Principal building stones generally used in the United States are limestones, marbles, granites, and sandstones. Other stones such as serpentine and quartzite are used locally but to a much lesser extent. Stone, in general, makes an excellent
building material, if properly selected on the basis of experience; but the cost may be relatively high.
The properties of stone depend on what nature has provided. Therefore, the designer does not have the choice of properties and colors available in some of the manufactured building units.
Corrosion of ferrous metals is caused by the tendency of iron (anode) to go into solution in water as ferrous hydroxide and displace hydrogen, which in turn combines with dissolved oxygen to form more water. At the same time, the dissolved ferrous hydroxide is converted by more oxygen to the insoluble ferric hydroxide, thereby allowing more iron to go into the solution. Corrosion, therefore, requires liquid water (as in damp air) and oxygen (which is normally present dissolved in the
Melt Processing Melt processing is the most important, most economical way of shaping plastics. It can be used for those thermoplastics with melting points and viscosity low enough not to subject die materials to excessive temperatures and stresses.
(a) Melt Processing of Thermoplastics: The raw material to be processed is usually supplied in the form of regular shape and even-size granules, because this makes quantity metering easier and quicker and leads to more uniform and predictable heating.
Understand the process flow on how to manufacture the product. Identify the hazards from its process step (task). Decide who might be harmed and how. Evaluate the risks and decide on precautions. Record your findings and implement them 6. Review your assessment and update if necessary. Plastic Toys Production Process Flow: Fig: process flow of toys production

Management of the building process is best performed by the individuals educated and trained in the profession, that is, architects and engineers. While the laws of various states and foreign countries differ, they are consistent relative to the registration requirements for practicing architecture. No individual may legally indicate to the public that he or she is entitled to practice as an architect without a professional certificate of registration as an architect registered in the locale in which the project is to be constructed.
The simplest building system consists of only two components. One component is a floor, a flat, horizontal surface on which human activities can take place. The other component is an enclosure that extends over the floor and generally also around it to provide shelter from the weather for human activities.
The ground may serve as the floor in primitive buildings. In better buildings, however, the floor may be a structural deck laid on the ground or supported above ground on structural members, such as the joist and walls in Fig.
Effect greenhouse What are greenhouse gases (GHG)? Greenhouse gases (GHGs) trap heat within the earth’s atmosphere, contributing to the ‘greenhouse’ effect and causing global warming. These gases include carbon dioxide, methane, nitrous oxide, and water vapor. Industry, including manufacturing, is the second largest global emitter of human-created GHGs. Much of industrial GHG emissions are due to the burning of fossil fuels for heat and power generation.
Why should I care about GHGs?
This article is about learning how to prepare a textile/garment sewing process maintenance checklist and the way to accomplish this procedure as periodic maintenance.
SEWING MAINTENANCE CHECKLIST Many Retail, Brand-name Marketing, Mail Order, and Sourcing Companies are visiting existing and potential Contractor sewing facilities and evaluating their sewing capabilities for producing quality products for their customers. In many cases, they even rate the vendor and give the plant a grade based on their observations during their visit.
