Alternately soak in saline containing 0.5% phenol for 24-48 hours in a refrigerator. 3. After cooling‚ filter through filter paper until completely clear. 4. Insert a few drops of antiserum in bottom of a small test tube and carefully add some of the filtrate down the side of the tube to form a layer of antigen above antiserum. 5.

NOISE CONTROL OF TWO STROKE PETROL ENGINE USING AQUA SILENCER SYNOPSIS Air pollution is most important from the public health point of view‚ because every individual person breathes approximately 22000 times a day‚ inhaling about 15 to 22 Kg of air daily. Polluted air causes physical ill effect decides undesirable aesthetic and physiological effects. Air pollution can be defined as addition to our atmosphere of any material‚ which will have a deterious effect on life upon our planet. The main pollutants contribute

synthesized adsorbent. The adsorbent must be poured slowly to ensure it mixed well with CPO and prevent numerous bubbles formed. Then‚ the mixture is heated until it reaches 150 °C and allows stirring vigorously for an hour until bleaching is completed. Filtration After bleaching is done‚ the spent adsorbent is separated from the bleached palm oil (BPO) by filtration using filter paper no.50. Filtration will be carried out in the oven at the temperature of 80 °C for a period of 22 hours. Once

If the light is a far distance from the plant‚ the strength of light for the plant would be very weak‚ therefore decreasing the rate of photosynthesis. Another alternate but simple way is to change the colored light by comparing different colored filters and their effects to change the rate of photosynthesis. Some colors like red and blue increase the rate of photosynthesis‚ while colors like yellow and green decrease the rate of photosynthesis. Many people would choose the factors that have just

Introduction The photosynthesis lab is designed to quantify photosynthesis‚ enabling a number of variables to be tested for their effects on photosynthetic rate. The production of oxygen‚ is used as an indirect measure of photosynthetic activity.The lab allows the examination of the effects of different wavelengths of light on photosynthetic activity. The other aspect of the lab includes
