Traffic Accident size can be expressed as the number of deaths and/or the number of injured. Accident size is the one of the important indices to measure the level of safety of transportation facilities. Factors such as road geometric condition, driver characteristic and vehicle type may be related to traffic accident size. However, all these factors interact in complicate ways so that the interrelationships among the variables are not easily identified. A structural equation model (SEM) is adopted to capture the complex relationships among variables because the model can handle complex relationships among endogenous and exogenous variables simultaneously and furthermore it can include latent variables in the model. In this study, we use accident data having 1867 traffic accident rewarded in Vadodara city since 2013 to 2017 and estimate relationship among exogenous factors and traffic accident size. The model suggests that road factors, vehicle factors, victim factors and time factors are strongly related to the accident size.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
