Riscos no trabalho com andaimes [PDF]
, 2010 Os andaimes podem ser vistos como estruturas simples e de fácil utilização mas, na realidade, trata-se de uma estrutura complexa que, habitualmente, passa para segundo plano, comparativamente à importância dada às restantes actividades que compõem uma ...

Zoonoses and Public Health, EarlyView.ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

Reproductive and Perinatal Outcomes of Embryo Transfer in Elite Hanwoo Cows
Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.Reproductive outcomes following embryo transfer in Elite Hanwoo cows differed by embryo production method. OPU‐IVF was associated with higher abortion, increased birth weight of male calves and greater dystocia risk, whereas MOET resulted in more favourable calving outcomes, highlighting the importance of embryo production strategy and periparturient ...

One and Two Polarizations, Membrane Creation and Objects Complexity in P Systems [PDF]
, 2005 We improve, by using register machines, some existing universality results for specific models of P systems. P systems with membrane creation are known to generate all recursively enumerable sets of vectors of non-negative integers, even when no region ...

Biotropica, Volume 58, Issue 2, March 2026.Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

Tissue P Systems with Cell Division [PDF]
, 2004 In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { the possibility to divide ...

On Descriptive Complexity of P Systems [PDF]
, 2005 In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where the number of steps of a computation is not sufficient to evaluate ...

Anti‐Predation and Size‐Dependent Gas Exchange Functions of Amazonian Architect Cicada Towers
Biotropica, Volume 58, Issue 2, March 2026.Clay towers built by cicada nymphs before metamorphosis are poorly understood. We experimentally show that towers of the Amazonian cicada Guyalna chlorogena reduce predation risk and exhibit size‐dependent growth responses to gas exchange obstruction, supporting their interpretation as adaptive extended phenotypes.
