In this paper, a new approach is proposed for stress state - dependent flow localization in bifurcation failure model bounded through ductile damage in dynamically loaded sheets. Onset of localized necking is considered in phenomenological way for different strain rates to draw the forming limit diagram (FLD). Using a strain metal hardening exponent in the Vertex theory related to the strain ra...

punicagranatum cv. malassaveh is one of the most desirable commercial cultivars in iran. in thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. for thispurpose, both liquid and agarmurashige and skoog (1962) (ms) medium supplemented with baat 2, 4.5, 9, 13 μm alone and in...

A phenotyping platform that generates 3D plant reconstructions was developed and applied to identify genetic loci regulating shoot architecture in the agriculturally important crop sorghum.

We consider the optimal use of information in shooting at a collection of targets, generally with the object of maximizing the average number (or value) of targets killed. The shooting problem is viewed as a Markov decision process, and the modal solution technique is stochastic dynamic programming. Information obtained about target status may or may not be perfect, and there may or may not be ...

BACKGROUND AND AIMS It is stated in many recent publications that nitrate (NO3-) acts as a signal to regulate dry matter partitioning between the shoot and root of higher plants. Here we challenge this hypothesis and present evidence for the viewpoint that NO3- and other environmental effects on the shoot:root dry weight ratio (S:R) of higher plants are often related mechanistically to changes ...

This paper describes a prime and easy-touse protocol for large-scale production of plant lets through shoot tip culture of Lantana camera, the plant having phytoremediation potential and the method is useful for the ex-situ conservation of other species important for phytoremediation. A simple micro-propagation method from nodal and shoot tip explants were reported here for Lantana camera, at c...

Research pertaining to genetic variability parameters, heritability, and genotypic, phenotypic, simple, and environmental correlations for various seedling traits in five elite advanced cotton (Gossypium hirsutum L.) lines (FH-113, FH-114, FH-941, FH-942, and FH-2015) and one check (CIM-496) was carried out during October and November 2010 under greenhouse conditions at the Cotton Research Inst...

To enhance the genetic resource base of Echinacea purpurea (L.) Moench, a tetraploid was developed by treating seeds with different concentrations of colchicine. For further multiplication, in vitro micropropagation through adventitious shoot induction and proliferation was achieved. Shoot buds were induced directly on adaxial surface of mature leaf tissues growing on MS medium supplemented wit...

The smooth cordgrass Spartina alterniflora is the foundation species in intertidal salt marshes of the North American Atlantic coast. Depending on its elevation within the marsh, S. alterniflora may be submerged for several hours per day. Previous ecosystem-level studies have demonstrated that S. alterniflora marshes are a net sink for nitrogen (N), and that removal of N from flooding tidal wat...
