Performance and Emission Improvements of 4 - Stroke Multi- Cylinder CI- Engine by Use of DMCEGM-Diesel Blends
No full textABSTRACT Dimethyl carbonate (DMC) and ethylene glycol monoacetate (EGM) are two hopeful alternative fuels as well as fuel additives to improve performance and emissions in CI engine, due to their high oxygen content. This paper presents an experimental study on their effects on the performance and emissions characteristics of CI engine. Test results show that brake thermal efficiency for the DMCEGM05 blends is higher than that of diesel blend while in the case of DMCEGM10 and DMCEGM15 blends it is lower. BSEC of DMCEGM-diesel blends show decreasing trend for increasing brake power or load. As engine load raises the values of EGT increase. Maximum EGT is measured at full load conditions for all blends. CO emissions can be remarkably reduced with the addition of DMC and EGM to diesel. Minimum CO is found for DMCEGM10 fuel. The blends of diesel with 10% DMC and EGM by volume is the best fraction for reduction of smoke and CO emissions. The obtained results show that the fuel which effectively reduces the CO emissions is less effective in reducing the NO x emissions. All these results indicate the potential of the DMC-EGM-diesel blends for clean combustion in diesel engine. The blends of diesel with 15% DMC and EGM by volume is the best fraction for reduction of smoke and CO emissions
Financial statement and Financial Analysis - An overview
No full textFinancial Information is the basis for financial planning, analysis and decision-making. It is also useful to different users who are either directly or indirectly interested in firm. Owners of firm, managers, creditors, investors, employees and tax authorities are direct users, whereas, financial analyst, researchers and trade organization are indirect users. A firm communicates financial information to these users through financial statements and report. Financial statements contain summarized information of the firm’s financial affairs organized systematically. Therefore in the present descriptive paper, the author has tried to present theoretical concepts of financial statement, financial analysis and relationship between financial analysis

HETEROSIS AND COMBINING ABILITY STUDIES IN INDIAN MUSTARD (BRASSICA JUNCEA L.)
No full text*Author for Correspondence A study was made to estimate combining ability, heterosis over mid parents (MP) and better parent (BP) with ten diverse parents and their 45 F1 s in half diallel mating design in Indian mustard for nine quantitative and quality traits were made to derive the information on the extent of heterosis over economic parent and relative magnitude of general and specific combining ability effects. On the basis of mean values, the hybrid RK 9501 x GM 2 and the parent RK 9501 were having most outstanding performance for seed yield per plant. A considerable degree of desirable and significant heterosis over mid parent (MP) and better parent (BP) was noted for crosses GM 1 x GM 3 and GM 3 x SKM 139 respectively for seed yield per plant. Significant differences were observed for both general combining ability (gca) and specific combining ability (sca) for almost all the traits studied. The high magnitude of gca and sca effects indicated the presence of both additive and non-additive gene interactions for the inheritance of different traits. Parents RK 9501,GM 1,GM 2,GM 3 and SKM 139 were observed to be good general combiners for seed yield and they also showed good general combining ability for most of the other characters, as well as on the basis of sca effects out of 45 crosses six crosses were found better for seed yield per plant viz; GM 3 x SKM 139
Current concepts on oxidative/carbonyl stress, inflammation and epigenetics in pathogenesis of chronic obstructive pulmonary disease
No full textChronic obstructive pulmonary disease (COPD) is a global health problem. The current therapies for COPD are poorly effective and the mainstays of pharmacotherapy are bronchodilators. A better understanding of the pathobiology of COPD is critical for the development of novel therapies. In the present review, we have discussed the roles of oxidative/aldehyde stress, inflammation/immunity, and chromatin remodeling in the pathogenesis of COPD. An imbalance of oxidants/antioxidants caused by cigarette smoke and other pollutants/biomass fuels plays an important role in the pathogenesis of COPD by regulating redox-sensitive transcription factors (e.g., NF-κB), autophagy and unfolded protein response leading to chronic lung inflammatory response. Cigarette smoke also activates canonical/alternative NF-κB pathways and their upstream kinases leading to sustained inflammatory response in lungs. Recently, epigenetic regulation has been shown to be critical for the development of COPD because the expression/activity of enzymes that regulate these epigenetic modifications have been reported to be abnormal in airways of COPD patients. Hence, the significant advances made in understanding the pathophysiology of COPD as described herein will identify novel therapeutic targets for intervention in COPD
