When a cell phone goes off in a classroom or at a concert, we are irritated, but at least our lives are on the road, however, irresponsible cell phone users are more than irritating: They are putting our lives at risk. Many of us have witnessed drivers so distracted by dialing and chatting that they resemble drunk drivers, weaving between lanes, for example, or nearly running down pedestrians in crosswalks. A number of bills to regulate use of cell phones on the road have been introduced in state legislatures, and the time has come to push for their passage. Regulation is needed because drivers using phones are seriously impaired and because laws on negligent and reckless driving are not sufficient to punish offenders.
ABSTRACT:- Electromagnetic Pulse generation technology has matured to the point where Electro -magnetic bombs are becoming technically feasible, with uses warfare. The development of these weapons allows there use in a non nuclear way.
Human being is a characteristics species among all living species that distinguish itself from all other living species by its ability to magnify and extend its own capabilities. Earlier, the human being has been described as a tool utilizing other animals for carrying out the work generally ascribed by him for himself. The capabilities of man along with his desire for knowledge and improvement leads to the development of a device called “A machine”. A machine, as per one of the definitions given in ‘Oxford English Dictionary’ is “An apparatus for applying mechanical power consisting of a number of interrelated parts, each having a definite function.” The evolution of machine is attributed to the propagating power of machine which is inherited from its ancestor machines. Existing machine tool makes the pathway for the manufacturing of more advanced machine tools which successively serves to accelerate the evolution of new machine tools.
Absract Carbendazim (methyl-2-benzimidazole carbamate), a metabolite of benomyl, is one of the most widespread environmental contaminants of major concern to human and animal reproductive health. The present investigation was undertaken to study the possible protective effect of linseed oil on carbendazim induced testicular toxicity. Adult albino male rats of the Sprague Dawley strain were administered with carbendazim (100 mg/(kg /day orally) . The control animals received vehicle (corn oil) alone. Also, four other groups of rats were treated by vitamin E (Vit E) (200mg/kg /day orally), carbendazim + Vit E, linseed oil (1.5 g/kg/day, orally), or carbendazim + linseed oil. All the treatments were continued for 48 days. After the treatment period, animals were euthanized, blood samples were taken, prostate and seminal vesicles were removed and weighed. Testes were also quickly removed, encapsulated and utilized for the estimation of the following parameters: sperm count, motility, viability, and abnormalities. Malondialdehyde and reduced glutathione, superoxide dismutase, and glutathione peroxidase anti oxidant biomarkers activities were estimated in the testes homogenate. Activities of testicular acetylcholine esterase and lactate dehydrogenase enzymes as well as serum testosterone levels were also determined.

Aerogel is one of the most fascinating solids ever known to man. It was first discovered in the late 1930s be Steven Kistler, and later improved on by many different scientist. As the worlds lightest solid it has many different properties engineers try to take advantage of by mixing it with various elements, and seeing if they get the results they need. One of the key aspects of Aerogel is its thermal properties which is good for insulation usage.
