Knowledge of cloud and precipitation formation processes remains
incomplete, yet global precipitation is predominantly produced by
clouds containing the ice phase. Ice first forms in clouds warmer
than −36 °C on particles termed ice nuclei. We combine observations
from field studies over a 14-year period, from a variety of
locations...
Education as a right has taken off internationally with expanded national policies in recent years. Across Africa over 80% of countries have abolished tuition fees for primary education and several have made the leap to free secondary education as well. With decreased financial barriers keeping kids out of the classroom,...
In January-February 1971 five replicate 0.07 m² Van Veen grabs
were obtained from each of 12 stations in Arthur Harbor and nine Van
Veen grabs were obtained from two stations in nearby Bismark Strait.
The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
A continuous flow diffusion chamber (CFDC) was used to measure ice formation by
cloud particle residuals during the Cirrus Regional Study of Tropical Anvils and Cirrus
Layers-Florida Area Cirrus Experiment. These measurements were directed toward
determining the relative contributions of homogeneous nucleation, heterogeneous
nucleation, and secondary ice formation processes to...

Earth system processes exhibit complex patterns across time, as do the models that seek to replicate these processes. Model output may or may not be significantly related to observations at different times and on different frequencies. Conventional model diagnostics provide an aggregate view of model–data agreement, but usually do not...
Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...
Export economy has been interrupted in shrimp/prawn, the second largest earning source of Bangladesh due to detection of Nitrofuran in export ed prawns to the EU countries. Around 100 consignments of frozen prawn (Macrobrachium rosenbergii) were rejected at the EU borders between 2005 and 2009. Bangladesh exported shrimp and fish...
The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...
