This study was designed to examine the stage dependency of growth inhibition by Streptomyces sp. crude extract and to determine whether its antimalarial activity is cytostatic or cytocidal. Growth inhibition was assessed by differences in growth appearance between treated and control parasites. Using synchronized In vitro cultures of Plasmodium falciparum strain 3D7, growth inhibition was detec...

This paper deals with the analysis of images of biological tissue that involves ring structures, such as tree trunks, bivalve seashells, or fish otoliths, with a view to automating the acquisition of age and growth data. A bottom-up template-based scheme extracts meaningful ridge and valley curve data using growth-adapted time-frequency filtering. Age and growth estimation is then stated as the...

BACKGROUND Freshwater mussels remain among the most imperiled species in North America due primarily to habitat loss or degradation. Understanding how mussels respond to habitat changes can improve conservation efforts. Mussels deposit rings in their shell in which age and growth information can be read, and thus used to evaluate how mussels respond to changes in habitat. However, discrepancies...

Abstract In our previous work (Paper I), we demonstrated that coagulation instability results in dust concentration against depletion due to the radial drift and accelerates growth locally. this II), perform numerical simulations of taking into account effects backreaction gas collisional fragmentation grains. We find slowdown regulates nonlinear phase instability. The dust-to-gas surface densi...

We establish a second main theorem for algebraic tori with slow growth moving targets truncation to level 1. As the first application of this result, we prove Green–Griffiths–Lang conjecture projective spaces n + 1 $n+1$ components in context growth. Then discuss integrability ring exponential polynomials entire functions as another application.

Climate change is expected to increase the occurrence of severe droughts in tropics, and little known about its influence on tree dynamics. Tree-ring width remote sensing tools can help understand impacts climate growth. We evaluated applicability NDVI obtain phenological metrics (e.g., start, peak, end, length growth season) explored relationship with tree-ring Tectona grandis (teak). The were...

Thermal dissipation probes (the Granier method) are routinely used in forest ecology and water balance studies to estimate whole-tree transpiration. This method utilizes an empirically derived equation to measure sap flux density, which has been reported as independent of wood characteristics. However, errors in calculated sap flux density may occur when large gradients in sap velocity occur al...

We compared the water-use characteristics of co-occurring mature Quercus cerris L. and Quercus pubescens Willd. trees growing in resource-limited (mainly water) hilly habitats in Tuscany, Italy. The species differed in their distribution along soil water gradients and in their access to, and use of, water, even though the study year was wetter than average, though with a summer drought. Compare...
