Abstract:
The studies are dedicated to some changes into the mathematical model and improvement of the algorithm of converting watmetrograms into dynamograms in the horsehead. The paper researches the kinematics of the horsehead. The mathematical model is developed considering the mass of the sucker rod pump.

Abstract:
Context. Micro-physical processes on interstellar dust surfaces are tightly connected to dust properties (i.e. dust composition, size, and shape) and play a key role in numerous phenomena in the interstellar medium (ISM). The large disparity in physical conditions (i.e. density and gas temperature) in the ISM triggers an evolution of dust properties. The analysis of how dust evolves with the physical conditions is a stepping stone towards a more thorough understanding of interstellar dust. Aims. We highlight dust evolution in the Horsehead nebula photon-dominated region. Methods. We used Spitz

Abstract:
Context. The large disparity in physical conditions from the diffuse interstellar medium (ISM) to denser clouds such as photon-dominated regions (PDRs) triggers an evolution of the dust properties (i.e. composition, size, and shape). The gas physics and chemistry are tightly connected to these dust properties and are therefore affected by dust evolution and especially the nano-grain depletion in the outer irradiated part of PDRs. Aims. We highlight the influence of nano-grain depletion on the gas physics and chemistry in the Horsehead nebula, a prototypical PDR. Methods. We used a model for at

However, there is little research on the influence of beam pumping unit under wind load. Based on the dynamics of solid-fluid interaction theory and the standard k- turbulence model, this paper calculated the polished rod load range of the pumping unit according to the actual working co

Abstract:
The paper gives brief literature review on the specification of maximum load acting on the horsehead. Additionally, it presents a new method of specification of the friction force acting via ""Quantor-4micro"" hardware-software complex, with the dynamometer of which the dynagraph is taken. The maximum load, which is equal to the sum of all forces acting on the horsehead is graphically specified through the upper horizontal straight dynagraph. The friction force called unknown value is involved among them as well. The equation is developed and friction force value specified.

Abstract:
We have made a preliminary map of the Horsehead nebula in CO (J=1-0) using the NRO 45-m telescope. The HPBW is 15″, the grid spacing 10″, and the velocity resolution is ∼0.1km/s. Figure 1 shows the integrated intensity with a velocity interval 10-11.5 km/s, which we found represents well the shape of the dark globule of the Horsehead. The coincidence of the CO feature and the dark nebulocity is strikingly well, especially at the sharp edges in the south and in the west (from the neck to the ears). The quality of the data are not satisfactory, though. The typical noise level is 1 K rms in TA, a
