Study Cum Research on Effect of Addition of Organic and Inorganic Acids in Naturally Bonding Sand Used in Metal Casting

NUST Journal of Engineering Sciences, 2014
We have investigated the effect of addition of some of the inorganic and organic acids, in the naturally bonding sands taken from the bank of river Ravi, Lahore, Pakistan, on quality of casting and on mechanism of their reinforcement in the moulding sand.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Optimisation of Continuous and Pulsed Cooling in Injection Moulding Processes [PDF]

, 2007
The concept of pulsed cooling in injection moulding involves cycling the flow of coolant in order that cooling only takes place as and when it is required, as opposed to continuous cooling, where the coolant in run through the channels throughout the ...

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

BMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.
