2020-6-2 Your blood pressure depends on pumping organ – the heart. Blood is pumped from the heart to other parts of the body by vessels. As per WHO (world health organisation) report – around 1.13 billion people have hypertension worldwide. Today we will understand the mechanism of high blood pressure. There are several physiological mechanisms which regulate blood pressure

2019-3-1 The high pressure inhibits the isomerization of QC into NBD and the retro-Diels-Alder reaction of NBD, but promotes the isomerization reactions of NBD into CHT and into TOL. The further reactions of CPD and TOL produce small molecules and aromatic products, mainly from the combination between CPD and cyclopentadienyl (CPDyl).

2012-10-1 High pressure (HP) has been showed to induce coagulation of proteins without drastic chemical changes as observed with heat treatment which can result in destruction of covalent bonds. However, higher pressures have been found to increase the lightness (L*) and reduce redness (a*) comparing to raw meat (Carballo et al., 2000, Carlez et al., 1993).

2017-1-1 Having established the general validity of the previous analysis allows the formulation of a conceptual model for turbulent ignition in high-pressure spray flames. Figure 8 presents the evolution of this mechanism which is associated with a set of characteristic time scales. (1) Localized first-stage ignition occurs in the lean-limit of the mixture since it generally exhibits the highest temperature in the

Abstract Quadricyclane (QC), a kind of strained and caged hydrocarbon, is a potential green high energy density liquid fuel. The pyrolysis experiments of QC (473–1073 K, and 1.0–2.0 MPa) were conducted in a micro-reactor equipped with online GC–MS/FID to understand its high pressure mechanism. It is found that QC firstly isomerizes into 2,5-norbornadiene (NBD) before 598 K under 1.0 MPa ...

2020-10-6 High pressure equipment comprises of pressure vessel and its closure, PTM, two or more pumps to generate pressure and temperature controller. Pressure vessel is the heart of HPP equipment, which is mostly forged monolithic cylindrical vessel and can be operated at the pressure in the range of 400–600 MPa depending on the internal diameter of vessel.

2019-2-5 The high-pressure phase diagrams of binary Se–N system have been constructed using the CALYPSO method and first-principles calculations. Four stable compounds (Cmc21-SeN2, P21/m-SeN3, P1̅-SeN4, and P1̅-SeN5) were identified at high pressures. Various peculiar nitrogen polymerization forms composed of single/double nitrogen–nitrogen bonds were found at the nitrogen-rich condition, such as ...

Deep gas wells and gas fields have the characteristics of high pressure. The vibration of the tubing string during the production of gas wells causes the string to be subjected to severe stress and even dynamic fatigue failure. Therefore, this article is based on the dynamic finite element theory, aiming at the characteristics of large-size tubing strings in deep gas wells.

Abstract High pressure and high temperature reactions in the system BN Mg 3 N 2 were examined to investigate the formation mechanism of cubic boron nitride. An unidentified phase (X-phase) was obtained in the composition between Mg 3 BN 3 and Mg 3 N 2 . The X-phase reacts with BN to form Mg 3 BN 3 at high pressure. We found no evidence of the decomposition reaction of the X-phase to form
