Measurements of CO 2 (direct GHG) and CO, SO 2 , NO (indirect GHGs) were conducted on-line at some of the coal-based thermal power plant in India. The objective of the study having three major objectives: to quantify the measured emissions in terms of emission coefficient per kg of coal and per kWh of electricity, to calculate the total possible emission from Indianthermal power plant, and subsequently to compare them with some previous studies. Instrument IMR 2800A Flue Gas Analyzer was used on-line to measure the emission rates of CO 2 , CO, SO 2 , and NO at 08 numbers of generating units of different ratings. Certain quality assurance (QA) and quality control (QC) techniques were also adopted to gather the data so as to avoid any ambiguity in subsequent data interpretation. For the betterment of data interpretation, the requisite statistical parameters (standard deviation and arithmetic mean) for the measured emissions have been also calculated. The emission coefficients determined for CO 2 , CO, SO 2 , and NO have been compared with their corresponding values as obtained in the studies conducted by other groups. The total emissions of CO 2 , CO, SO 2 , and NO calculated on the basis of the emission coefficients find have been found to be 511.944,2.0576,4.473,1.241 Tg respectively.

Roselle (Hibiscus sabdariffa) belongs to the family Malvaceae. The different part of roselle are the seeds, leave and calyces and these have been used for different uses. Roselle or Hibiscus sabdariffa plant is also reported to be antiseptic, aphrodisiac, astringent, demulcent, digestive, purgative and resolvent. It is used as a folk remedy in the treatment of abscesses, bilious conditions, cancer, cough, debility, dyspepsia, fever, hangover, heart ailments, hypertension, neurosis, scurvy and strangury. The fresh calyces consist of saponins, tannins, cyanogenic glycoside and other phytocochemical such as protocatechuric acid. It also contains antioxidants including flavonoids, gossypetine, hibiscetine and sadderetine. Some of the anthocyanins of roselle identified by chromatographic process include delphinidin-3-sambubioside, cyaniding-3-sambubioside and delphinidin-3-glucose. The aqueous extract and the colouring matter of the calyces are lethal to Mycobacterium tuberculosis. Fresh calyces are rich in pectin and citric acid. Aonla is known for its nutritional qualities being rich in vitamin C and tannins. Guava is a seasonal fruit and is high in pectin and vitamin A.So present investigationis undertaken to prepare jam using fresh roselle (Hibiscus sabdariffa) calyces, aonla and guava.Three samples of jam are prepared. One is prepared by using only roselle pulp. Other two are prepared by replacingroselle pulp withaonla and guava each at 50%. Overall acceptability of these sample ranges from 7.2 to 7.55.
