2.0 Plastic Waste Management Disposal of plastic waste is a serious concern in India. New technologies have been developed to minimize there adverse effect on the environment. Currently world wide accepted technology used for the plastic disposal is incineration. However‚ the incinerators designed poorly‚ releases extremely toxic compounds (chlorinated dioxins and furans) therefore‚ facing strong opposition from various non-government organizations. In India to introduce a safer disposal technology

C. Central Composite Design As PBD considers only main effects and ignores the interactions among the factors‚ therefore‚ a new design is required. Central composite design (CCD) is type of experimental design‚ which was first described by Box and Wilson (1951). Nowadays it is widely used in response surface methodology (RSM; discussed in the next section of the review) for building a second order (quadratic) model for the response variable without using a complete three-level factorial experiment

The addition of just a little drops of cinnamon essential oil to 100 ml approximately 3 ounces of carrot broth which was then refrigerated can prevent the growth of the foodborne pathogenic Bacillus cereus for at least 60 days in a study that is published in August 2003 issue of the

After determining that it was a Gram negative single bacillus‚ biochemical tests performed and their purpose and results are shown in table and flow chart form.

The corn gluten was hydrolyzed by Alcalase enzyme (a bacterial protease produced by a selected strain of Bacillus licheniformis) that was chosen among five commercial enzymes examined. The optimum process conditions for hydrolysis and solubilization were obtained as 30 g L–1 substrate mass concentration‚ 2.5 mL L–1 enzyme concentration‚ 55 °C and pH 8. Under

Measles: is an infection of the respiratory system caused by a virus‚ Symptoms: include fever‚ cough‚ runny nose‚ red eyes and a rash. Measles: is spread through respiration‚ the contact with any infected person in any way‚ including sex‚ saliva‚ or mucus‚ can cause infection making it highly contagious. It lasts from two to four days prior‚ until two to five days following the onset of the rash. Signs: and symptoms of measles include four-day fevers and the three Cs — cough‚ coryza (head cold)
