The crystal structure of AgEu(SO4)2 was determined by Monte Carlo method ... 10–5 K–1 in magnitude, and therefore, AgEu(SO4)2 expands almost isotropically. Upon heating in argon flow, AgEu(SO4)2 is stable up to 1053 K. ... that is evidence of good crystalline quality of AgEu(SO4)2 and uniform local environment of Eu3+ ...

The initial histologic response (2–8 hours after challenge) of previously infected animals was characterized by edema and a progressive, predominantly polymorphonuclear infiltrate. By 16 and 24 hours, the schistosomules were the foci of intense mixed cell infiltrates, and by 36 and 48 hours, dense mononuclear infiltrates ...

Some polysphinctine wasps of the genus Zatypota complete their life cycles upon theridiid host spiders. The host range of these wasps is usually species-specific, although in some less common associations more than one wasp species interacts with the same host spider. Here we describe and illustrate the polysphinctine wasps Zatypota baezae sp. n. and Zatypota mulunguensis sp. n. (Hymenoptera: Ichneumonidae), both koinobiont ectoparasitoids of the spider Anelosimus baeza (Theridiidae). The two parasitoid ...

Harvestmen are one of the largest groups of arachnids with more than 6,500 species distributed in 1,500 genera and 50 families. However, the interactions between harvestmen and arthropod-pathogenic fungi have rarely been studied. Certain previous studies report that fungal attack represents one of the most important factors for the mortality of harvestmen, but the fungus has rarely been identified, and most of the important information about the fungus-host interactions remains unrecorded. In the ...

Behavioral manipulation of hosts by parasites is important to increase the parasite fitness. Some species within the genus Ophiocordyceps, notably pathogens of ants, induce changes in the host's behavior, leading the host to die outside the colony and locking its mandibles on the edge of leaves. This study was conducted in Massif of Baturité, and for the first time, we describe the interaction between fungi and wasps in Northeastern Brazil. We found 24 specimens, eight of each species of wasp, all ...

Reducing the use of bars and the amount of material that becomes scrap is a key factor in process efficiency, reducing the need for raw material procurement. The mathematical model used considers the size of the bar, the number and size of cuts, the size of the leftovers that can be used and the size of the leftovers that are considered scrap. Based on real data from a company in ...

Abstract This study aimed to estimate the genetic diversity of three Elaeis guineensis populations in Rio Grande do Norte state, as well as to verify the decreases in effective population size. The population with the highest polymorphism was MAT (Mata) with+ 57 loci (72%), followed by RIA (Riacho) with 54 loci (68%) and HOR (Horta) with 34 loci (43.03%). The RIA population was shown to be the most genetically diverse, with Nei (h = 0.28) and Shannon (I = 0.41) diversity indices. There was high genetic differentiation ...
