Scientists determine early Earth was a ‘water world’ by studying exposed ocean crust（图）
Scientists early Earth water world’ exposed ocean crust
2020/3/13
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say, after analyzing oxygen isotope data from ancient ocean crust now exposed on land in Australia. The findi...
Many of an organism's traits are influenced by cues from the environment. These features are known as phenotypically plastic traits, and are important in allowing the organism to cope with unpredictab...
RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Fog detection, Radiative Transfer Model SBDART Indo-Gangetic plain Brightness temperature difference threshold Middle Infrared Thermal Infrared
2019/2/28
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...

Fast Radio Bursts Twists Shouts Scientists Cosmic Blasts
2018/1/31
An international group of astronomers has found that the Cornell University-discovered fast radio burst FRB 121102 – a brief, gigantic pulse of radio waves from 3 billion light years away – passes thr...
Bee Buzzes Could Help Determine How to Save their Decreasing Population
Bee Buzzes Save Decreasing Population
2017/7/21
According to recent studies, declines in wild and managed bee populations threaten the pollination of flowers in more than 85 percent of flowering plants and 75 percent of agricultural crops worldwide...

Super Resolution Imaging Stem Cell Future
2017/3/14
Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible.Understanding a stem cell’s fate – the type...
OU Geologist Collaborates on Study to Determine Mechanism Associated with Fault Weakening in Earthquakes
OU Geologist Collaborates on Study Mechanism Associated Fault Weakening Earthquakes
2015/5/25
A University of Oklahoma structural geologist and collaborators are studying earthquake instability and the mechanisms associated with fault weakening during slip. The mechanism of this weakening is c...
Application of Neuro-Genetic Algorithm to Determine Reservoir Response in Different Hydrologic Adversaries
neuro-genetic models reservoir response
2015/3/1
The hydrologic adversaries like high magnitude storms, extreme dryness, aridity, more than normal
demand for water etc. often cause a huge stress on the storage structures such as reservoirs and che...
Integrating Water Quality Modeling with GIS to Determine Management Strategies: A Study of Fort Gordon, GA

2014/11/12
Land managers of the Fort Gordon military installation in Augusta, GA were in need of a tool which
would predict the effects to water quality produced by changes in land use as well as predict
impac...
COMBINING PROBABILITY OF EMPTINESS AND MEAN FIRST OVERFLOW TIME OF A DAM TO DETERMINE ITS CAPACITY
Stochastic simulation dam process behavior analysis
2014/11/12
Probabilistic considerations have been practiced in determining the capacity of a dam after the
introduction of probability theory of dams by P. A. P. Moran (1954). Various researchers determined
th...
Environmental selection and resource allocation determine spatial patterns in picophytoplankton cell size
Environmental selection picophytoplankton cell
2014/4/2
Here we describe a new trait-based model for cellular resource allocation that we use to investigate the relative
importance of different drivers for small cell size in phytoplankton. Using the model...
When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a min...
