in this contribution, linearized dynamic model of cumulative mass fraction (cmf) of potassium nitrate-water seeded continues mixed suspension mixed product removal (cmsmpr) crystallizer is approximated by a simplified model in frequency domain. frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. however, the cmf fr...

In this contribution, linearized dynamic model of Cumulative Mass Fraction (CMF) of Potassium Nitrate-Water Seeded Continues Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer is approximated by a simplified model in frequency domain. Frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. However, the CM...

Context. In our SCUBA survey of Perseus, we find that the fraction of protostellar cores increases towards higher masses and the most massive cores are all protostellar. Aims. In this paper we consider the possible explanations of this apparent mass dependence in the evolutionary status of these cores. We investigate the implications for protostellar evolution and the mapping of the embedded co...

Observations indicate that the central portions of the Present-Day Prestellar Core Mass Function (hereafter CMF) and the Stellar Initial Mass Function (hereafter IMF) both have approximately log-normal shapes, but that the CMF is displaced to higher mass than the IMF by a factor F ∼ 4±1. This has lead to suggestions that the shape of the IMF is directly inherited from the shape of the CMF – and...

We explore whether we can constrain the shape of the initial mass distribution of the star cluster population in M82's ∼ 1 Gyr-old post-starburst region " B " , in which the present-day cluster mass function (CMF) is closely approximated by a log-normal distribution. We conclude that the M82 B initial CMF must have had a mean mass very close to that of the " equilibrium " CMF of Vesperini (1998...

ABSTRACT Observations have indicated that the pre-stellar core mass function (CMF) is similar to stellar initial (IMF), except for an offset towards larger masses. This has led idea there a one-to-one relation between cores and stars, such whole reservoir contained in gravitationally bound core, as postulated by core-collapse model, assumed recent theoretical models of IMF. We test validity thi...

Wood decayed by brown rot fungi and wood treated with the chelator-mediated Fenton (CMF) reaction, either alone or together with a cellulose enzyme cocktail, was analyzed by small angle neutron scattering (SANS), sum frequency generation (SFG) spectroscopy, Fourier transform infrared (FTIR) analysis, X-ray diffraction (XRD), atomic force microscopy (AFM), and transmission electron microscopy (T...

We re-analyse all of the archive observations of the Ophiuchus dark cloud L1688 that were carried out with the submillimetre common-user bolometer array (SCUBA) at the James Clerk Maxwell Telescope (JCMT). For the first time we put together all of the data that were taken of this cloud at different times to make a deeper map at 850μm than has ever previously been published. Using this new, deep...

Salvage chemotherapy for metastatic breast cancer includes regimens for hormonal responsive patients and patients refractory to cyclophosphamide, methotrexate, and fluorouracil (CMF) or fluorouracil, doxorubicin, and cyclophosphamide (FAC). For hormone responsive patients, progestins, aminoglutethimide with hydrocortisone, and androgens provide second-line therapy and produce objective remissio...
