This study aimed to assess the relationship between an uphill time-trial (TT) performance and both aerobic and anaerobic parameters obtained from laboratory tests. Fifteen cyclists performed a Wingate anaerobic test, a graded exercise test (GXT) and a field-based 20-min TT with 2.7% mean gradient. After a 5-week non-supervised training period, 10 of them performed a second TT for analysis of pacing reproducibility. Stepwise multiple regressions demonstrated that 91% of TT mean power output variation ( ...

Objetivou-se determinar os modelos que melhor descrevem a relação entre as dimensões lineares e a área foliar da mangueira, cultivar Tommy Atkins, além de estabelecer o fator de correção. A pesquisa foi conduzida na Fazenda Experimental da Universidade Federal Rural da Amazônia, na vila de Cuiarana, município de Salinópolis. Foram analisadas de 90 a 150 folhas, em 11 árvores de um campo experimental, determinando-se o comprimento e a largura máxima das folhas. A área foliar real foi determinada ...

Susisuchus anatoceps is a neosuchian crocodylomorph lying outside the clade Eusuchia, and associated with the transition between basal and advanced neosuchians and the rise of early eusuchians. The specimen MPSC R1136 comprises a partially articulated postcranial skeleton and is only the third fossil assigned to this relevant taxon. Thin sections of a right rib and right ulna of this specimen have been cut for histological studies and provide the first paleohistological information of an advanced ...

This paper presents an experimental study about the effects of elevated temperatures on the residual mechanical properties of concrete incorporating selected plastic waste aggregates (PWAs). Six different concrete mixes were prepared: a reference concrete (RC) made with natural aggregates (NAs) and five concrete mixes with replacement ratios of 7.5% and 15% of natural aggregate by three types of polyethylene terephthalate (PET) plastic waste aggregate (CPWA). Specimens were exposed to temperatures of ...

Expansion joints are current equipment applied to almost every type of bridge with relatively high maintenance costs. Furthermore, their service life is generally short (often below 10 years) and lower than the bridge expected service life (over 50 years). In this paper, the results of an inspection campaign of 150 expansion joints in road bridges, the first comprehensive survey of the kind, are presented. They allow knowing and characterizing more properly the expansion joints installed in Portuguese ...

Abstract The Romualdo Formation (Araripe Basin) is worldwide known for the large number of well-preserved fossils but the dinosaur record is rather scarce. Here we describe a new coelurosaur, which is the first tetrapod recovered from the basal layers of this stratigraphic unit that consist of dark shales. Aratasaurus museunacionali gen. et sp. nov. is known by an incomplete but articulated right hind limb with the distal portion of the femur, proximal half of tibia and incomplete pes. The new species ...

Due to the success of various triazoles that entered the pharmaceutical market and are still being used in medicines, many companies and research groups have shown interest in developing new methods of synthesis and biological evaluation ...

Therefore, the internal house environment is influenced by building typology and ventilation system.

Catchment geomorphology is one of the most important factors governing runoff and erosion. However, its complexity is difficult to describe accurately; thus, for simplicity, many studies assume hillslopes with a uniform sloping profile. The influence of this simplification on estimating the rainfall-runoff and sediment loss processes is not well understood. In an effort to improve our understanding, this study relies on laboratory experiments using a movable rainfall simulator and a 6-m-long, 3- ...

The Crato Formation paleoflora is one of the few equatorial floras of the Early Cretaceous. It is diverse, with many angiosperms, especially representatives of the clades magnoliids, monocotyledons and eudicots, which confirms the assumption that angiosperm diversity during the last part of the Early Cretaceous was reasonably high. The morphology of a new fossil monocot is studied and compared to all other Smilacaceae genus, especially in the venation. Cratosmilax jacksoni gen. et sp. nov. can be ...
