To evaluate the food safety effect of NaCl-free processing, acidification, smoking and high pressure in QDS processed dry-cured ham, 3 ham types (non-acidified smoked, acidified, and acidified smoked) were produced according to a standard (-S) and a new NaCl-free (-F) process. Slices were spiked with Listeria monocytogenes and Salmonella enterica (three strains each, <2 log CFU/g), dried by the...

High hydrostatic pressure (HHP) has been investigated and industrially applied to extend shelf life of meat-based products. Traditional ham packaged under microaerophilic conditions may sometimes present high lactic acid bacteria population during refrigerated storage, which limits shelf life due to development of unpleasant odor and greenish and sticky appearance. This study aimed at evaluatin...

Evidence from light microscopy (principally polarization microscopy) has demonstrated that hydrostatic pressure can reversibly inhibit mitosis by rapidly depolymerizing the spindle fiber microtubules. We have confirmed this finding in ultrastructural studies of mitotic HeLa cells incubated at 37 degrees C and pressurized at 680 atm (10,000 psi). Althouth there are many spindle microtubules in t...

Pressurized hot water extraction (PHWE) has become a popular green extraction method for different classes of compounds present in numerous kinds of matrices such as environmental, food and botanical samples. PHWE is also used in sample preparation to extract organic contaminants from foodstuff for food safety analysis and soils/sediments for environmental monitoring purposes. The main paramete...

In this paper we present the developments in heat flux measurements using gradient sensors (GHFS). The GHFS is a sensor made of artificially created material with anisotropic thermo-electrical properties. Its properties including small size, robustness and low response time make it valuable addition for characterizing space-limited geometries as well harsh environmental conditions. This makes i...

The work presented in this paper deals with bias and uncertainty quantification on nuclear fuel inventory a pressurized water reactors core during normal operation. This actinides fission products is used as input data for radiological releases evaluation case of severe accident. different sources uncertainty, well their impacts UO 2 MOX at the assembly levels, are discussed. Uncertainty includ...

High altitude seemed to be responsible for seven recent cases of sickling crisis. People with sickle-cell trait are at risk if they fly in unpressurized aircraft, which are used for many local air services. Those with sickle-cell haemoglobin C disease should avoid air travel even in pressurized aircraft. Possibly as a result of "autosplenectomy," patients with sickle-cell anaemia seem to be abl...

One promising way of facing recent challenges to slow down the climate crisis or reduce dependencies on fossil energy sources, e.g. natural gas, is using renewable methane and other e-fuels for storage distribution via existing infrastructure. Solid oxide cell (SOC) reactors play an important role in conversion sustainable electric power into chemicals as they can be obtained from combined stea...
