Questions 1. Describe the hallmarks of scientific research. There are eight characteristics of the hallmarks of scientific research which are purposiveness‚ rigor‚ testability‚ replicability‚ precision and confidence‚ objectivity‚ generalizability and parsimony. Purposiveness is the manager has started the research with a definite aim or purpose. Rigor is connotes carefulness‚ scrupulousness‚ and the degree of exactitude in research investigation. Testability is a property that applies to

the famed Tsinghua University as a student majoring in Precision Instruments and Mechanics‚ with scores at the National University Entrance Examinations ranking the first in the region and the fifth in the province. In Tsinghua University I found the gateway to the beautiful garden of Mechanics. What I saw in its Micron and Nanotechnology Center‚ such as electric generators only a few microns large‚ and various laser devices in precision measurement‚ carried me away completely. When I learned

The sample peaks were seen to match with corresponding standard drug peaks. Some additional peaks observed in the sample chromatograms. These peaks‚ however‚ did not interfere with the Barnidipine and internal standard peak (Figure 1 and 2). 4.5.4 Accuracy: The absolute recovery of Barnidipine was determined by comparing the response factor of the drug obtained from the plasma with response factor obtained by the direct injection of Barnidipine in mobile phase at three different levels. Recovery studies

Trigonometrical Survey) benchmark is a permanently fixed reference survey station (or point)‚ having known elevation with respect to a standard datum (mean sea level). These are established all over India by Survey of India department with greater precision. A benchmark value is quite essential at any survey area‚ especially for reduction of observed sea level with respect to mean sea level or chart datum (CD). While carrying out bathymetric survey of a survey area‚ the datum referenced values thus

the processing precision is not high‚ it will produce noise. When the two parallel rollers rotate in opposite directions‚ the rolling distance of general milling system is 0.1~0.8mm‚ the heart grinding system is 0.01~0.05mm. Roller body is longer‚ the two ends of the hole processing and the middle is not processed‚ due to the machining error of the roller and the material of the roller body is not uniform‚ the grinding roller is not balanced and the vibration is generated. The accuracy of the roller
