Both the pineal hormone melatonin (Mel) and postural changes have thermoregulatory sequelae. The purpose of the study was to evaluate their relationship to subjective sleepiness. Eight healthy young men were investigated under the unmasking conditions of a constant routine protocol. Heart rate, rectal temperature (Tre), skin temperatures (foot, Tfo; and stomach), and subjective sleepiness ratin...

Productions, mechanical and microstructural analyses of bioglass/sheep hydroxyapatite (SHA) composites are introduced. Bioglass were added to calcinated SHA with various concentrations 5 and 10 wt. %. Powder mixture compacted with pressure (350 MPa) in steel moulds to obtain cylinder samples. As the next step, samples sintered in air at various temperatures (1000, 1100, 1200, 1300 C for 4 hrs)....

Hydroxylated polychlorinated biphenyls (OH-PCBs) are formed as major metabolites of PCBs by cytochrome P450 enzyme-mediated oxidation. It has been reported that their total concentration in serum samples of Yusho patients ranged from 390 to 1300 pg/g. We measured the concentration of OH-PCBs in blood collected from 183 Yusho patients living in Japan in 2010. The major OH-PCB metabolites were 4-...

We proposed a design for a LASER pico-projector with a low speckle contrast value and high contrast ratio that maintains system efficiency. The method for speckle contrast reduction utilizes two diffusers and a Voice Coil Motor (VCM) oscillator. The two different diffusers for a high contrast ratio and high system efficiency can be divided into two categories. In Category 1, the speckle contras...

[1] An analysis of a sudden commencement (SC) manifestation reveals a significant contribution of the polar current system which influences the long-term behavior of the H component at low-latitude ground stations located in the subsolar sector. A transition between ‘‘morning’’ and ‘‘afternoon’’ characteristics of the geomagnetic response occurs at 1300 MLT. ‘‘Morning’’ events are characterized...

The reaction pathway for the Ca3Al2O6 formation up to 1300 C; from mechanochemically treated mixtures of amorphous aluminum hydroxide and CaCO3; was studied in situ by differential thermal analysis, constant heating rate dilatometry and timeresolved neutron powder diffraction. The experiment was carried out, in an open system, on a sample with the nominal Ca3Al2O6 stoichiometry. The results obt...

Carbon layers doped with Ti, V, W, and Zr to about 15 at.% were produced by means of magnetron sputter deposition, which distributes metal atoms homogeneously in the amorphous carbon matrix. The effects of thermal annealing to temperatures of 500–1300 K on the phase, crystallinity and distribution of the dopant were determined. X-ray diffraction (XRD), MeV ion beam analysis (IBA), and extended ...

The available data on the a0(980), f0(980), f0(1300) and K 0 (1430) mesons are fitted as a distorted 0 qq̄ nonet using only 6 parameters and a very general model. This includes all light two-pseudoscalar thresholds, constraints from Adler zeroes, flavour symmetric couplings, unitarity and physically acceptable analyticity. One finds that with the large overall coupling there can appear two physi...

We demonstrate multiphoton NDD FLIM of tissue samples stained with near-infrared dyes. For the experiments we used a Zeiss LSM 7MP multiphoton microscope with a Coherent Chameleon OPO (optical parametric oscillator) as an excitation source. The excitation wavelengths range from 1000 nm to 1300 nm. The fluorescence was detected by an HPM-100-50 NIR hybrid detector attached to the NDD (non-descan...

The thermochemical degradation of hafnium silicate (HfSiO4) was investigated with a molten calcium-magnesium-aluminosilicate (CMAS) glass relevant to gas turbine engine applications. Sintered HfSiO4 coupons were fabricated, within which wells drilled and filled CMAS powder at loading ∼35 mg/cm2. Samples heat treated 1200°C, 1300°C, 1400°C, 1500°C for 1 h, 10 50 h. At 1200°C slow formation Ca2Hf...
