Sustainable Flooring
Sustainable flooring is produced from sustainable materials (and by a sustainable process) that reduces demands on ecosystems during its life-cycle. This includes harvest, production, use and disposal. It is thought that sustainable flooring creates safer and healthier buildings and guarantees a future for traditional producers of renewable resources that many communities depend on. Several initiatives have led the charge to bring awareness of sustainable flooring as well as healthy buildings (air quality). Below are examples of available, though sometimes less well-known, eco-friendly flooring options. The Asthma and Allergy Foundation of America recommends those with allergies to dust or other particulates choose flooring with smooth surfaces – such as hardwood, vinyl, linoleum tile or slate. In the U.S., the Building for Energy and Environmental Sustainability (BEES) program of the National Institute of Standards and Technology (NIST) provides a one-stop source of life cycle ...

Bamboo Flooring
Bamboos are a diverse group of evergreen perennial plant, perennial flowering plants making up the subfamily (biology), subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch language, Dutch or Portuguese language, Portuguese language, which originally borrowed it from Malay language, Malay or Kannada language, Kannada. In bamboo, as in other grasses, the internodal regions of the Plant stem, stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody plant, woody xylem is also absent. The absence of secondary growth wood causes the stems of Monocotyledon, monocots, including the Arecaceae, palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cork Oak
''Quercus suber'', commonly called the cork oak, is a medium-sized, evergreen oak tree in the section ''Quercus'' sect. ''Cerris''. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period. It endures drought and makes little demand on the soil quality and is regarded as a defence against desertification. Cork oak forests are home to a multitude of animal and plant species. Since cork is increasingly being displaced by other materials as a bottle cap, these forests are at risk as part of the cultural landscape and animal species such as the Iberian lynx are threatened with extinction. Description General appearance and bark The cork oak grows as an evergreen tree, reaching an average height of or in rare cases up to 25 m and a tru ...

Building Engineering
Architectural engineers apply and theoretical knowledge to the engineering design of buildings and building systems. The goal is to engineer high performance buildings that are sustainable, economically viable and ensure the safety health. Architectural engineering, also known as building engineering or architecture engineering, is an engineering discipline that deals with the technological aspects and multi-disciplinary. The responsibilities of an architectural engineer are designs, analyzing, and altering plans, or structures. They also assist team members with project objectives budgets and timelines. What it is required to be an architectural engineer is a bachelor's degree master's degree or/and professional engineering license and current knowledge of industry trends, technology, codes and regulation. From reduction of greenhouse gas emissions to the construction of resilient buildings, architectural engineers are at the forefront of addressing several major challenges of t ...

Coconut Timber
Coconut timber is a hardwood-substitute from coconut palm trees. It is referred to in the Philippines as coconut lumber, or coco lumber, and elsewhere additionally as cocowood or red palm It is a new timber resource that comes from plantation crops and offers an alternative to rainforest timber. Background Coconut timber comes from farmed plantations of old coconut palms. The coconut palm was planted as a crop in large plantations throughout the tropics in the early half of the 20th century in order to harvest the coconut fruit. The tree bears fruit until approximately 70 years of age, at which point it is considered to have reached the end of its economic life and is felled to make way for future crops. Each year, several million palms are felled throughout the tropics. Traditionally, the trunks have been wasted by-products from this process. Only in very recent years have people begun to explore the potential commercial uses for this vast, alternative supply of timber. This l ...

Polyethylene Terephthalate
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins. In 2016, annual production of PET was 56 million tons. The biggest application is in fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym ''PET'' is generally used in relation to packaging. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). PET consists of repeating (C10H8O4) units. PET is commonly recycled, and has the digit 1 (♳) as its resin identification code (RIC). T ...

Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32-million metric tons of rubbers are produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, Seal (mechanical), seals such as O-rings and gaskets, hoses, Belt (mechanical), belts, Rubber mat, matting, and flooring. They offer a different range of physical and chemical properties, so can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects, thermal stability and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History of synthetic rubber The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, create ...

Styrene-butadiene
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed worldwide. About 50% of car tires are made from various types of SBR. The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with the thermoplastic elastomer, styrene-butadiene block copolymer, although being derived from the same monomers. Types of SBR SBR is derived from two monomers, styrene and butadiene. The mixture of these two monomers is polymerized by two processes: from solution (S-SBR) or as an emulsion (E-SBR). E-SBR is more widely used. Emulsion polymerization E-SBR produced by emulsion polymerization is initiated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber Tree
''Hevea brasiliensis'', the Pará rubber tree, ''sharinga'' tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family Euphorbiaceae originally native to the Amazon basin, but is now pantropical in distribution due to introductions. It is the most economically important member of the genus '' Hevea'' because the milky latex extracted from the tree is the primary source of natural rubber. Description ''H. brasiliensis'' is a tall deciduous tree growing to a height of up to in the wild, but cultivated trees are usually much smaller because drawing off the latex restricts the growth of the tree. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged. The leaves have three leaflets and are spirally arranged. The inflorescence include separate male and female flowers. The flowers are pungent, creamy-yellow and have no petals. The fru ...

Dunamis Therapy And Fitness
In philosophy, potentiality and actuality are a pair of closely connected principles which Aristotle used to analyze motion, causality, ethics, and physiology in his '' Physics'', '' Metaphysics'', ''Nicomachean Ethics'', and '' De Anima''. The concept of potentiality, in this context, generally refers to any "possibility" that a thing can be said to have. Aristotle did not consider all possibilities the same, and emphasized the importance of those that become real of their own accord when conditions are right and nothing stops them. Actuality, in contrast to potentiality, is the motion, change or activity that represents an exercise or fulfillment of a possibility, when a possibility becomes real in the fullest sense. These concepts, in modified forms, remained very important into the Middle Ages, influencing the development of medieval theology in several ways. In modern times the dichotomy has gradually lost importance, as understandings of nature and deity have change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
