CLOUD SCALES. “Cloud active aerosols, i.e., cloud condensation nuclei (CCN) and ice nuclei (IN), can modify cloud microstructure, precipitation forming processes, and the meteorological and radiative responses of clouds and the atmosphere. These effects impact both the atmospheric circulation systems and the thermodynamic and radiative energy budgets over a cascade of scales from local to global.” https://lnkd.in/dR5c8TB View in LinkedIn

“COSMIC RAYS alter the ionosphere-Earth electric current which, in turn influences cloud properties through charge effects on droplet freezing and other microphysical processes. Significance level of correlations. 67% for cosmic rays and low clouds, 98% for solar irradiance and low clouds.” https://lnkd.in/d2cyRBr View in LinkedIn

SAND CHARGES. “Grains in desert sandstorms spontaneously generate strong electrical charges; likewise volcanic dust plumes produce spectacular lightning displays. Charged particle clouds also cause devastating explosions in food, drug and coal processing industries.” https://lnkd.in/dW6wCcD View in LinkedIn

CHARGED DUST. “As long ago as 1850, Michael Faraday commented on the peculiarities of the production and discharge of electric charges during sandstorms, a phenomenon repeatedly rediscovered over the intervening century and a half. Similarly, sand is known to become strongly electrified by helicopters traveling in desert environments, producing spark and explosion hazards, and the issue even has implications for missions to the Moon and to Mars, where charged dust degrades solar cell viability and clings to spacesuits, limiting the lifetime of their joints.” http://arxiv.org/pdf/1003.5188 View in LinkedIn

SNOWFLAKES. “Ice can form homogeneously by either freezing liquid water, or directly through vapor deposition to the crystalline phase. As is the case for the homogeneous nucleation of liquid water surface tension effects imply that for a given supersaturation an ice-embryo must reach a critical size. For ice-embryo’s smaller than this critical size an increase in the crystal size implies an increase in the change of the free energy of the system.” http://www.mpimet.mpg.de/fileadmin/staff/stevensbjorn/teaching/skript-5.pdf View in LinkedIn

FRAGMENT FROM NATURE contemplates the human facial structure which enables language and emotional communication. The musculature and structure of the human face seems excessively complex. Darwin’s The Expression of the Emotions in Humans and Animals (1872) is a classic, wherein he observed his screaming child and analyzed the muscles responsible for the behavior. Since then, thinking about the human face has matured, and the reasons behind our complex mask are revealing themselves. View in LinkedIn

DRY NOSES. “Haplorhini (the haplorhines or the "dry-nosed" primates, the Greek name means "simple-nosed") is a clade containing the tarsiers and the simians (or anthropoids).” https://lnkd.in/dReYf85 View in LinkedIn

DRY NOSES TRAITS. “The haplorhine upper lip, which has replaced the ancestral rhinarium found in strepsirrhines, is not directly connected to their nose or gum, allowing a large range of facial expressions. Their brain to body ratio is significantly greater than the strepsirrhines, and their primary sense is vision. Haplorhines have a postorbital plate, unlike the postorbital bar found in strepsirrhines. Most species are diurnal (the exceptions being the tarsiers and the night monkeys).” https://lnkd.in/dReYf85 View in LinkedIn
