We report a hitherto unknown occurrence of ancient Neoproterozoic evaporite deposits from an allochthonous terrane in the Pan-African Gariep belt in Namibia. Low contents of Rb, Cs, Ba, Zr, Hf, Th, and U, flat chondrite-normalised rare earth element (REE) patterns, Sr/Sr ratios as low as 0.7075, Na–Cl–Br systematics of fluid inclusion leachates, and high dB values for stratiform tourmalinites, ...

Approximately 34 million years ago across the Eocene-Oligocene transition (EOT), Earth's climate tipped from a largely unglaciated state into one that sustained large ice sheets on Antarctica. Antarctic glaciation is attributed to a threshold response to slow decline in atmospheric CO2 but our understanding of the feedback processes triggered and of climate change on the other contents is limit...

Soil-transmitted helminth (STH) infections can result in a variety of negative health outcomes (e.g., diarrhea, nutritional deficiencies). Market integration (MI; participation in market-based economies) has been suggested to alter levels of STH exposure due to associated changes in diet, sanitation, and behavior, but the effects are complicated and not well understood. Some effects of economic...

The study features an analysis of 40 years of records of longitude, latitude and power (wind speed) of tropical storms and typhoons over South East Asia seas. The results demonstrate the growing intensity of the most severe events. The singular spectrum analysis of wind speed series from 1960 till 2000 identified two sub-periods of roughly similar behavior. Then, the recorded events were classi...

The prediction of the intensity, location and time landfall a tropical cyclone well advance in with high accuracy can reduce human material loss immensely. In this article, we develop Long Short-Term memory based Recurrent Neural network model to predict intensity (in terms maximum sustained surface wind speed), (latitude longitude), hours after observation period) which originates North Indian...

Soil transmitted helminths are parasitic groups of worms that live in countries with subtropical or tropical climates. In humans, when exposed to eggs larvae, they can cause infection. Stool examination is divided into qualitative and quantitative examination. Qualitative direct examination, flotation, tape, deposition, thick preparations. Kato-Katz Stoll quantitative. The purpose this study wa...

Ultraviolet spectra of the northern and southern hemispheres of Jupiter taken with the Hubble Space Telescope Faint Object Spectrograph (FOS) in May 1992 and June 1993 have been used to derive the altitude profiles of NH3 in the vicinity of the tropopause. For a given pressure level, it is shown that the vertical profile of ammonia varies with latitude and the atmospheric feature being observed...

BACKGROUND Soil-transmitted helminth (STH) infections affect more than two out of every five schoolchildren in the poorest regions of rural China, an alarmingly high prevalence rate given the low cost and wide availability of safe and effective deworming treatment. Understanding of local knowledge, attitudes, and practices regarding STH infection in rural China has until now, been sparse, altho...

This ten-year general circulation model experiment compared a simulation where land surface boundary conditions were represented by observed, present day land cover to a simulation where the surface was represented by natural, potential land cover conditions. As a result of these estimated changes in historical land cover, signi®cant temperature and hydrology changes a€ected tropical land surfa...

Abstract Two types of mid-high-latitude low-frequency intraseasonal oscillations (LF-ISOs), featuring eastward and westward propagation, have been identified over the Eurasian continent in past 37 summers (1982–2018). The propagating modes commonly a dominant periodicity 30–50 days near Ural Mountains (UM) but different origins evolutions. LF-ISO initiates eastern North America, migrates northe...
