I will use Blender as artist, since Blender and its community are part of my life."; and "I realized that the lab community size is not enough to support a so expensive project". [ 13 ] In December 2018, a new repository, based on Bastioni's last version (1.6.1a), aiming at Blender 2.80 compatibility, was opened on GitHub with the project name ...
Failure in polymer components can occur at relatively low stress levels, far below the tensile strength because of four major reasons: long term stress or creep rupture, cyclic stresses or fatigue, the presence of structural flaws and stress-cracking agents. Formations of submicroscopic cracks in polymers under load have been studied by x ray ...
Due to the activated nature of the cyclic carbon–carbon triple bond, many alkyne addition-type reactions such as the Diels–Alder, 1,3-dipolar cycloadditions and halogenation may be performed using very mild conditions and in the absence of the catalysts frequently required to accelerate the transformation in a non-cyclic system. In addition ...
Cyclic compounds may or may not exhibit aromaticity; benzene is an example of an aromatic cyclic compound, while cyclohexane is non-aromatic. In organic chemistry, the term aromaticity is used to describe a cyclic (ring-shaped), planar (flat) molecule that exhibits unusual stability as compared to other geometric or connective arrangements of ...
There are not enough workers paying into the system to fund the benefits of all the retirees. Declining fertility rates and increasing life expectancies are causing the U.S. population to be older.
This year’s adorable list of competitors in the 2025 Puppy Bowl includes Chow Chow and Chihuahua mix Lin-Manuel Furanda, a three-legged Doberman Pinscher named Maxx, a Lab puppy called Meatball ...
In organic chemistry, a cycloaddition is a chemical reaction in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity". The resulting reaction is a cyclization reaction.
The macrocyclic effect is the high affinity of metal cations for macrocyclic ligands, compared to their acyclic analogues. [7] [8] The high affinity of macrocyclic ligands is thought to be a combination of the entropic effect seen in the chelate effect, together with an additional energetic contribution that comes from the preorganized nature of the ligating groups (that is, no additional ...
