Abstract:

The temperature dependence of the viscosity of inorganic glasses in the glass transition region is successfully described by the Williams--Landel--Ferry (WLF) equation. For the studied glasses, the value of f_g=1/C1 weakly depends on the nature of the glasses. There is a linear correlation between delta delta Tg and Tg. From the data on the parameters of the WLF equation C1 and C2, we calculated delta delta Tg, as well as the relaxation time of the structure taug at the glass transition temperature of the glasses under study. Keywords: Viscosity in the glass transition region, Williams--Landel

Abstract:

The work presented in this paper is part of a wider research project, which aims at documenting and analyzing stained glass windows by means of hyperspectral imaging. This technique shares some similarities with UV-VIS-IR spectroscopy, as they both provide spectral information; however, spectral imaging has the additional advantage of providing spatial information, since a spectrum can be collected in each pixel of the image. Compared to UV-VIS-IR spectroscopy, spectral imaging has rarely been used for the investigation of stained glass windows. One of the objectives of this paper is, thus, to

However, in this circumstance, the estimated effect size and associated standard errors will need to be pooled and estimated from the imputed dataset.

The Sheep Creek tephra (ca. 190,000 yr) is reworked in alluvium of Delta age. The upper and lower limiting tephra dates indicate that the Delta glaciation occurred during marine oxygen isotope stage 6.

Tan Delta reflects the viscoelastic behavior of materials, particularly polymers.

However, achieving a high Tan Delta over a broad temperature range is challenging, particularly for engineering applications that involve significant temperature fluctuations.

The objective of this work was to evaluate peroxidase activity and protein concentration in the defence system expression of common bean Phaseolus vulgaris L., submitted to different potencies of homeopathic preparations. The treatments were composed by: Arsenicum album, Staphisagria, Silicea and Sulphur, in the 6, 12 and 18 CH potencies, compared to the controls. The bean seeds were sown in pots which were kept in a greenhouse and the treatments were applied to them at 1% in distilled water since the sowing day, with intervals of 15 days until the R7 stage. The first evaluation was performed

Abstract:

The topographic relationship between previously identified medullary ventral surface respiratory chemosensitive regions and brain surface extracellular fluid (ECF) acid production during acute hypoxia was explored in anesthetized, paralyzed, and artificially ventilated cats. Glass pH electrodes (0.8-mm diam, sheathed in stainless steel tubing) were mounted in mechanical contact with surfaces of medullary surface or adjacent pyramids, pons, spinal cord, or parietal cortex. Isocapnic hypoxia of 5 min [at arterial O2 saturation (SaO2) = 48 +/- 10%] reduced pH over rostral (Mitchell) and caudal (L

Abstract:

The influence of the surface pH (pHs) on the intracellular pH (pHi) and the recovery of pHi after an imposed intracellular acid load was investigated in isolated sheep cardiac Purkinje fiber, rabbit papillary muscle, and mouse and rat soleus muscle. pHs and pHi, respectively, were continuously measured by use of single- and double-barreled pH-sensitive glass microelectrodes. Surface acidosis, usually obtained by superfusion with solutions of acid pH, was also produced with low buffered (5 mM N-2-hydroxyethylpiperazine-N'-2-ethane-sulfonic acid) solutions at control pH.

Abstract:

In general, composite materials are widely used in many industries. A composite material is a material composed of two or more components. Such a composite material differs in its properties from the individual components of the entire composite. This contribution is aimed at evaluating the parameters of selected composite materials - wood fiber boards, carbon prepreg boards and epoxy boards. The measured quantities that were investigated on the given materials were the modulus of elasticity, the loss modulus and the tan delta angle. To evaluate the properties of the given composite materials,

Abstract:

Due to their complexity, detecting and analysing damage modes in composite honeycomb sandwich panels can be difficult. This article describes the way in which a three-point bending test (3PBT) was performed on a glass fibre aluminium honeycomb sandwich panel (HSP). Acoustic emission (AE) was used to identify damage signals, which were then analysed to determine the positions and characteristics of defects. To locate damage positions, Delta-T mapping was used. The test load was progressively applied in three phases, with the specimen being inspected visually during each phase. A scanning electr

The dynamic mechanical properties of radial and chordwise bamboo pieces were tested by dynamic mechanical analysis (DMA). The results show that the storage modulus and loss modulus and tangent delta of chordwise direction were all larger than the radial direction of bamboo; the peak of glass transition temperature of chordwise direction is high than the radial direction, and their sizes are very close; dynamic mechanical analysis can provide a reference for the optimization applicable environment temperature of curtain plybamboo.
