Nine matched pairs of cephalosporins and their 1-carba-1-dethiacephalosporin analogues have been compared with regard to microbiological activity, beta-lactam carbonyl infrared absorption, and aqueous stability. In general the microbiological activit

Protein kinase C (PKC) is a family of closely related serine and threonine kinases. Overactivation of some PKC isozymes has been postulated to occur in several diseases states, including diabetic complications. Selective inhibition of overactivated P

A redeveloped direct drilling chisel coulter is described. The new version has retained the agronomically desirable features displayed by its original experimental counterpart, particularly when operating in dry soil or climatic conditions. In additi

A mechanism capable of holding a coulter at specified depths in soil is described. Rolling, positive depth regulation is pivoted over the leading point of the lateral wings of the coulter on a common walking beam axle. This places depth sensing as cl

A series of structurally unique 1-carba-1-dethiacephems is described. The structural stability of the 1-carba-1-dethiacephem nucleus was essential for the preparation of this series of 3-quaternary ammonium carbacephems. The known p-nitrobenzyl 7 bet

To extend the range of surface conditions under which an experimental non-rolling direct drilling coulter could operate, several trash clearance modifications were evaluated. The emphasis of the modifications was on cutting, deflecting, and/or holdin

It is not capable of reference to the hypergeometric type and so requires methods peculiar to itself. The principal difficulty in the solution of the equation consists in the determination of a number, the characteristic exponent, which appears in th
