Nanofibers are under study as a possible drug carrier candidate. [9] [10] [70] Natural polymers such as gelatin and alginate make for good fabrication biomaterials for carrier nanofibers because of their biocompatibility and biodegradability that result in no harm to the tissue of the host and no toxic accumulation in the human body ...
Developed by the American military, the medical technology uses a microscopic apparatus made of fine polymer fibers called a scaffold. [2] Damaged cells grip to the scaffold and begin to rebuild missing bone and tissue through tiny holes in the scaffold. As tissue grows, the scaffold is absorbed into the body and disappears completely.
Depending on the desired property, a nanofabric is either constructed from nanoscopic fibers called nanofibers, or is formed by applying a solution containing nanoparticles to a regular fabric. Nanofabrics research is an interdisciplinary effort involving bioengineering , [ 5 ] molecular chemistry , physics , electrical engineering , computer ...
One of the biggest concepts introduced in 3 Body Problem is the idea of nanotechnology, and, specifically, nanofibers. The Three-Body Problem book's protagonist has this as one of his many skills ...
Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as "Human Anatomy for Artists: The Elements of Form", are written as a guide to drawing the human body anatomically correctly. [4]
As a person ages, some bones fuse, a process which typically lasts until sometime within the third decade of life. Therefore, the number of bones in an individual may be evaluated differently throughout a lifetime. In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally.
A national study discovered that teens in the United States consumed significantly less alcohol and drugs in 2024 compared to past years. Teen alcohol use has steadily decreased from 2000 to 2024 ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
