A significant part of all types measurements performed in modern industry and science are gas, liquid or other media. This is important because there many processes where you need to clearly control the parameters environment - pressure, density, etc. The object research MEMS gas density sensors. subject eliminate shortcomings existing similar systems, increase accuracy measurement range measur...

BACKGROUND Inadequate parenting is an important public health problem with possible severe and long-term consequences related to child development. We have solid theoretical and political arguments in favor of efforts enhancing the quality of the early family environment in the population at large. However, little is known about effect of universal approaches to parenting support during the tra...

A hybrid multiscale mathematical model of tumor growth is used to investigate how tumoral and microenvironmental heterogeneity affect the response of the immune system. The model includes vascular dynamics and evolution of metabolic tumor phenotypes. Cytotoxic T cells are simulated, and their effect on tumor growth is shown to be dependent on the structure of the microenvironment and the distri...

Tumors are typically heterogeneous tissues comprised of multiple cell species in addition to extra-cellular matrix (ECM) and water fluid. It is difficult to model these components at the tissue (10–10m) scale, where individual cells cannot be represented without prohibitive computational burden. Assuming that same-kind components tend to cluster together, a multiphase approach can be applied to...

This paper reports a modelling work on the existing experimental data of single coal particles combustion process [1,2]. Two kinds of coal particles (a high-volatile bituminous coal / a lignite coal) are injected in a drop-tube furnace, ignited and burned in quiescent O2/N2 and O2/CO2 atmospheres with oxygen mole fraction varying from 20% to 100%. Ignition delay time, particle life time and par...

Across the nation, numerous legacy electronics technology programs at the two-year college level are: being converted to Cisco and A+ based computer networking and repair programs, increasingly being asked to teach electronics fundamentals to non-electronics based technologies, and, most significantly, experiencing declining enrollments. In some cases, programs have been discontinued entirely d...

This paper discusses the financial and technical principles underlying the levelized cost (LC) method of computing the cost of storing photovoltaic (PV) electricity (LCOS). The paper presents a CL algorithm. The algorithm equations are presented. The algorithm uses nine recognized energy storage system (ESS) specifications (specs) to compute the levelized cost of the stored PV electricity. Publ...
