Velcro

Everyone uses Velcro in some way, whether it’s on shoes or if it’s simply just to stick two things together. Velcro, which is inspired by burrs (a type of seed case or flower head), is a very famous example of biomimicry. In 1941, when Swiss engineer George de Mestral was removing burrs from his dog after a hunting trip, he decided to observe them and see how they worked. When he looked at the burrs under a microscope, George de Mestral noticed that there are tiny hooks at the end of each spine on

Iara Lema Ms. McIntosh Science 7B December 12, 2017 Biomimetic or Biomimicry: Nature's responses to human problems Many different species have had to adapt to the most adverse conditions of nature, whose solutions have been the product of biological evolution. Today our civilization faces many problems that need sustainable solutions, as science shows us, they can be inspired by the wisdom of nature. So, instead of racking our brains thinking about creative ways to solve them, we should find

Life Cycle Assessment (LCA) is a technique used to quantify environmental outcomes- energy, materials used, and released wastes- assignable to a product. It assesses the environmental impacts of their supply chain activities as a whole. By looking at the full picture of the activities, a firm such as Procter and Gamble (P&G) could view the environmental tradeoffs of product innovation. In efforts to sustain competitive advantage with their popular-selling item, disposable diapers, the use of LCA

fit one’s life style. As we go through the similarities and differences we will see that the decision will be purely based on personal preferences. Cloth diapers have changes through the years since safety pins and special folding, they now have Velcro and snap closures and are just about as quick to change as a disposable diaper. Cloth diapers come in many different styles, flat, fitted, pockets and all-in-ones. Some of the biggest downfalls with cloth diapers is the washing of the diaper and leaking

In Generation Velcro, Dorothy Woodend asks questions regarding the lack of transferable knowledge from generation to generation. She begins her essay with a personal recount of how a store clerk questioned why her son could not tie his shoes yet. The store clerk informed her that many high school students would come in to the store in need of Velcro for the same reason. Instead of taking offense to this Woodend compares it to something Jane Jacobs had wrote about a soon to come Dark Age due to a

In her article, “Generation Velcro”, Dorothy Woodend emphasises that today’s youth is ill-prepared for the harsh realities of the world because there is “loss of knowledge” (para. 5, p. 182). Woodend states that children are cradled and sheltered and are stripped of the opportunity to become self-sufficient. Woodend ponders over Jane Jacob’s words, in which the author discusses that “the loss of knowledge, once vanished, is so difficult to regain” (para. 5, p. 182). Woodend uses this to suggest

Have you ever been outside during a hot summer day and life's going great until u feel a small pinch on your arm or pulled out a pair of headphones and they're all bundled up or are enjoying a movie and and hear someone retighten there velcro shoes every minute.All these little things would just be better if we didn't have them at all or some one came up with a good solution. First of all mosquitos are one of the most annoying animals of all time with their annoying little wings and that terrible

it sounds. Made out of the bristly side of the velcro it can stick to most things. The velcro used is black and plain. There is no existing thing that is just a large velcro pad. This product is made out of many 2 inches by 4 inches velcro pads all sewn together to make a giant velcro pad. In total, the size of the individual pad is 24 inches by 40 inches. Sticky Walls can also be made to where you can have it in a special shape. Sticking the velcro to the wall may be a problem if you choose to

Inelastic bandages have shown increased pressure, and decreased comfort vs. Velcro, alongside increased prognoses (Mosti, 2015). Prenatal diagnosis of fetuses for the detection of pathogens and defects has also been a problem potentially solved by velcro. Circulating fetal nucleated cells are the most accurate form of genomic DNA determination, and nanoVelcro microchips hybridizing for detection has shown promising results. The Velcro microchips use maternal blood to collect chromosomal aberrations, gender
