Hydrophobicity of abiotic surfaces governs droplets deposition and evaporation patterns.

Surface contamination with droplets containing bacteria is of concern in the food industry and other environments where hygiene control is essential. Deposition patterns after the drying of contaminated droplets is affected by numerous parameters. The present study evaluated the rate of evaporation and the shape of deposition patterns after the drying of water droplets on a panel of materials with different surface properties (topography, hydrophobicity).

Effect of innovative microwave assisted freezing (MAF) on the quality attributes of apples and potatoes.

This study considered the effect of low energy microwave assisted freezing (MAF) on freezing time and quality attributes (microstructure, texture, drip loss and colour) of apple and potato. MAF of apples and potatoes was performed by applying constant microwave (MW) power (167 W/kg) and pulsed MW power (500 and 667 W/kg with 10 s pulse width and 20 s pulse interval resulting in an average power of 167 and 222 W/kg) during the freezing process. The temperature profile was monitored during the freezing process, and the microstructure was examined using X-ray micro-tomography and cryo-SEM.

Assessment of freeze damage in fruits and vegetables.

Freezing is an efficient and widely used method of food preservation. However, it can also cause irreversible damages at cellular level which in turn degrade the overall quality of the frozen food products. Therefore, qualitative and quantitative methods and technologies that will be able to evaluate with accuracy the freeze damage are of great importance.

First detection and identification of Candidatus Neoehrlichia mikurensis in South Korea.

Candidatus Neoehrlichia mikurensis (Ca. N. mikurensis; family Anaplasmataceae) is an emerging tick-borne pathogen that causes a systemic inflammatory syndrome with thrombotic complications.

Case Report: Polymerase Chain Reaction Testing of Tick Bite Site Samples for the Diagnosis of Human Granulocytic Anaplasmosis.

Human granulocytic anaplasmosis (HGA) is a tick-borne infectious disease caused by , an obligate intracellular bacterium. Until now, the utility of tick-bite site samples for HGA diagnosis has not been reported. Using a patient's buffy coat and tick-bite site crust samples, we performed polymerase chain reaction (PCR) testing using - or -specific primers.

Thermoluminescence properties of Eu-doped and Eu/Dy-codoped Sr Al SiO phosphors.

We report the thermoluminescence properties of Sr Al SiO :Eu and Sr Al SiO :Eu Dy phosphors. These phosphors were prepared by a high-temperature solid-state reaction method. The prepared phosphors were characterized by X-ray diffraction.

Synthesis, characterization and thermoluminescence studies of (ZnS) (MnTe) nanophosphors.

The present paper reports the thermoluminescence (TL) of (ZnS) (MnTe) nanophosphors that were prepared by a wet chemical synthesis method. The structure investigated by X-ray diffraction patterns confirms the formation of a sphalerite phase whose space group was found to be F 4¯3m. From XRD, TEM and SEM analyses the average sizes of the particles were found to be 12 nm, 11 nm and 15 nm, respectively.

Tenosynovitis caused by Scedosporium apiospermum infection misdiagnosed as an Alternaria species: a case report.

Background: Scedosporium apiospermum, which can usually be isolated from soil, polluted stream water and decaying vegetation, is increasingly recognized as an opportunistic dematiaceous fungus. The mortality rate of infection in immunocompromised hosts is over 50%. S.

Transmission of Enterobacter aerogenes septicemia in healthcare workers.

Enterobacter aerogenes is recognized as an important bacterial pathogen in hospital-acquired infections. This report describes two unusual cases of septicemia caused by E. aerogenes in immunocompetent healthcare workers.

Mechanoluminescence of SrAl O :Eu,Dy nanophosphors induced by low impact velocity.

The present paper reports the impulsive excitation of mechanoluminescence (ML) in Sr Al O :Eu ,Dy nanophosphors prepared using a combustion technique. The phosphors are characterized using X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and photoluminescence (PL). The XRD results show that the samples exhibit a monoclinic α-phase in the crystal structure.

Laser shock wave-induced visible mechanoluminescence from semi-transparent organic crystals.

Indirect focusing of the output from a pulsed infrared Nd :YAG laser through a shock-generating layer onto organic crystals results in the emission of an intense microsecond duration pulse of mechanoluminescence (ML). The ML appears after a threshold laser fluence has been reached and increases sharply above this threshold. This specifies that there is a corresponding amplitude of a laser-induced shock wave that is necessary to induce crystal fracturing.

Laser power dependence of mechanoluminescence in metals.

Mechanoluminescence (ML) glow is produced on the back side when the front of a metal sample is irradiated with infrared Nd:YAG laser pulses. An incident laser beam with a power density below the plasma-flare onset threshold causes a rise in temperature in the studied metal. As the incident laser power density increases, the intensity of the ML glow signal also increases.

Effect of UV irradiation on different types of luminescence of SrAl O :Eu,Dy phosphors.

This paper reports the luminescence behavior of Sr Al O :Eu ,Dy phosphors under UV-irradiation. The effect of UV-irradiation on afterglow (AG), thermoluminescence (TL) and mechanoluminescence (ML) of Sr Al O :Eu ,Dy phosphors is investigated. The space group of Sr Al O :Eu ,Dy phosphors is monoclinic P2 .

First report of iliacus abscess caused by Salmonella enterica serovar Othmarschen.

The non-typhoidal bacterium Salmonella enterica subspecies enterica serovar Othmarschen (Salmonella Othmarschen) is a rare human pathogen. Abscess formation due to non-typhoidal Salmonella infections is a very rare complication in this antibiotic era. We report the first case of iliacus abscess after a short period of gastroenteritis which was caused by non-typhoidal Salmonella enterica belonging to group C1, serovar Othmarschen in a patient without any underlying conditions.

Is the fracto-mechanoluminescence of ZnS:Mn phosphor dominated by charged dislocation mechanism or piezoelectrification mechanism?

Mathematical approaches made for both the charged dislocation model and piezoelectrically induced electron bombardment model of fracto-mechanoluminescence (FML), the luminescence induced by fracture of solids, in ZnS:Mn phosphor indicate that the piezoelectrically induced electron bombardment model provides a dominating process for the FML of ZnS phosphors. The concentration of 3000 ppm Mn(2+) is optimal for ML intensity of ZnS:Mn phosphor. The decay time of ML gives the relaxation time of the piston used to deform the sample and the time tm of maximum of ML is controlled by both the relaxation time of the piston and decay time of charges on the newly created surfaces of crystals.
