Streszczenie:

The modelling of uncoupled fluid flow and heat transfer problems of a district heating network using the finite element method (FEM) is presented. Since the standard thermo-hydraulic pipe elements cannot be directly used for modelling insulation, the main attention was paid to discretisation of multilayered structure of pipes and surrounding by one-dimensional thermal elements. In addition, validity of the finite element method was verified numerically by solving fluid flow and heat transfer problems in district heating pipelines. Verification analysis involves standard single pipe problems an

Abstract Introduction/Objective The aims of our study were to optimize the workflow of non-small cell carcinoma (NSCC) endobronchial ultrasound-guided bronchoscopy with transbronchial needle aspiration (EBUS-TBNA) samples to maximize tissue available for next-generation sequencing (NGS), preserve formalin-fixed paraffin-embedded (FFPE) cell blocks (CBs) for future testing, and shorten turnaround time (TAT) of NGS results. We evaluated the performance of supernatant fluid (SNF) processed from a dedicated aspirate for NGS testing. Methods/Case Report 20 EBUS-TBNA samples positive for NSCC on rap

Abstract The eastern part of the “Seuil du Poitou” area had been selected by the French National radioactive waste management agency (ANDRA) as a potential site for building an underground laboratory in granitic rocks. 17 cored bore holes, completed by petrographical, geochemical [Cuney et al., 2001], geophysical [Virlogeux et al., 1999] and structural [Gros and Genter, 1999] studies, have provided a detailed knowledge of the Charroux-Civray complex, hidden under a Jurassic sedimentary cover. Three main types of magmas were distinguished : medium-K calk-alkaline, high-K calk-alkaline and peral

Presently the on-the-road transportation sector is responsible of the 21% of the whole CO2 amount emitted into atmosphere. This pushes the International Governments and Organizations to provide strict limitations in terms of ICEs emissions, also introducing fees payment for the car manufacturers. The vehicle electrification allows certainly to meet these requirements, but the higher cost and the need of a green electricity still limit a widespread diffusion among all social classes. Thus, the technological improvement of internal combustion engine plays a key role in the transition period. Amo

BackgroundTofacitinib is a potent and selective oral inhibitor prevalently of JAK1 and JAK3and is currently included in the international recommendations for the management of psoriatic arthritis (PsA). Nonetheless, the mechanisms of the immune response to the treatment remain unclear, particularly regarding the effects on overlooked immune cell subpopulations specifically involved in the pathogenesis of PsA, i.e. mucosal-associated invariant T cells (MAIT), innate lymphoid cells (ILCs), both relevant sources of IL-17, and T lymphocytes producing interleukin 9 (Th9).

Thermal management of the new generation’s high performance electronic and mechanical devices is becoming important due to their miniaturization. Conventionally, the plate fin arrangement is widely used for removal of dissipated heat but, their effectiveness is not up to mark. Among different options, the most attractive and efficient alternative for overcoming this problem is micro pin fin heat sink. This paper presents the experimental investigation of square micro-pin fins heat sink for identifying the most suitable pin fin geometry for heat removal applications under forced convection. Twe

A microchannel heat exchanger effectively evacuates heat from a confined space. This paper attempts to gain insight into the combinatorial repercussions of simultaneously coupling two factors that affect a microchannel’s performance, of which channel size and micro-insert complexity are the two main contributors. With water as the working fluid, an ANSYS-based numerical analysis was carried out for two distinct channel sizes, 1 and 2 mm, both with and without micro-inserts. The Reynolds numbers varied between 125 and 4992 and between 250 and 9985 for the 1 and 2 mm channels, respectively. For

Proton Exchange Membrane Fuel Cell (PEMFC) generates electricity through the reaction of hydrogen and oxygen. PEMFC is considered clean technology since the by-products of the reaction are only electricity, water, and heat. Thermal management of PEMFC can be further improved through the adoption of nanofluids as its cooling medium. Nanofluids are fluids that contain suspensions of nanoparticles in their base fluid. Nanofluids have better heat transfer performance as compared to their base fluid due to their significant thermal conductivity improvement. However, unlike any other heat transfer a

Abstract Background FVIIIa acts as a cofactor in the intrinsic pathway in which FIXa activates FX. ACE910 is a FIXa/FX-recognizing bispecific antibody that was designed to be a replacement for FVIIIa. Because of its nature, ACE910 is not affected by FVIII inhibitor. A clinical trial is now being conducted for the potential effect in the prophylactic treatment for bleeding hemophilia A patients. Here we present the perioperative care of a patient who had incidentally suffered from appendicitis and underwent an emergency surgery during the clinical trial.

ABSTRACT: The widely-used plastics, especially low-density polyethylene (LDPE), have resulted in a considerable accumulation of plastics in the waste stream, causing a global environmental problem. Therefore, the research aims to examine the thermal and catalytic degradation of waste LDPE plastic using spent fluid catalytic cracking (FCC) catalyst and compare the properties of the produced liquid oils with commercial fuels. The potential of converting the most energy from waste plastics to valuable liquid oil, gaseous, and char was investigated. A batch reactor was used to thermally and cataly

For reducing the initial GSHP investment, the heat transfer efficiency of the borehole heat exchange (BHE) system can be enhanced to reduce the number or depth of drilling. This paper proposes a novel and simple BHE design by changing the cross-sectional shape of the U-tube to increase the heat transfer efficiency of BHEs. Specifically, in this study, we (1) verified the reliability of the three-dimensional numerical model based on the thermal response test (TRT) and (2) compared the inlet and outlet temperatures of the different U-tubes at 48 h under the premise of constant leg distance and f
