The theoretical formulae for thermoelectric power of metals suggested by Sondhiemer [4] and Wilson [8] have partial success in explaining the experimental findings in case of Au, Ag, Cu, K, Na, Rb and Pb under test at normal temperatures. The magnitude of thermometric power of metals calculated from the theoretical formulae is much greater than that observed directly. A partial agreement between Sondhiemer’s formula and thermodynamic relation [5] is found in meeting the experimental findings in thermocouples. Thermodynamic relation fails to meet the magnitude of thermoelectric power of individual metals, observed directly. The present communication, however, appears to be more competent to meet the experimental findings in respect of magnitude of thermo power of noble metals. The theoretical expression, true for the absolute thermo electric power of metals, is not true for the same in a thermo-couple.

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...
