A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

open access: yesAgricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

Dynamics of immune response and drug resistance in malaria infection

open access: yesMalaria Journal, 2006
Background Malaria parasites that concurrently infect a host compete on the basis of their intrinsic growth rates and by stimulating cross-reactive immune responses that inhibit each others' growth.

Symbiots: Conceptual interventions into energy systems [PDF]

open access: yes, 2009
Symbiots set out to examine values such as ease-of-use, comfort, and rationality assumed within conventions of ‘good design’, in order to expose issues related to energy consumption and current human- (versus eco-) centered design paradigms. Exploring re-

Norman and Nietzsche: The Political Project of Lindsay's The Magic Pudding

open access: yesAustralian Journal of Politics &History, EarlyView.
Australian artist and writer Norman Lindsay (1879–1969) wrote 11 novels and two children's books, one of which—The Magic Pudding first published in 1918—remains a national classic. This article argues that readers and critics have long misunderstood Lindsay's intention in writing this lengthy cartoon‐story about the adventures of Bunyip Bluegum in ...

Commerce, coalitions, and global value chains: Coordinated and collective lobbying on trade

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Global value chains (GVCs) have connected firms in complex networks within and across national borders. However, political economy models often assume away production linkages and thus fail to explain pervasive and diverse trade coalitions cutting across industries and firms. I develop a GVC‐centered framework where production linkages through

Structure of ectoparasite communities of Nyctalus species (Chiroptera: Vespertilionidae) in the Zhiguli State Nature Reserve and Samarskaya Luka National Park (European Russia)

open access: yesNature Conservation Research: Заповедная наука
The ectoparasites of the bats (Chiroptera) often act as carriers of infectious agents dangerous to animals and humans. This determines the relevance of studying ectoparasite communities.

Moderna visão da evolução da virulência A modern view of the evolution of virulence

open access: yesRevista de Saúde Pública, 1995
Atualmente considera-se que parasitas devem evoluir em direção à virulência reduzida, pois patógenos virulentos apresentam maiores probabilidades de levarem seus hospedeiros e eles próprios à extinção.
