In the RoboCup four-legged league, robots mainly rely on artificial coloured landmarks for localisation. As it was done in other leagues, artificial landmarks will soon be removed as part of the RoboCdoi:10.1016/0006-3002(62)90624-8Toshio Ando...

Despite advances in machine learning approaches, de novo design of collagen-based materials remains difficult. In this study, based on the natural structure of the defense collagen family of proteins, designed triple helical peptide assemblies are found to form ribbons and a variety of bundled, poro...
To minimize surface damage, gentle polishing conditions are required; low levels of force should be used, and the abrasive should not be considerably harder than the work-material. A variety of polishing machines, which have almost the same structure as a lapping device, can be used (polishing...
chemical structure itself, although only specific conformations are normally involved in its pharmacological mode of action. Moreover, a drug must also be absorbed and reach the site of action. The physicochemical properties behind drug absorption and distribution are also essential features of its ...
Cellulose, a complex carbohydrate that is the basic structural component of theplant cellwall, is the mostabundantpolymer on earth. The basic structure of cellulose and its derivatives is shown below. In unaltered native cellulose, X represents hydrogen, forming a number of pendant hydroxyl (OH) ...
Acetone structure CAS No. 67-64-1 Chemical Name: Acetone Synonyms propan-2-one;aceton;2-Propanone;(CH3)2CO;ACETONE ALCOHOL;Propan-1-one;Propanon;2-Propanon;Dimethylketal;GRAMS DECOLORIZER CBNumber: CB3130928 Molecular Formula: C3H6O
It is also one of the simplest polymers, consisting of random-length (but generally very long) chains made up of two-carbon units. You will notice some "fuzziness" in the way that the polyethylene structures are represented above. The squiggly lines at the ends of the long structure ...

The structure of armors may include ceramic plates, special fibers/textile structures, laminated/coated textiles, and composites depending on these parameters. In addition, blunt impact protection could be imparted to armors by including shock-absorbing materials. Different types of body armor used for...
