Non conventional fracture tests of heterogeneous and anisotropicpaperboard composites
Non-conventional experimental procedures have been designed in order to characterize the overall \nconstitutive properties and to follow the evolution of the damaging phenomena leading to fracture of \nheterogeneous and anisotropic paperboard composites. Specimens are monitored all along the tests, either by \ndigital…
新型双β-二酮、邻菲罗啉和铕(III)三元配合物的合成与发光
A new ternary complex of Eu(superscript 3+) with bis(β-diketone) ligand 1, 3-bis[3-(2-thiophenyl)-3-oxopropan-oyl]benzene and 1, 10-phenanthroline was synthesized. The properties of this complex were characterized by IR, UV-Visible spectrometry, elemental analysis and TG-DSC. The photoluminescence of complex indicated…
Measurement of plasma parameters in Ar/O2 magnetron sputtering Zn plasma using Langmuir probe
Reactive sputtering technique using Zn metal target represents one of the simplest and most effective technique which has been used by many researchers. In the present work, we investigate the properties of reactive magnetron sputtering plasma using Zn target. The magnetron sputtering plasmas were produced using radio…
Задача термоупругости для сплошного цилиндра с внешней кольцевой трещиной
Surface ring-shaped crack development in a heated up cylinder made of fragile material (inorganic glass) under cooling in water is examined. It is shown that the crack may develop under temperature stresses arising because of cooling medium from the cylinder surface and because of crack banks cooling by the medium get…

ESTUDO COMPARATIVO DA SOLDABILIDADE DOS TUBOS API 5CT Q125 E API 5CT C110 PARA APLICAÇÃO EM JUNTA CIRCUNFERENCIAL DE GASODUTO TERRESTRE
No Brasil, a Petrobras tem construido gasodutos e oleodutos para melhor atender a necessidade e a expansao do mercado interno na area de petroleo & gas. Com base nesse cenario, trata-se de um mercado promissor na fabricacao de dutos e na montagem de malhas para o escoamento de sua materia prima, seus produtos e deriva…
Conversion of Questionnaire Data
During the survey, respondents are asked to provide qualitative answers (well, adequate, needs improvement) on how well material control and accountability (MC&A) functions are being performed. These responses can be used to develop failure probabilities for basic events performed during routine operation of the MC&A…
Frequency response of the transformer model with simulated windings deformations and electric faults
The diagnostics of power transformers is very important in order to plan repairs and replacements of aged population of transformers operated in Poland and Europe. As the Frequency Response Analysis (FRA) is based on comparison of measured curves, which are not always available from previous measurements, the computer…
A novel in vivo protein refolding technique
Proteins perform their functions in their native folded states and misfolding of proteins may cause severe diseases, including Alzheimer's disease, Parkinson's disease, prion disease and diabetes. Understanding protein folding is important for us to engineer proteins to treat these diseases. For protein therapeutics,…

Geochemical responses of buried kimberlites in shallow groundwater in the Attawapiskat kimberlite field, James Bay Lowlands, Canada
Shallow groundwaters were examined in the Attawapiskat kimberlite region, James Bay Lowlands, Ontario, Canada in order to assess buried kimberlite impacts on shallow groundwater geochemistry. Kimberlite pathfinder metals consisting of light rare earth elements (LREEs), Ni, Cr, Ti, Ba, Rb, Cs, and the ratio of Mg/Ca ar…
The Luminescence Properties of New FED Phosphor MSi2N2O2∶Eu2+(M=Sr,Ba)
A series of new FED(Field Emission Display) green phosphors of MSi2N2O2:Eu2+(M=Sr,Ba) are synthesized by solid state reaction,and their luminescence properties under the excitation of different voltage and current density are studied.Under the excitation of electron beams,SrSi2N2O2:Eu2+ emits yellow green light with t…
Magnetic stresses analysis of a two speed, large power, synchronous motor in abnormal working conditions
This paper deals with the electromagnetic calculations of the stator magnetic stresses in the two-speed, large power, silent pole, synchronous motor. Prediction of such stresses is very important in understanding vibration phenomena of these special electrical machines. Because of non-symmetrical armature (stator) and…
Structural insights into TDP-43 in nucleic acid binding and domain interactions
TDP-43 is a pathogenic protein: its normal function in binding to UG-rich RNA is related to cystic fibrosis, and inclusion of its C-terminal fragments in brain cells is directly linked to neurodegenerative diseases, including frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS). To understa…
PVDF／PES／CA平板式共混超滤膜的研究
研究了致孔剂种类和用量对聚偏氟乙烯（PVDF）／聚醚砜（PES）／二醋酸纤维素（CA）共混平板膜结构和性能的影响，表征了共混超滤膜的水通量、截留率、孔隙率、收缩率和膜的断面形态等。结果表明，添加PES可以提高PVDF膜的尺寸稳定性，而添加1％CA可以提高PVDF／PES共混膜的亲水性，水通量显著增加。当PVDF／PES配比为9．5／0．5，致孔剂采用PEG20000、用量为60％时，其综合性能最优。
