New Biopesticides for IPM and Organic Production
Phaseout of the fumigant methyl bromide, restrictions on organophosphates, environmental problems with neonicotinoids and pyrethroids, pest resistance, and the exponential growth of organic agriculture has created a market for alternatives (Weston et al. 2004; Moran 2010; Quarles 2011ab; 1993a). Beneficial nematodes, Bacillus thuringiensis (BT), and a large array of fungi, viruses, and bacteria...
متن کاملSmall-step and big-step semantics for call-by-need
We present natural semantics for acyclic as well as cyclic call-by-need lambda calculi, which are proved equivalent to the reduction semantics given by Ariola and Felleisen. The natural semantics are big-step and use global heaps, where evaluation is suspended and memorized. The reduction semantics are small-step and evaluation is suspended and memorized locally in let-bindings. Thus two styles...
متن کاملBiopesticides: An ecofriendly approach for pest control
An ecofriendly alternative to chemical pesticides is biopesticides, which encompasses a broad array of microbial pesticides, biochemicals derived from micro-organisms and other natural sources, and processes involving the genetic incorporation of DNA into agricultural commodities that confer protection against pest damage. Biopesticides fall into three major classes. The potential benefits to a...

This editorial introduces the new, online, open-access journal Research Involvement and Engagement. The journal considers manuscripts on any aspect of the engagement or involvement of patients, carers or members of the public in design, delivery and dissemination of research in health or social care. We support the involvement of patients in the production of the journal, as co-authors, as revi...
متن کاملSeparation Logic for Small-Step cminor
Cminor is a mid-level imperative programming language; there are proved-correct optimizing compilers from C to Cminor and from Cminor to machine language. We have redesigned Cminor so that it is suitable for Hoare Logic reasoning and we have designed a Separation Logic for Cminor. In this paper, we give a small-step semantics (instead of the big-step of the proved-correct compiler) that is moti...
