The Basin and Range Province of the western United States is one of Earth’s most studied regions of continental rifting, and yet the timing and character of the onset of Cenozoic extension are still controversial. Some structural studies have concluded that extension in the Great Basin part of the Basin and Range Province is as old as 41–37 Ma (Rahl and others, 2002) or 32–30 Ma (e.g., Axen and...

Myocardial infarction is a common presentation of coronary artery disease and the leading cause of death worldwide. The present study was investigated potential resistance to ischemia-reperfusion (I/R) injuries following administration of methanolic (MeOH) extract of Scrophularia frigida (S. frigida) in isolated rat heart. Male Wistar rat hearts (n= 8-10) were isolated and allowed to equilibrat...

Introduction: Extended aeration activated sludge system has a lower sludge production than other activated sludge processes. Due to its high hydraulic retention time (HRT), the tolerance of this process is higher than the shocks caused by increased organic loading rate. The main objective of this study is to evaluate the performance of the aeration system in removing physicochemical and mi...

Let f and g be smooth multimodal maps with no periodic attractors and no neutral points. If a topological conjugacy h between f and g is C at a point in the nearby expanding set of f , then h is a smooth diffeomorphism in the basin of attraction of a renormalization interval of f . In particular, if f : I → I and g : J → J are Cr unimodal maps and h is C at a boundary of I then h is Cr in I.

Molecular microbial ecology studies have revealed remarkable prokaryotic diversity in extreme hydrothermal marine environments. There are no comparable reports of culture-independent surveys of eukaryotic life in warm, anoxic marine sediments. By using sequence comparisons of PCR-amplified small subunit ribosomal RNAs, we characterized eukaryotic diversity in hydrothermal vent environments of G...

In this study, we estimate life history parameters and abundance for a protected jaguar population using camera-trap data from a 14-year monitoring program (2002-2015) in Belize, Central America. We investigated the dynamics of this jaguar population using 3,075 detection events of 105 individual adult jaguars. Using robust design open population models, we estimated apparent survival and tempo...

There are 22 species of Hamacantha registered from all over the world, and frequently from deep-waters, only two of which had previously been reported from the SW Atlantic. Here we describe a third species for this area, Hamacantha (H.) boomerang sp. nov., collected from deep-sea coral mounds at Campos Basin (off Rio de Janeiro state). We found oxeas 271-630 µm long, diancistras in three size c...

Arabinogalactan proteins (AGP) are a class of cell surface plant peptidoglycans which have been implicated in root elongation and signal transduction pathways. AGPs function not only as markers of cellular identity but also as signaling molecules, which might initiate signal transduction. Aluminum promotes the elongation of tea (Camellia sinensis L.) roots. Although some mechanisms by which Al ...
