production of carbon paper. The best kinds of ink were tested on two mediums‚ coupon bond and onion skin. They were also tested for efficiency in terms of the number of coatings needed. The carbon paper was evaluated on the basis of clarity‚ neatness of the print and general acceptability. The final sample made use of two coatings of the ink mixture using carbon black‚ with coupon bond as the medium. The pigment (carbon black) to vehicle (glycerol) ratio of 1 g : 6 mL and 1 g : 7 mL was used using

The stress concentrations for the coated hip implant showed 20 -30 % reduction in 316L Stainless steel (SS)‚ 30 % in Titanium alloy and 20 % in cobalt chromium alloy. Among them‚ Co-Cr alloy gives better reduction in stress distribution and deformation compared to Titanium alloy and 316L Stainless steel (SS). In conclusion‚ a bioactive coating has tremendous potential for improving bone integration of a wide

before giving it a chance to soak deep into the ground. Some leaves‚ known as drip tip leaves have a waxy coating to protect them. Because of the intense rain fall in the tropical rainforest‚ normal leaves would sag under the weight of all the rain and probably snap off the branches. Drip tips have long extended tips and a waxy coating to help the rainfall drip off the leaves. The waxy coating also helps protect the leaves from too much sunlight and from insects to eat the leaves. Lianas are plants

The effectiveness of lemongrass essential oil incorporated into starch based bio-coating in lengthening the shelf life of Carica papaya (Papaya) was tested through the application of different concentrations of lemongrass essential oil and starch treatment on the papayas. The Peel Color Index (PCI) of each papaya was determined 4 days after the application of starch bio-coating. Table 1: Mean Peel Color Index of Carica papaya for Day 0 and Day 4.

This particular process involves the set-up of the machines‚ the loading of the boards‚ and the actual cleaning and coating of the said boards by the machines. From the computations above‚ it is clearly illustrated that there is a disparity between the loading of the boards into the machines and the output of the cleaning and the coating machines. The loading rate exceeds that of the cleaning and coating capacities. So the capacity of the

Painting‚ anodising or plating metals are good ways to prevent their corrosion. However‚ a more reactive metal in the electrochemical series must be chosen for coating‚ especially when chipping of the coating is expected. Water and the two metals form an electrochemical cell‚ and if the coating is less reactive than the coatee‚ the coating actually promotes corrosion. Physical Porperties of Metals Traditionally‚ metals have certain characteristic physical properties: they are usually shiny (they
