The interior structure of rotating black holes 2. Uncharged black holes [PDF]

, 2011
(Abridged) A solution is obtained for the interior structure of an uncharged rotating black hole that accretes a collisionless fluid. The solution is conformally stationary, axisymmetric, and conformally separable, possessing a conformal Killing tensor ...

A ocorrência de fluxos no perfil vertical do vento na baixa atmosfera e seu efeito na intensidade do índice "K" The occurrence of streams in the lower-atmosphere vertical wind profile and of their effect to intensity of the "K" index

Revista Brasileira de Meteorologia, 2007
Neste estudo objetivou-se caracterizar a influência dos fluxos/Jatos de Nível Baixo (JNB) nos níveis de 850 e 950 hPa com o índice "K". O mecanismo associado aos fluxos/JNB realiza um transporte de calor e vapor de água, aumentando o conteúdo de umidade ...

Modeling the gravitational potential of a cosmological dark matter halo with stellar streams [PDF]

, 2016
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the host system. We select and study narrow stellar streams formed in a Milky-

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Macroalgas de riachos da Serra da Prata, leste do Estado do Paraná, Sul do Brasil Stream macroalgae from Serra da Prata, eastern Paraná State, Southern Brazil

Acta Botânica Brasílica, 2008
Estudos florísticos das comunidades de macroalgas lóticas no Brasil são quase que exclusivamente baseadas em material do Estado de São Paulo. Informações sobre macroalgas de riachos são escassos no Estado do Paraná.

A note on centrifugation for improving freshwater invertebrate sample conservation

Acta Biologica, 2020
Sorting of freshwater invertebrate samples is best done while the animals are still alive. However, sorting in the field generally means less overall sampling can be done in the allotted time.
