Speed and grade increment during cardiopulmonary treadmill testing : impact on exercise prescription
(2019) [Artículo de periódico]Background: Maximal oxygen uptake (VO2max) and both first (VT1) and second (VT2) thresholds have been used as reference points for exercise prescription in different populations. Objective: We aimed to test the hypothesis ... -
Spermatic abnormalities of piracanjuba Brycon orbignyanus (Valenciennes, 1849) after cryopreservation
(2011) [Artículo de periódico]O objetivo deste trabalho foi verificar a presença de anormalidades espermáticas no sêmen de Brycon orbignyanus após a criopreservação. Dez machos com quatro anos de idade e que apresentavam características reprodutivas ... -
Spermatic characteristics and sperm evolution on the subfamily Stevardiinae (Ostariophysi: Characiformes : Characidae)
(2011) [Artículo de periódico]A monofilia e filogenia dos membros do Clado A (sensu Malabarba & Weitzman), mais tarde redefinido e nomeado Stevardiinae (sensu Mirande), é suportada por dados morfológicos e moleculares. Aqui são examinadas, descritas e ... -
Sperm cell capacitation status of ram semen after cooling
(2022) [Artículo de periódico]Background: The use of conventional artificial insemination (AI) in sheep production is usually associated with lower fertility rates when frozen semen is used. Cooled ram semen has been an alternative over frozen semen ... -
Spermiogenesis and spermatozoa ultrastructure in five species of the Curimatidae with some considerations on spermatozoal ultrastructure in the Characiformes
(2003) [Artículo de periódico]Spermiogenesis in the curimatid species, Steindachnerina insculpta, Cyphocharax gillii, C. modestus, C. spilotus, and Potamorhina altamazonica, is characterized by lateral development of the flagellum, nuclear rotation, ... -
Spermiogenesis and spermatozoa ultrastructure in the Serrasalminae (Ostariophysi: Characiformes) with further evidence on the relationships of the piranhas and pacus
(2009) [Artículo de periódico]A ultraestrutura dos espermatozoides e espermiogênese foram estudadas nas espécies Piaractus mesopotamicus, Mylossoma duriventre, Serrasalmus maculatus e Metynnis mola de Serrasalminae, sendo dois padrões distintos ... -
Sperm quality of the Amazon catfish Leiarius marmoratus (Gill, 1870) after cold storage
(2014) [Artículo de periódico]This study aimed at assessing the sperm quality of the Amazon catfish, Leiarius marmoratus ¸ after refrigeration without extenders. After capturing the animals and stripping of semen, the following parameters were analyzed: ... -
Spetroscopic monitoring of active galactic nuclei from CTIO. II. IC 4329A, ESO 141-G55, Arakelian 120, and Fairall 9
(1996) [Artículo de periódico]The results of an intensive monitoring campaign on the Seyfert 1 galaxies IC 4329A and ESO 141-G55 are presented. Variability was detected in both continuum and broad e issjon line fluxes, and the cross-correlation analysis ... -
Spherical wave array based positioning for vehicular scenarios
(2020) [Artículo de periódico]Smart vehicles are emerging as a possible solution for multiple concerns in road traffic, such as mobility and safety. This work presents radio localization methods based on simultaneous direction of arrival (DOA), time-delay, ... -
Sphingosines derived from marine sponge as potential multi-target drug related to disorders in cancer development
(2015) [Artículo de periódico]Haliclona tubifera, marine sponge species abundant in Brazilian coastline, presents only a few papers published in the literature. Recently, we have reported the isolation of two modified C18 sphingoid bases: (2R,3R,6R,7 ... -
Spider diversity in a rice agroecosystem and adjacent areas in southern Brazil
(2009) [Artículo de periódico]Spiders are one of the most numerous groups of terrestrial predators and these are found in diverse environments such as agroecosystems and nearby areas. Research on spider diversity in agroecosystems is important for ... -
Spider species composition in the tree-shrub strata of riparian forests and its microhabitats in southern Brazil
(2016) [Artículo de periódico]The composition of the spider fauna of riparian forests is insufficiently known. These forests, adjacent to both aquatic and terrestrial environments, are recognised as having important ecosystem functions. We compare the ... -
Spider trait assembly patterns and resilience under fire-induced vegetation change in south brazilian grasslands
(2013) [Artículo de periódico]Disturbances induce changes on habitat proprieties that may filter organism’s functional traits thereby shaping the structure and interactions of many trophic levels. We tested if communities of predators with foraging ... -

Spina bifida, diplomyelia and multiple malformations in a Texel lamb
(2021) [Artículo de periódico]This report described the clinical and pathological aspects of open spina bifida and diplomyelia along with multiple congenital malformations in a Texel lamb. Clinically, paresis of the thoracic limbs, paralysis of the ... -
Spinal cord anaplastic meningioma with extra-neural metastasis in a cat
(2018) [Artículo de periódico]Meningiomas are the most frequent neoplasms involving the brain in dogs and cats, and are occasionally observed in the spinal cord. They cause compression of the central nervous system; however, do not infiltrate the ... -

Spin-coating process evolution and reproducibility for power-law fluids
(2014) [Artículo de periódico]A distinct development of an exact analytical solution for power-law fluids during the spin-coating process is presented for temporal and spatial thickness evolution, after steady state conditions are attained. This solution ... -
Spin-density-wave instabilites for imperfectly nested fermi surfaces : application to bedt-ttf salts
(1996) [Artículo de periódico]We discuss criteria for determining the optimal nesting vector from the maximum of the zero-field susceptibility for imperfectly nested Fermi surfaces. In particular, we present results for some of the bis(ethylenedithio) ... -
Spin-glass freezing in Kondo-lattice compounds
(2001) [Artículo de periódico]A theory is presented that describes a spin-glass phase at finite temperatures in Kondo-lattice systems with an additional Ruderman–Kittel–Kasuya–Yosida interaction represented by long range, random couplings among localized ...
