Dhansak consumed for three days after the death of a near one. And dhansak is used to break this abstinence on the fourth day. Hence, dhansak is never prepared on auspicious occasions like festivals and weddings. Dhansak is made by cooking mutton cubes with a mixture of various lentils and vegetables. Traditionally, four lentils (arhar dal, Bengal gram or chana dal, red masoor dal and brown masoor dal) are used, but one or more of the lentils may be omitted or substituted. The vegetables include potato, tomato, brinjal, pumpkin and fenugreek leaves: again, substitutions, such as squash for pumpkin, and sweet
Ultrashort pulse specific pulse shapes). If the pulse shaper is fully calibrated, this technique allows controlling the spectral phase of ultrashort pulses using a simple optical setup with no moving parts. However the accuracy of MIIPS is somewhat limited with respect to other techniques, such as frequency-resolved optical gating (FROG). Several techniques are available to measure ultrashort optical pulses. Intensity autocorrelation gives the pulse width when a particular pulse shape is assumed. Spectral interferometry (SI) is a linear technique that can be used when a pre-characterized reference pulse is available. It gives the intensity and phase. The algorithm that extracts the intensity
