One of the main data collection methods for large-scale agricultural mapping is remote 112 sensing. Remote sensing images, especially with high spatial resolution, obtained from various satellite systems, provide detailed, reliable and accurate information about agricultural land. Satellite images are subject to distortion under the influence of various factors, many of which are corrected during preprocessing. However, images that have undergone only preliminary processing cannot always meet the requirements for compiling large-scale maps and plans. To do this, it is necessary to geometric correction or rectification satellite images using additional data, rational polynomial coefficients (RPC) and coordinates of ground control points. This article is devoted to the issues of rectification of satellite image with high spatial resolution Kompsat 3A by the method of polynomials of rational functions and estimation its accuracy

    Experimental Study of the Effect of Composite Solvent and Asphaltenes Contents on Efficiency of Heavy Oil Recovery Processes at Injection of Light Hydrocarbons

    The current state of research in the field of solvent injection techniques for increase of heavy oil production efficiency is discussed in the chapter. As a result of a series of experiments on the physical modeling of oil displacement processes in a porous medium in large-sized model, features of asphaltene precipitation and the formation of fixed residual oil upon injection of solvent based on light alkanes are revealed. The oil displacement by n-hexane was studied and the difference in the composition of residual oil in the zones of dispersion and diffusion has been shown. The influence of the composition of asphaltenes peculiarities on the dynamics of oil recovery and on the accumulated oil recovery during the injection of n-hexane, as well as the composition and quantity of asphaltenes precipitated in the porous medium, has been estimated. The effect of toluene and nonylphenol additives on the proportion of asphaltenes in the residual oil and cumulative oil recovery has been evaluated using the Ashalchinskoye field oil as an example of heavy oil in the physical modeling of injection of n-hexane as the base solvent

    Tribology of particle suspensions in rolling-sliding soft contacts

    Get PDF
    We investigate the lubrication of microsphere suspensions between compliant substrates, and probe the influence of matrix viscosity, particle phase volume, surface roughness and wetting, and slide-to-roll ratio (SRR). In general, the suspensions behave as a continuum in the elastohydrodynamic regime provided the film thickness, which is predicted from the product of speed and viscosity, is greater than the particle diameter. Below this, the frictional response is characteristic of the mixed and boundary regimes. In the boundary regime, friction is independent of phase volume above 5% and it is governed by the rolling friction associated with particles being entrained into the contact that is independent of SRR, which is made possible by substrate deformation. This study provides a benchmark for soft-tribology and biotribology studies involving more complex particle suspensions and particle-containing soft materials

    Fetal Pig Dissection Manual (BIOL 105)

    Get PDF
    This book is a guide to the basic fetal pig dissection conducted as a part of the Queens College, CUNY Biology Department Bio105 General Biology: Physiology and Cell Biology course. This course is the first half our two-part series for biology majors. The actives are designed to be conducted over a three- 3-hour lab periods which focus on the relationship of form and function of the pig anatomy and physiology. Step by step instructions for the dissection are provided along with some microscopy tasks to look at the histology of key organs. In addition to the full text of the book, we also provide a form with just the assessment portions of the book. This allows students to limit the printed material to just those pages

    Electron Clusters in Inert Gases

    Full text link
    The paper addresses counterintuitive behavior of electrons injected into dense cryogenic media with negative scattering length a0a_0. Instead of expected polaronic effect (formation of density enhancement clusters) which should substantially reduce the electron mobility, an opposite picture is observed: with increasing ∣a0∣|a_0| (the trend taking place for inert gases with the growth of atomic number) and the medium density, the electrons remain practically free. An explanation of this behaviour is provided based on consistent accounting for the non-linearity of electron interaction with the gaseous medium in the gas atom number density

    This book is a guide to the basic histology lab conducted as a part of the Queens College, CUNY Biology Department Bio105 General Biology: Physiology and Cell Biology course. This course is the first half our two-part series for biology majors. The actives are designed to be conducted over a single 3-hour lab periods which focus on the relationship of form and function of the cellular and organ level anatomy and physiology. Step by step instructions for each slide set are provided for all the key organs. In addition to the full text of the book, we also provide a checklist form with just the assessment portions of the book. This is to help summarize all the information the student should get from the activity
