1.2 Advantages of powder metallurgy Powder metallurgy is one of the popular manufacturing process now a days due to some fabulous advantages, these are described as below, 1. The powder metallurgy eliminates or minimize machining i.e. very little or no scarp is produced during P/M process. 2. P/M enables close dimensional tolerances- near- net shape possible.
The nanotechnology potentially makes the human to rendering to recent and increasing hazards due to some individual properties such as its very small size and high ratio of area to mass. Nanotechnology is the competent invention of materials and systems in nanometer length scale, and exploits the rising properties and phenomenon which have been developed in nano scale. The word “nano” means 10-9, so a nanometer is one-billionth of a meter. One description of nanoscience is the study of atoms, molecules and substance, the size of which is in the range of about 1 to 100 nm (nanometer)[1,2]. To understand in better ways, an individual human DNA molecule has a diameter of 2 to 12 nm, hair is of the order of 10,000 to 50,000 nm and viruses usually
Summary: Laser hair removal is considered as a good technique that can get you rid of unwanted hairs. In countless ways, laser hair removal in Delhi is much better than other hair reduction approaches, including electrolysis, waxing, shaving, tweezing or depilatory creams. It can yield long-lasting effects, unlike many of the procedures on this list. It takes just a couple of treatments, dissimilar to the unending ritual of shaving or waxing. If you are fatigued of these practices, then using a laser grasps an advantage over your existing short-term approaches of taking away undesirable hair.
The methods of industrial agriculture are techno science, economic, and political. The Industrial farming system was “developed decades after World War II”. This system was designed to chemically invest food production. This was done by featuring single crop-farms and animal production factices. This way of production is necessary because it’s a more efficient way to feed people.
The advantages of the Vickers hardness test are that extremely accurate readings can be taken, and just one type of indenter is used for all types of metals and surface treatments. Although thoroughly adaptable and very precise for testing the softest and hardest of materials, under varying loads, the Vickers machine is a floor standing unit that is rather more expensive than the Brinell or Rockwell machines. For aluminium alloys Rockwell B scale is used because aluminium is softer than
Furthermore, Obama used figurative language in the whole of the speech. Figurative language makes a speech become more vivid and attractive. “You 'll need the knowledge and problem-solving skills you learn in science and math to cure diseases like cancer and AIDS, and to develop new energy technologies and protect our environment. You 'll need the insights and critical-thinking skills you gain in history and social studies to fight poverty and homelessness, crime and discrimination, and make our nation fairer and more free. You 'll need the creativity and ingenuity you develop in all your classes to build new companies that will create new jobs and boost our economy.” Obama uses parallelism in this paragraph.
So much so that nearly all areas of life revolve around the use of technology. The insurmountable value that technology has for increasing the efficiency of simple and complex tasks is unquestionable. However, some of the technologically inspired ‘aesthetic cosmopolitans’ explore the pros and cons of technology for humans on a global scale. The artwork titled Truck Babies by Patricia Piccinini (5) examines the often blurred relationship between humans and technology. As technology has become more evident in everyday life, Piccinini aims to comment on the relationship that children of the 21st century have with technology and whether or not it is ethically right.
Globalization have the important role in the developing countries has certain advantages such as technological process. It has a lot of benefit in our daily life. It helps the country prevent poverty problems, creating job opportunities for the people, periphery countries depend heavily on the develop countries for raw materials, food and oil. That can be benefited the other country and it decreased the possibility of war among the countries. Many developing countries do benefited from the globalization.
Sustainable construction is the creation and responsible management of a healthy built environment based on resource efficient and ecological principles. Creating and operating buildings are matters that account for about 40% of global annual energy consumption, and therefore, an important aspect of sustainable construction is to become market responsive, and integrate the supply chain while minimizing waste. The whole process of construction would therefore engage all stakeholders of the construction industry. Concerns and Difficulties of Sustainable Construction Three issues are of utmost concern while abiding by the philosophy of sustainable construction: • Different building projects are made for different purposes. Depending on the purpose of the building, the actual effect of the sustainability practices adopted may vary at different stages of construction and use.
3.1.1Toxicity profile assessment: MTT colorimetric assay: A colorimeteric cleavage assay that helps in assessing cell survival and proliferation, also it can aid in quantifying macrophage-mediating cytotoxicity. MTT assay is a highly sensitive and reproductive method, it doesn’t require presence of radioactive compounds, easy to perform and quantify and it’s a rapid method. (Ferrari et al., 1990) A study was conducted on doxorubicin (DOX) and doxorubicin poly(N-isopropylacylamide-co-acrylic aid) (PNA) conjugates to assess their cytotoxicity
