Abstract Parameters of flotation kinetics model with a gamma and a triangular distribution have been determined based on the batch coal flotation experiments. Analyses were carried out at different values of the intensity of aeration air. The results of example analyses are presented in tables and graphs form. It follows from the carried out study on the mathematical models of flotability coefficient distribution of particles of examined coal samples that the triangular distribution model is statistical equivalent to the gamma flotability distribution. The assumption of the triangular distribution enables determination of the density function of distribution of fraction in the industrial flotation machines. Knowledge of this function will allow better evaluation of the phenomena occurring in the process of enrichment. It may be one of the basic information used in the supervisory control system.

This study is an investigation of the expression of negation in the history of Greek, through quantitative data from representative texts from three major stages of vernacular Greek (Attic Greek, Koine, Late Medieval Greek), and qualitative data from Homeric Greek until Standard Modern. The contrast between two complementary negators, NEG1 and NEG2, is explained in terms of sensitivity of NEG2 μη‎ to nonveridicality: NEG2 is a polarity item in all stages of the Greek language, an item licensed by nonveridicality. The asymmetry in the diachronic development of the Greek negator system (the replacement of NEG1 and the preservation of NEG2) is explained with reference to the particulars of the uses of NEG2, specifically the inertial forces drawn by the nonnegative uses of NEG2, which being nonnegative did not experience the renewal pressures predicted by the Jespersen’s Cycle. These are its complementizer uses: (i) as a question particle, and (ii) in introducing verbs of fear complements. A viewpoint for Jespersen’s Cycle is proposed that abstracts away from the morphosyntactic and phonological particulars of the phenomenon and explicitly places its regularities in the semantics, accommodating not only for Greek, but for numerous other languages that deviate in different ways from the traditional description of Jespersen’s Cycle. The developments observed in the history of the Greek negator system agree with current generative theories of syntactic change, regarding the notions of up-the-tree movement.

Rejecting some old misconceptions (such as the “pulling” gravitation that ravaged classical physics) the Inertial-Gravitational theory supported by the Micro-quanta paradigm incorporates both the relativistic concepts of Mass - Momentum - Energy and the quantic Inertial Model of the particle mass. The flux of micro-quanta supports primarily the physical interaction that generates the Inertial forces defined by Newton. Scholars believing that Inertial forces originate from the properties of the empty space, do not pertain to the community of physicists believing on Newton’s Inertial Law. This great ancient physicist admitted he was unable to explicit the physical nature of his Law of Inertia (“Hypotheses non fingo”). However, marking the difference between “empty” and “absolute” space, he remained in his conviction that some unknown physical reality originates (in the absolute space) the inertial forces upon accelerated masses. At present, Micro-quanta paradigm describes the quantic objects that generate through collisions the physical inertial forces on particles. Since the flux of micro-quanta fills all space, there is no need to refer these collisions to some external System of reference. The relative velocity between quanta and particles comes out from the momentum that micro-quanta confer to particles. By this reason the Micro-quanta paradigm defines on pure dynamical bases the relativistic formalism that Special relativity derived from kinematics, so creating flaws that produced the well known paradoxes. To reveal the micro-quanta it's not necessary to devise particular experiments. The technique of the accelerometers has given many evidences of the physical reality guessed by Newton to explain inertial forces exerted on masses. Since the action of micro-quanta is always manifested in statistical terms, classical and relativistic physics allowed to describe Inertia and Gravitation without knowing the quantic nature of these phenomena. The micro-quanta Paradigm shows in particular the proportionality between cross section and mass (ratio Au) of all particles colliding with micro-quanta. To the aim of calculating the transmission across matter of micro-quanta and neutrinos (which show the same nature) the only unknown quantity is the numerical value of the ratio Au. Recalling that micro-quanta flux fills all space, it appears also interesting to search about neutrino collisions with micro-quanta flux as possible cause of the oscillations phenomena that occur during neutrino travels across the (so called) astronomic “empty” space. A quantitative indication on the ratio Ao is found in this paper from an experimental measurement of the solar neutrino flux interacting with the Earth mass in the course of the Borexino research carried out at Gran Sasso National Laboratory.
