Common practice methods of tank design for transportation liquefied natural gas don’t take into account the specifics carriers operation under condition partial filling cryogenic tanks. A new method designing type-C is proposed. Method based on solving problem increasing volume transported by small-scale inland carriers. The usage a number limiting parameters: minimal allowable ventless time, v...

Let S be a set of n points in Rd in general position. A set H of k-flats is called an mk-stabber of S if the relative interior of any m-simplex with vertices in S is intersected by at least one element of H. In this paper we give lower and upper bounds on the size of minimum mk-stabbers of point sets in Rd and in general position. We study mainly mk-stabbers in the plane and in R3.

In this paper, the thermal performance of four common insulators in two internal and external insulation systems is investigated for the ASHRAE setpoint range by applying detailed numerical simulation and Anti-Insulation phenomenon. Anti-Insulation phenomenon and consequent extra load on the HVAC system can occur following the thermal insulation of a building if proper temperature setpoint is n...

Insulation of thermal energy storage tanks is fundamental to reduce heat losses and achieve high efficiency. Although water were extensively studied in the literature, enhancement insulation quality often overlooked. The use vacuum has potential significantly without affecting dimension system. This paper shows for first time results tests done a 0.535 m3 tank residential building applications ...

Because environmentally-friendly fuels such as natural gas and hydrogen are primarily stored in the form of cryogenic liquids to enable efficient transportation, demand for fuel (LNG, LH) ships has been increasing primary carriers fuels. In ships, insulation systems must be used prevent heat inflow tank suppress generation boil-off (BOG). The presence BOG can lead an increased internal pressure...

Electrical cables are a potential source of ignition and fire hazards in various types buildings industrial installations, as well all modes transportation, including aircraft. Fires pose the greatest threat to human life health. The composition thermal degradation products depends mainly on type combustible materials combustion process—flaming or smoldering. purpose this paper was determine, b...

PVC-441 murine leukemia virus (MuLV) is a member of the PVC group of Friend MuLV (F-MuLV)-derived neuropathogenic retroviruses. In order to determine the molecular basis for the difference in neuropathogenicity between PVC-441 and the previously characterized PVC-211 MuLVs, the entire nucleotide sequence of PVC-441 MuLV was determined and compared with those of PVC-211 and F-MuLV. The results s...
