INTERACTION BETWEEN GROWTH STRATEGIES AND PHOSPHORUS USE EFFICIENCY IN GRASSES FROM SOUTH AMERICA NATURAL GRASSLANDS

Interaction between growth strategies and phosphorus use efficiency in grasses from South America natural grasslands

ABSTRACT South American natural grasslands are composed of several species with different growth strategies, with variations in specific leaf area (SLA), leaf dry matter content (LDMC), little tikes specific root length (SRL) and specific root area (SRA).The objective of this study was characterizing in grasses cultivated with different levels of p

Mineral preservatives in the wood of Stradivari and Guarneri.

Following the futile efforts of generations to reach the high standard of excellence achieved by the luthiers in Cremona, Italy, by variations of design and plate tuning, current interest is being focused on differences in material properties.The long-standing question whether the wood of Stradivari and Guarneri were treated with wood preservative

Singularities in Structural Optimization of the Ziegler Pendulum

Structural optimization Vita of non-conservative systems with respect to stability criteria is a research area with important applications in fluid-structure interactions, friction-induced instabilities, and civil engineering.In contrast to optimization of conservative systems where rigorously proven optimal solutions in buckling problems have been

Evaluation of Sub-Kilometric Numerical Simulations of C-Band Radar Backscatter over the French Alps against Sentinel-1 Observations

This study compares numerical simulations and observations of C-band radar backscatter in a wide region (2300 km 2 ) in the Northern French Alps.Numerical simulations were performed using a model chain composed of the SAFRAN meteorological reanalysis, the Crocus snowpack model and the radiative transfer model Microwave Emission Model for Layered Sn

The identification of two Trypanosoma cruzi I genotypes from domestic and sylvatic transmission cycles in Colombia based on a single polymerase chain reaction amplification of the spliced-leader intergenic region

A single polymerase chain reaction (PCR) reaction targeting the spliced-leader intergenic region of Trypanosoma cruzi I was standardised by amplifying a 231 bp fragment in domestic (TcIDOM) strains or clones and 450 and 550 bp fragments in sylvatic strains or clones.This reaction was validated using 44 Video Interface blind coded samples and 184 no
