Ingredient n°5 Humour for brands (and not just in advertisement)
This document summarizes Patricia Gallot-Lavallée's motivation for writing the book "Six ingredients that create fans". She realized she wanted to focus her career on designing experiences that generate positive emotions for people, rather than just usability. She embarked on a research project to study what creates intense fandom and devotion for certain products, experiences, etc. Over three weeks of intensive research involving collecting examples, pattern recognition, and free-flowing ideas, she identified six key ingredients that turn normal people into "screaming fans". This book aims to share those ingredients to help more things in the world create that wonderful feeling of "J'adooore".
Composites
Composites are materials made from two or more constituent materials that are combined to produce unique properties. Concrete is a common composite made of cement (binder) and gravel (reinforcement), and rebar can be added to make it stronger. Plastics composites are made of synthetic polymers like hydrocarbons and alcohols. Dental composites are synthetic resins used as restorative materials and adhesives in dentistry. Polymer composites use long chains of bonded molecules called polymers, commonly known as plastics or resins. The earliest uses of composites date back to 1500 BC by ancient Egyptians and Mesopotamians who used mud and straw mixtures for building. Later, Mong

Deforestation by Saul Mayordomo, Adrian george perez and Jose miguel perez hita Antonio Saorín Pérez-muelas
The document discusses the issue of deforestation. It notes that around 11,000 years ago, 60% of the Earth was covered in forests but now only about 1/5 of land has forests. Deforestation occurs for various reasons like using trees for fuel, clearing land for agriculture, and development. This removal of trees without replanting has led to damage of habitats, loss of biodiversity, increased carbon dioxide in the atmosphere, soil erosion, and degraded wastelands. Reforestation efforts are needed to counter the effects of deforestation.Deforestation

Polyethylene has many uses such as bags, coating ditches, food and industrial packaging, disposable nappies, serum bags, containers, pipes, bottles, and irrigation pipes. Polyethylene is recyclable and can be melted and transformed into new products like
Aluminium, titanium, biochips and biosensors
This document summarizes information about aluminium, titanium, biochips, and biosensors. It describes aluminium and titanium as lightweight metals that are abundant in nature. Aluminium is a silvery white metal commonly used in transportation, construction, and packaging. Titanium is stronger than steel and highly corrosion resistant, making it useful in aerospace applications and implants. The document also notes that biochips can perform many biochemical reactions simultaneously for screening and detection, while biosensors combine biological and physical elements to detect analytes.
Aluminium. Titanium. Biochips. Biosensors
Aluminum and titanium are described along with their properties and common uses. Aluminum is a light, silvery metal that is abundant in nature and commonly used in electricity, transportation, construction and packaging. It can be recycled infinitely without loss of properties. Titanium is also described with its discovery, properties as a transition metal, and common uses in alloys, aerospace, surgery and other industries. Biochips and biosensors are also summarized, with biochips enabling simultaneous biochemical reactions for screening and detection, while biosensors combine a biological component with a transducer and detector for analytical purposes.
ACERO Y ACERO INOXIDABLE, Natalia M. Carmen G.
The document discusses steel and stainless steel. It defines steel as an alloy of iron with carbon as the primary alloying element. Steel was first produced around 4,000 years ago and is strong, resistant to corrosion, and 100% recyclable. Stainless steel is an alloy of iron, chromium, and nickel that does not rust or stain easily. It was discovered in 1913 and is used widely in cookware, buildings, transportation and industrial equipment due to its corrosion resistance, strength and recyclability. Both steel and stainless steel can be recycled repeatedly without loss of quality, saving resources and reducing environmental impact with each recycling.
Natural rubber, synthetic rubber and neoprene rubber
This document discusses three types of rubber: natural rubber, synthetic rubber, and neoprene rubber. Natural rubber comes from latex and trees, was used by ancient civilizations, and is used today mainly for tires and hoses. Synthetic rubber is made from petroleum, was invented in 1909 as a cheaper alternative to natural rubber, and accounts for two-thirds of rubber production today. Neoprene is a synthetic rubber made from chloroprene polymerization that is chemically stable over a wide temperature range and used for products like wetsuits and boots.
Silicon y graphene
Silicon is a chemical element with an atomic mass of 14 that occurs in crystal or amorphous form. It is a semiconductor used in electronic chips, solar cells, and other technologies due to its strength, thermal conductivity, and elasticity. Graphene is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It was discovered in 2004 by Andre Geim and Konstantin Novoselov, who won the Nobel Prize. Graphene has unique properties including high strength, thermal and electrical conductivity, and transparency. Potential uses include shielding, electronics, vehicles, and information technologies.
Ardi
Ardipithecus is a genus of early hominid found in Ethiopia that lived approximately 4.4 million years ago. It is considered a descendant of Orrorin tugenensis and a direct ancestor of australopithecines. There were two species, A. ramidus and A. kadabba. A. ramidus had a skull similar in size to great apes and evidence shows it moved in a bipedal manner. New evidence from the Aramis site in Ethiopia, where a partial skeleton of A. ramidus was found, indicates through sedimentological and isotopic analysis that it lived in a river-margin forest within a savanna landscape, in
Coronary heart disease
Coronary heart disease is caused by plaque buildup in the coronary arteries that supply blood to the heart. Over many years, plaque narrows the arteries and reduces blood flow. If plaque ruptures, a blood clot can block blood flow and cause a heart attack. A heart attack occurs when an area of the heart muscle dies from lack of oxygen-rich blood. Angina is chest pain that occurs when blood flow to the heart is reduced. Coronary heart disease is the leading cause of death in the United States and lifestyle changes, medicines, and procedures can help prevent and treat it.
