Jurnal Dinamika Global, 2019 Is the Middle East on a path to regional war? One hundred years after the conclusion of World War I, many of the same factors the preceded wars in Europe seem to be in place in the region today: increased arms sales, social and political unrest, and increasing conscription.

Advanced Engineering Materials, EarlyView.High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Cotton leaf gas exchange responses to irradiance and leaf aging
Biologia Plantarum, 2015 Cotton (Gossypium hirsutum L.) net photosynthetic rate (PN) decreased with leaf age and low irradiance, and the interaction of these factors might lead to decreased yields mainly in crops with a high plant density.

The Arabidopsis Book, 2012 The presence of neighboring vegetation modifies the light environment experienced by plants, generating signals that are perceived by phytochromes and cryptochromes. These signals cause large changes in plant body form and function, including enhanced growth of the hypocotyl and petioles, a more erect position of the leaves and early flowering in ...
