1. Effect of high temperature and recovery from stress on crop–weed interaction
ABSTRACT Biotic and abiotic stresses, either individually or in combination, may affect soybean growth and development negatively, besides competitiveness with weeds. This study aimed at evaluating the effect of heat stress and plant recovery on crop–weed interaction by analyzing growth variables. Experiments were set up as replacement series of soybean wi

2. Psathyrella atlantica (Agaricales: Basidiomycota), a new species from Brazil
ABSTRACT Psathyrella atlantica is described based on material collected in an Atlantic Forest fragment in the state of Pernambuco, Northeast Brazil. It is characterized by slender, whitish and caespitose basidiomata; pileus with orange, small and floccose-squamulose veil remnants; presence of a persistent but fragile-membranous annulus; basidiospores 5-7 ×

3. A new oligolectic bee species of the genus Rhophitulus Ducke (Hymenoptera, Andrenidae) from South Brazil
ABSTRACT The genus RhophitulusDucke, 1907 is a large and complex group of bees of the tribe Protandrenini comprising small, slender, mostly black ground-nesting species that are restricted to South America. We describe a new species of Rhophitulus from Parque Nacional São Joaquim, Urubici, state of Santa Catarina, Brazil. Rophitulus ater sp. nov. is distinc

4. A new species of the sharpshooter genus Dasmeusa (Hemiptera: Cicadellidae: Cicadellini) from Central Amazon
ABSTRACT A new species of the genus Dasmeusa Melichar, 1926 is described and illustrated from specimens collected in the State of Amazonas, Northern Brazil. Dasmeusa imperialis sp. nov. can be distinguished from the five known species of the genus, as well as from those of closely related genera, by the following combination of features: dorsum yellow with o

5. Taxonomic revision of Megalothoraca (Diptera: Richardiidae) with description of a new species, synonyms and new combination
ABSTRACT A taxonomic revision of Megalothoracha Hendel, 1911 is provided, including a description of Megalothoraca rosalyae Wendt, sp. nov. from Colombia. The genus encompasses large species from Colombia, Ecuador, Peru and Bolivia (new record), and each species was described based either on males or females. These species can be diagnosed by long and slende

6. Impact responses of slender composite plates for bird-strike testing of fan blades
Abstract Bird-strike failure of fan blades is one of the basic challenges for the safety of aircraft engines. Simplified slender blade-like plates are always used to evaluate the impact-induced damage mechanism at design stage. One undesirable issue is the failure at the root of clamped slender plates, which cannot recover the real case of twisted blades. Fo

7. Analytical determination of the vibration frequencies and buckling loads of slender reinforced concrete towers
Abstract This study focused on improving the design of slender structures with reinforced concrete (RC) telecommunication towers as the main application. Analytical procedure based on Rayleigh’s method to compute the first natural vibration frequency and the critical buckling load was development. All the nonlinearities present in the system were considere

8. Improved finite element of a transversely cracked straight beam with an additional degree of freedom
Abstract A new finite element with an additional degree of freedom at the crack location is derived for static bending analysis of a transversely cracked uniform slender beam. In the simplified computational model, which is based on Euler-Bernoulli's theory of small displacements, the crack is represented by a linear rotational spring connecting two elastic

9. Numerical fundamentals and interactive computer graphics system for the nonlinear analysis of planar frames
Abstract Recent scientific and computational advances have facilitated the analysis of slender structural systems subject to instability. With the employment of more sophisticated numerical tools and algorithms, it is possible to accurately determine the critical points (limit and bifurcation loads) as well as the post-critical behavior of the structural sys

10. Description of Scoloplos maranhensis sp. nov. (Orbiniidae, Annelida) from tropical Brazilian mangrove
ABSTRACT A new species of orbiniid, Scoloplos maranhensis sp. nov., is described from a tropical mangrove (Quebra Pote, state of Maranhão, Brazil, 02°41.344’S; 44°12.604’W) along with a comparative table with all Scoloplos species. The main distinguishing characters of S. maranhensis sp. nov. are thorax with 12 chaetigers, neuropodia from first chaeti

11. Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry & Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or

12. Contulma vascaina sp. n. (Insecta: Trichoptera: Anomalopsychidae), a new species from Rio de Janeiro state, southeastern Brazil
ABSTRACT The caddisfly genus Contulma Flint, 1969, with 30 described species, is endemic to the Neotropics. In addition to the five species currently recorded from Brazil, a new species of Contulma is described and illustrated in this work. Contulma vascaina sp. n. is similar to C. sana Jardim and Nessimian, 2011 in prominent, slender and rod-like posterolat
