AimsHigh-mobility group box 1 protein (HMGB1) is one of the recently defined damage-associated molecular pattern molecules derived from necrotic cells and activated macrophages. We investigated clinical implications serum HMGB1 elevation in patients with acute myocardial infarction (MI). Then, we evaluated effect blockade on post-MI left ventricular (LV) remodelling a rat MI model.
Large-scale micromagnetic simulations have been performed using the energy minimization method on a model with structural features similar to those of Dy grain boundary diffusion (GBD)-processed sintered magnets. Coercivity increases as linear function anisotropy field Dy-rich shell, which is independent composition in core long shell thickness greater than about 15 nm. This result shows that contained initial magnets prior GBD process not essential for enhancing coercivity. Magnetization...
A group of Japanese subjects were phenotyped for CYP2D6 activity by administration sparteine and determination urine metabolic ratios (MR). The alleles from two having a high MR, characteristic slower rates metabolism, cloned in λEMBL3 subjected to sequence analysis. One individual possessed CYP2D6B allele, typically found Caucasians, that is inactive due an altered 3' splice recognition site other potentially disruptive mutations. second allele this was identical the wild type normal...
The effects of moisture on the initial and long-term bonding behavior fiber reinforced polymer (FRP) sheets to concrete interfaces have been investigated by means a two-year experimental exposure program. research is focused (1) at time FRP installation, in this paper termed “construction moisture,” consisting substratum surface external air moisture; (2) moisture, “service which normally varies throughout service life concrete. Concrete beams with bonded their soffits were prepared. Before...
Transmission characteristics and reliability for pure-silica-core single-mode fiber with matched cladding are presented. On account of the "pure" silica core, without any additives, features low attenuation improved chemical stability under existence hydrogen γ-ray radiation. High mechanical good splicing behavior fibers were also confirmed. More than 2000 km have been fabricated, exhibiting median 0.35 dB/km at 1.3 μm 0.21 dB/ 1.55 μm. The achieved minimum was 0.154 <tex...
Bridge censored databases can be used to analyze and assess structural deterioration conditions, but conducting the analysis is difficult. This difficulty occurs because many factors affect deterioration, time span of data for these depends on years in service respective bridge. In addition, values some are not regularly observed. The present study uses long short-term memory (LSTM) consider twelve potentially influencing recognize relationships between grades. Testing model an inspection...
Waste fishing nets were utilized as recycled nylon (RN) short fiber to improve the mechanical properties of cement mortar. RN and manufactured polyethylene (PE) fibers added polymer mortar (PCM) a reinforcement, fiber-reinforced PCM was sprayed on section reinforced concrete (RC) beams. Normal RC beams upgraded placed in tidal zone for 14 months induce rebar corrosion. Consequently, repair operation took place by removal cover then spraying PCM. The tested subjected four-point flexural tests...
In this paper we propose a rapid and highly selective far-ultraviolet (FUV) spectroscopic method for the simultaneous determination of peracetic acid (PAA), hydrogen peroxide, acetic (AA). For purpose developed novel FUV spectrometer that enables us to measure spectra down 180 nm. Direct PAA, H2O2, AA, three main species in disinfectant solutions, was carried out by using their absorption bands 180−220-nm region. The proposed does not require any reagents or catalysts, calibration standard,...
Abstract Thin films of the superconductor YBa2Cu3O7−δ (YBCO) were prepared on yttria stabilized zirconia (YSZ) substrates by dipping-pyrolysis process. The starting solution, produced dissolving barium and copper naphthenates yttrium stearate into an organic solvent, was coated heated up to 800 °C. Resistivities measured four probe method superconduction observed at Tc = 90 K (onset) 60 (end).
One of the important factors for compressive stress-strain curves concrete is localization failure. The curve strongly depends on aspect ratio specimen; therefore, a unique not adequate to express softening behavior concrete. To overcome problem related failure, series uniaxial tests specimens was conducted. From measured energy distribution, failed specimen assumed be composed 2 or 3 zones. Then, an equation envelope involving characteristic strength formulated so as match experimental each...
A new type of polarisation-maintaining fibre is proposed, analysed, and preliminary fabrication measurement are described. The features two 'side tunnels' bored on both sides the core, exhibits an absolutely single-polarisation characteristic or a relatively strong modal birefringence. normalised birefringence obtained so far 0.73×10−4. This value appreciably lower than expected. Two possible reasons discussed.
The arsenic contamination of groundwater in Uttar Pradesh State was first recognized 2003 and is now seen at 20 Districts out 70 Districts. University Miyazaki has performed the mitigation project Bahraich District, severest arsenic-affected one Districts, from June 2008 until now, with JICA (Japan International Cooperation Agency). integrated mitigation, such as raising awareness villager, installing alternative water supply units healthcare arsenocosis patients, have been executed 2...
