Believing in death and life after death has been the base of religion. Az far az the foundation of all religions is united. hence it we could be stated that there is no diversity among religions. Eventually we result in the notion that the human creation has not been aimless and they will return to God. the only difference in the quality and the way every single person travels along this journey.\nFundamentally, human being travels along life in the material world and life after departure, thus looks forward to achieving the results and consequences of their actions to dwell eternally in the vicinity of God.
The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for assisting auto-ignition. The spark timings are changed in steps of 3 degrees and the suitable timing that offers better phasing is called optimum Spark timing. From the investigation it is found that the hydrous methanol suits perfectly with HCCI engine and the water content present in the hydrous methanol helps to phase the combustion perfectly and to change the rate of combustion. The investigation also proves that the hydrous methanol operation reduces NO and smoke extremely low which is not possible by the direct injection CI engine. The water content present in the hydrous methanol helped to control the timing of auto ignition and helped to run HCCI engine smoothly. Therefore, it is beneficial to use hydrous methanol in internal combustion engines.
One of the main presumptions of agency theory is that company managers (employees) and stockholders (employers) have contradictions in benefits and managers do not necessarily make decisions for the benefits of stockholders. Thus the present research has studied the relation Cash Flows, Earnings Opacity and Stock Price Crash Risk . This research has been carried out in the statistical population of the firms accepted in Tehran Stock Exchange during the years between 2008 and 2012 among 148 active companies there as our statistical sample. To test the hypotheses we have used a logistic regression model. The research findings showed that earnings opacity and operating cash flow sensitivity have a positive and meaningful effect on the risk of stock price crash.
GPR is a non-destructive method revealing electrical discontinuity in low depths (less than 50 meters) using ground penetration radar. Radar performs this act by generating, transmitting, reflecting, propagating, and receiving discontinuous pulses through electromagnetic energy with the frequency of Mega or Giga Hertz. In the present study, water leak in buried metal and plastic pipes are investigated using radar. The purpose of the study is to examine the performance of GPR device to detect leaks. Also, necessary efforts during leak occurrence and the effect of metal and plastic pipes quality are investigated as the affective factor causing leaks. Finally, the gathered data are analyzed using AutoCAD software.
The indigenous fish Garra mullya from Kanher dam was studied in relation to the seasonal variation in Muscle Glycogen content. The variation observed was related to the season, habitat, sex and maturation cycle of the fish. The percentage of glycogen obtained in both male and female species were more or less identical.
