underlying haemodynamic changes have not been defined. Using intraoperative laser Doppler flowmetry (LDF)...

Focused electron beam induced deposition (FEBID) is a single-step, direct-write nanofabrication technique capable of writing three-dimensional metal-containing nanoscale structures on surfaces using electron-induced reactions of organometallic precursors. Currently FEBID is, however, limited in resolution due to deposition outside the area of the primary electron beam and in metal purity due to...

conceptual knowledge here seems to be less fragmentary and more theoretical than with the general schemas. 9 (This fact is not surprising considering that it was acquired as an organized, systematic body of knowledge.) For example, Subject-A had an elaborate minitheory about the use and organization of space between buildings. His first sentences on viewing the site were as follows: (PF3) S-A: ...

v To my family vi vii List of publications This thesis is based on the following publications referred to in text as paper I, paper II, paper III and paper IV. A peptide-based vector for efficient gene transfer in vitro and in vivo. Solid formulation of cell-penetrating peptide nanoparticles with siRNA and their stability in simulated gastric conditions. Resubmitted to J. Control. Release. Deli...

We determine the indexes of all orthogonal Grassmannians of a generic 16dimensional quadratic form in I q . This is applied to show that the 3-Pfister number of the form is ≥ 4. Other consequences are: a new and characteristic-free proof of a recent result by Chernousov–Merkurjev on proper subforms in I q (originally available in characteristic 0) as well as a new and characteristic-free proof ...
