A phenocryst is an early forming, relatively large and usually conspicuous crystal distinctly larger than the grains of the rock groundmass of an igneous rock. Such rocks that have a distinct difference in the size of the crystals are called porphyries, and the adjective porphyritic is used to describe them.
Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America. The species is best known as the source of aequorin (a photoprotein ), and green fluorescent protein (GFP) ; two proteins involved in bioluminescence.
As her oddly observant tweets continue going viral -- many have been featured on famous Instagrams like @thefatjewish and @fuckjerry--Twitter user @teenybiscuit keeps churning out her signature ...
The first commercial products involving two-dimensionally periodic photonic crystals are already available in the form of photonic-crystal fibers, which use a microscale structure to confine light with radically different characteristics compared to conventional optical fiber for applications in nonlinear devices and guiding exotic wavelengths.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
Photonic crystal fibers are a special types of optical fibers that has contain air holes distributed in specific patterns around a solid or hollow core. Due to their high sensitivity, inherent flexibility, and small diameters, they can be used in a variety of situations requiring high robustness and portability.
Once the crystals have formed, a centrifuge is used to separate the molasses. From there, different steps follow depending on the type of cane sugar in question: unrefined, raw or refined.
Being generally herbivorous, and mostly passive plankton-feeders, they live their lives according to the currents and find food by floating ventral-side up; some may more actively forage, at times. [3] They ensnare planktonic food by entangling it in a mucous web [8] measuring up to 5 cm wide—many times larger than their own bodies. If ...
