A Spatial Analysis of Rift Valley Fever Virus Seropositivity in Domestic Ruminants in Tanzania [PDF]

open access: yes, 2015
Rift Valley fever (RVF) is an acute arthropod-borne viral zoonotic disease primarily occurring in Africa. Since RVF-like disease was reported in Tanzania in 1930, outbreaks of the disease have been reported mainly from the eastern ecosystem of the Great ...

Aerosol and Cloud Microphysical Characteristics of Rifts and Gradients in Maritime Stratocumulus Clouds [PDF]

open access: yes, 2006
A cloud rift is characterized as a large-scale, persistent area of broken, low-reflectivity stratocumulus clouds usually surrounded by a solid deck of stratocumulus.

The Rwenzori Mountains, a Paleoproterzoic crustal shear belt crossing the Albertine rift system [PDF]

open access: yes, 2015
This contribution discusses the development of the Paleoproterozoic Buganda-Toro belt in the Rwenzori mountains and its influence on the western part of the East African Rift System in Uganda.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Phlogopite-Olivine Nephelinites Erupted During Early Stage Rifting, North Tanzanian Divergence

open access: yesFrontiers in Earth Science, 2020
The North Tanzanian Divergence (NTD, eastern branch of the East African Rift) corresponds to an early stage of continental breakup. In the southern NTD, two quaternary volcanoes of the Manyara-Balangida rift (Labait, Kwaraha) have erupted primary ...

Some Like It Hot –Structural Changes in Extremophile Rubredoxin at 120 °C

open access: yesAngewandte Chemie, EarlyView.
We reveal the high temperature crystal structure of a hyperthermophilic (Pyrococcus furiosus) rubredoxin at 393 K (120 °C), together with multiple complementary structures down to 100 K. The results are compared with molecular dynamics calculations. Significant changes in H‐bonding are observed.

Assessing Origins of End‐Triassic Tholeiites From Eastern North America Using Hafnium Isotopes

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The driving processes responsible for producing the Central Atlantic Magmatic Province, the Large Igneous Province associated with end‐Triassic rifting of Pangea, remain largely debated.
