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 the amplitude of ultrashort pulses. To accurately control the pulse, a full characterization of the pulse spectral phase is a must in order to get certain pulse spectral phase (such as transform-limited). Then, a spatial light modulator can be used in the 4f plane to control the pulse. Multiphoton intrapulse interference phase scan (MIIPS) is a technique based on this concept. Through the phase scan of the spatial light modulator, MIIPS can not only characterize but also manipulate the ultrashort pulse to get the needed pulse shape at target spot (such as transform-limited pulse for optimized peak power, and other
