Mineral element concentrations are presented in leaf and bark material from six woody species growing at a single site on the subantarctic Auckland Islands. Foliar total mineral element concentrations range from 5.81% (Olearia lyallii) to 2.71 % (Dracophyllum longifolium), the lowest concentrations occurring in slow growing species tolerant of nutrient-poor soils. The browse preference of intro...

In this article, element free Galerkin method is used for static analysis of thin micro/nanoscale plates based on the nonlocal plate theory. The problem is solved for the plates with arbitrary boundary conditions. Since shape functions of the element free Galerkin method do not satisfy the Kronecker’s delta property, the penalty method is used to impose the essential boundary conditions. Discre...

In the present work, a generalization of the classical model of Monod accounting the influence of both delayed and instant mortalities on the dynamics of the micro-organism population is proposed. The model was analysed and compared with respect to its quality and applicability for simulation of the cultivation process of micro-organisms. Existence of a unique global positive solution of the Ca...

Bacterial community composition was monitored in four shallow eutrophic lakes during one year using denaturing gradient gel electrophoresis (DGGE) of PCR-amplified prokaryotic rDNA genes. Of the four lakes investigated, two were of the clearwater type and had dense stands of submerged macrophytes while two others were of the turbid type characterized by the occurrence of phytoplankton blooms. O...

Wheat is staple food crop for the world. Nutrient management one of important determinants yield crop. Conventional fertilizers are having several challenges in form cost, their losses environment and use efficiencies. Nanofertilizer emerging as a potential alternative to these owing small size. Nanofertilizers both macro micro nutrients have seen improvement other quality parameters nutrient c...

Micro-nutrient Fortification of Food T he High-level Expert Forum from FAO’s 192 Member Nations will discuss, deliberate and take important decisions during the World summit scheduled in Rome around the mid November 2009, the strategies to ensure that everyone has enough to eat both today and tomorrow. During last week of October AIIMS New Delhi is organising An International Workshop on Micron...

The plasmodium of Physarum polycephalum is a large single cell visible with the naked eye. When inoculated on a substrate with attractants and repellents the plasmodium develops optimal networks of protoplasmic tubes which span sites of attractants (i.e. nutrients) yet avoid domains with a high nutrient concentration. It should therefore be possible to program the plasmodium towards determinist...
