Abstract:
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling. The present status of theoretical solar models is presented and discussed in relation with the observational constraints: helioseismology, lithium depletion and measured neutrino fluxes.

Abstract:
The charge transfer processes in nonpolar media are considered in the work. The nonpolar medium is regarded as a field of random forces or impulses, and this field acts on the reacting particles. The interaction of reagents with the medium is described through the function of fluctuation of the impulse of a particle of the medium with the speed of the reagent particle. When calculating the kinetic parameters of such a system, the quantum theory of charge transfer processes was used using Green's functions of the impulse density operators of the condensed medium. Analytical expressions for the kinetic parameters of the process are obtained.

Abstract:
While some people wonder why analyze the models for which assumptions are known to be false, the economists believe that they can learn a lot in that way. The article shows that the knowledge that academic economists have gained largely related to concrete cases and not with rules. Economists often do not offer general rules or theories which should be compared with empirical data, but they analyze models that are ?special theoreticall cases?, and which help the understanding of economic problems, by describing analogies between the the problem and economic models. Economic models, empirical data, experimental results, and other sources of knowledge have the same epistemological status at economists, because they provide the cases with which they can compare the specific of economic problems.

Abstract:
AbstractThis article compares the epistemic roles of theoretical models and model organisms in science, and specifically the role of non-human animal models in biomedicine. Much of the previous literature on this topic shares an assumption that animal models and theoretical models have a broadly similar epistemic role—that of indirect representation of a target through the study of a surrogate system. Recently, Levy and Currie (2015) have argued that model organism research and theoretical modelling differ in the justification of model-to-target inferences, such that a unified account based on the widely accepted idea of modelling as indirect representation does not similarly apply to both. I defend a similar conclusion, but argue that the distinction between animal models and theoretical models does not always track a difference in the justification of model-to-target inferences. Case studies of the use of animal models in biomedicine are presented to illustrate this. However, Levy and Currie’s point can be argued for in a different way. I argue for the following distinction. Model organisms (and other concrete models) function as surrogate sources of evidence, from which results are transferred to their targets by empirical extrapolation. By contrast, theoretical modelling does not involve such an inductive step. Rather, theoretical models are used for drawing conclusions from what is already known or assumed about the target system. Codifying assumptions about the causal structure of the target in external representational media (e.g. equations, graphs) allows one to apply explicit inferential rules to reach conclusions that could not be reached with unaided cognition alone (cf. Kuorikoski and Ylikoski 2015).

Abstract:
Mounting observational data confirm that about 73% of the energy density consists of dark energy which is responsible for the current accelerated expansion of the Universe. We present observational evidences and dark energy projects. We then review various theoretical ideas that have been proposed to explain the origin of dark energy; they contain the cosmological constant, modified matter models, modified gravity models and the inhomogeneous model. The cosmological constant suffers from two major problems: one regarding fine-tuning and the other regarding coincidence. To solve them there arose modified matter models such as quintessence, k-essence, coupled dark energy and unified dark energy. We compare those models by presenting attractive aspects, new rising problems and possible solutions. Furthermore, we review modified gravity models that lead to late-time accelerated expansion without invoking a new form of dark energy; they contain f(R) gravity and the Dvali–Gabadadze–Porrati (DGP) model. We also discuss observational constraints on those models and on future modified gravity theories. Finally we review the inhomogeneous Lemaître–Tolman–Bondi (LTB) model that drops an assumption of the spatial homogeneity of the Universe. We also present basics of cosmology and scalar field theory, which are useful especially for students and novices to understand dark energy models.

Abstract:
Two-dimensional model calculations for inhomogeneous diffuse and translucent clouds are presented which include line and continuum radiative transfer, thermal balance and chemical equilibrium. The effects of an inhomogeous density distribution on the abundances of chemical species and line maps are discussed. Additional calculations are presented for the fluorescently pumped H2 visual and infrared lines which emanate from spherical diffuse clouds. The results indicate that these lines yield sensitive probes of the ambient cloud density when combined with co-spatial HI observations.
