New Developmental NiCrMo Alloys
CORROSION 1983, 1983Abstract Experimental results on laboratory and production material are given for two new alloys. The first, alloy is an improvement over most versatile corrosion-resistant alloys available today. The second alloy was developed specifically for improved corrosion resistance in commercial phosphoric acid production. This alloy is intended

New Developmental Clock Discovered
Science, 1997DEVELOPMENTAL BIOLOGYBiological clocks all typically keep to a 24-hour schedule, which is logical because it helps keep organisms in tune with the normal day length. But now scientists have come across a new kind of biological clock, one that not only has a much shorter cycle, but also appears to be driven by a different kind of mechanism.

New Insights and New Issues in Developmental Neurotoxicology
NeuroToxicology, 2002Here, I will review accumulating evidence that during the developmental period of synaptogenesis, also known as the brain growth spurt period, neurons are very sensitive to specific disturbances in their synaptic environment. During this period, abnormal increases in NMDA glutamate (Glu) receptor activity triggers excitotoxic neurodegeneration, and ...

Developmental transitions: So what's new?
British Journal of Developmental Psychology, 1998Structural approaches to development, such as Piaget's stage theory, have proved to be problematic in dealing with developmental transitions. More promising in this respect are models of qualitative change that address macroscopical phase shifts in non‐linear dynamical systems that arise from quantitative changes at the microscopical level.

Overview: developmental toxicology—new directions
Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2011AbstractSince regulatory agencies began implementing the use of standardized developmental toxicology protocols in the mid‐1960s, our knowledge base of embryo‐fetal development and technologies for experimentation has grown exponentially. These developmental toxicology protocols were a direct result of the thalidomide tragedy from earlier that decade ...
