Multi-Pulsed High Hydrostatic Pressure Treatment of Foods

open access: yesFoods, 2015
Multi-pulsed high hydrostatic pressure (mpHHP) treatment of foods has been investigated for more than two decades. It was reported that the mpHHP treatment, with few exceptions, is more effective than the classical or single-pulsed HHP (spHHP) treatment ...

High Pressure Enhances the Growth Rate of the Thermophilic Archaebacterium Methanococcus thermolithotrophicus without Extending Its Temperature Range [PDF]

open access: yes, 1988
Temperature and hydrostatic pressure are essential in determining the assemblage of species in their specific biotopes. To evaluate the effect of high pressure on the range of viability of thermophiles, the pressure and temperature dependence of the ...

Accelerated degradation of polyetheretherketone and its composites in the deep sea [PDF]

open access: yesRoyal Society Open Science, 2018
The performance of polymer composites in seawater, under high hydrostatic pressure (typically few tens of MPa), for simulating exposures at great depths in seas and oceans, has been little studied.

Enhanced levels of cold shock proteins in Listeria monocytogenes LO28 upon exposure to low temperature and high hydrostatic pressure [PDF]

open access: yes, 2002
Listeria monocytogenes is a psychrotrophic food-borne pathogen that is problematic for the food industry because of its ubiquitous distribution in nature and its ability to grow at low temperatures and in the presence of high salt concentrations.

In-Situ Synchrotron Profile Analysis after High-Pressure Torsion Deformation

open access: yesCrystals, 2019
The presence of hydrostatic pressure is a general crucial characteristic of severe plastic deformation methods for reaching high strains and for introducing large quantities of lattice defects, which are necessary to establish new grain boundaries ...

The influence of hydrostatic pressure on the interlaminar fracture toughness of carbon/epoxy composites [PDF]

open access: yes, 2006
The use of composites for deep sea applications requires a thorough understanding of the behaviour of these materials. While several studies have examined the influence of pressure on in-plane properties few data are available for the interlaminar ...

Effect of non-hydrostatic stress on the structure and elasticity of NaCl by first-principles calculation

open access: yesAIP Advances, 2019
Non-hydrostatic stresses have a unique influence on materials. To understand the effect of non-hydrostatic stress on NaCl, one of the most widely used pressure calibrant in high-pressure experiments, the lattice constants, density, elastic modulus, Young’

Establishing safe high hydrostatic pressure devitalization thresholds for autologous head and neck cancer vaccination and reconstruction

open access: yesCell Death Discovery, 2023
High hydrostatic pressure specifically devitalizes cells and tissues without major changes in their molecular structure. Hence, high hydrostatic pressure may enhance the development of whole-cell anti-tumor vaccines, representing tumor heterogeneity and ...

Design of a Hydrostatic Spindle and Its Simulation Analysis with the Application to a High Precision Internal Grinding Machine

open access: yesMachines, 2022
Hydrostatic thrust bearings are the core part of the hydrostatic spindle, which is widely used in high precision grinding machines. In this paper, the viscosity-temperature (v-t) characteristics of hydrostatic oil are systematically investigated, which ...
