Such materials are difficult to subject to machining, subsequent to the forming operation, with a view to achieving the assemblable form of the component.
Conceptually, an isothiourea-catalyzed reaction of an acetic acid bearing an α-leaving group with a suitably electron-deficient α,β-unsaturated ketimine 1 9 would result in Michael addition/lactamization with subsequent elimination to form the pyridones 2 (Scheme 1). 10 Subsequent N- to O-sulfonyl migration 11 would allow the pyridines 3 to be accessed directly in one pot.
It is conceivable that the spontaneous deacylation may generate an electrophilic intermediate (from the acceptor) which is susceptible to nucleophilic addition by another monomer (the donor) in the subsequent step to form the dimeric product.
Here we report the step-wise development of AVE sub-domains from individual cells of the implanting blastocyst and their subsequent coalescence to form an asymmetrical domain of AVE at the distal tip of the egg cylinder.
Recent studies on amyloid disease-related proteins such as β-amyloid and prion have pointed out that conformational alternation and subsequent aggregation to form amyloid fibrils play a key role in such fatal diseases.
A subsequent attempt to form a caretaker government failed because it could not win a vote of confidence.
We assessed infants' persistence after receiving different types of information and their subsequent ability to form label-object or function-object associations.
A variety of methods for fabrication of microfluidic devices with subsequent bonding to form channels include photolithography-lift-off ([Schoning et al. 2005]), soft lithography ([Kwakye and Baeumner 2003]), and laser ablation ([Eswara and Dutt 1974]).
The business has remained there ever since, and it has added four subsequent buildings to form the integrated structure that is now called the Marshall Field and Company Building.
Because of the well recognized involvement of Aβ in forming fibrils and amyloid plaques, we also evaluated the effects of H13,14 substitution of Aβ40 on its subsequent ability to form fibrils, bind to Aβ fibrils, and label amyloid plaques.
Subsequent attempts to form single crystals produced only MgSeO4·7H2O.
