Over the last centuries, the processes of delta formation at the Mississippi River mouth slowed down as a result of the river sediment runoff decrease after flow regulation of the Missouri and Arkansas tributaries; in some parts of the deltaic plain, these processes gave way to degradation of ...

Notch ligands like Delta-like1 (Dll1), expressed on signal-sending cells, activate the Notch receptors on neighboring signal-receiving cells, where transcriptional repressors of the Hes/Hey family are induced1,2,3,4. Notch signaling has many known functions, among them regulating self-renewal ...

investigation suggests that episodic magmatic–hydrothermal events were involved in the formation process of the Dapai Fe polymetallic deposit.Pyrite and sphalerite from the Pb–Zn–Cu orebodies yield an Rb–Sr isochron age of 175.5 ± 3.3 Ma, which is regarded as the timing of Pb–Zn–Cu ...
Formation of River Deltas The formation of a river delta is a slow process. Asrivers flowtoward their outlets from higher elevations, they deposit mud, silt, sand, and gravel particles at the mouths where rivers and larger, more sedentary bodies of water meet. ...
In order to mitigate global warming, the international communities actively explore low-carbon and green development methods. According to the Paris Agreem
PCDD/Fs yield in thermal process such as municipal solid waste (MSW) incineration process is the balance or superposition of formation and destruction through heterogeneous and homogeneous pathways (Altarawneh et al. 2009; Hell et al. 2009; Lin et al. 2014). Structurally related precursors at a...
