Comparison of transfer functions using estimated rational functions to detect winding mechanical faults in transformers As it is found in the related published literatures, the transfer function (TF) evaluation method is the most feasible method for detection of winding mechanical faults in transformers. Therefore, in…

Structuration in solutions has defined by rheological method with rotation viscometer. Shown influence of solvent nature (methyl ethyl ketene: toluene) to strength properties and structures of fil…
High pure, single phase, free of voids and crack-free AgGaSe2 single crystals have been grown by vertical Bridgman technique with steady ampoule rotation. Powder X-ray diffraction, High-resolution X-ray diffraction, Micro-Raman scattering and Optical studies have been performed and the results are discussed in detail.
The paper gives a state-of-the-art report on splitting of beams loaded perpendicular to grain by connections. Special emphasis is placed on simple analytical models based on fracture mechanics. A new simple model is presented, existing models are reviewed and relations between the models are shown, and an existing mod…
藍藻類がブルーム状態を呈する島根県三瓶ダム湖において，2009年9月17日12：00から18日14：00まで2時間間隔でアオコの鉛直移動に関する調査を行った。その結果，日周的な水温成層構造を形成する時間帯において鉛直移動が観測され，深度0.5 mから5 mおよび9.5 mまでの沈降速度はそれぞれ0.35 m・h-1，0.73 m・h-1，深度5 mおよび9.5 mから表層への浮上速度は0.41 m・h-1，0.79 m・h-1であった。日周的な鉛直移動のサイクルは，12：00に表層に展開し，14：00に沈降を始め，翌日の深夜0：00に最も沈降した状態となった。浮上は深夜2：00に観測され始め12：00に最も表層に展開した後，再び沈…
以NaBH4为还原剂, 制备了金与铂物质的量比为49∶1的金铂纳米合金(GP). 用兔抗人绒毛膜促性腺激素抗体(RhCG)修饰AuPt获得了免疫纳米合金探针(GP-RhCG). 在pH 5.8磷酸氢二钠-柠檬酸缓冲溶液及KCl存在的条件下, GP-RhCG探针发生非特异性聚集, 在590 nm处有一个较强的共振散射峰. 当有人绒毛膜促性腺激素(hCG)存在时, 聚集的GP-RhCG探针与hCG发生特异性结合, 生成分散性较好的GP-RhCG-hCG免疫复合物, 导致590 nm处共振散射峰强度降低. 其共振散射峰强度降低值ΔI590 nm与hCG浓度在6.67～86.7 ng/mL范围内呈现良好线性关系. 免疫反应液中形成的GP-…
Instead of highly symmetrical T-symmetry cages common in self-assembly, the p-NMe(2)-substituted triphosphine CH(3)C{CH(2)P(4-C(6)H(4)NMe(2))(3) gives open, polar C(3) symmetry cages [Ag(6)(triphos)(4)X(3)](3+) which lack one of the expected face-capping anions; despite its subtlety this difference occurs selectively…
Optical constants of pulsed laser ablated amorphous high-k LaGdO 3 (a-LGO) thin films on quartz (0001) substrates were measured and analyzed. Refractive index ( n ∼ 2.05–2.29) and extinction coefficient ( k ∼ 0.004–0.017) were parameterized by analysis of the UV/Visible transmission spectra employing a Cauchy-Urbach d…
Skeleton castings macrostructure can be shaped in many ways, by choosing an appropriate material of cores and manufacturing technologies. Important factor, which puts foundry techniques over the other technologies of periodic cellular materials, is ability to adjust mechanical properties by changing the microstructure…
In paper is presented technology of bimetallic layered castings based on founding method of layer coating directly in cast process so-called method of mould cavity preparation. Prepared castings consist two fundamental parts i.e. bearing part and working part (layer). The bearing part of bimetallic layered casting is…

The quenching of photoluminescence (PL) inten…
We present a detailed study of the wavelength influence in pulsed laser annealing of amorphous silicon thin films, comparing the results for material modification at different fluence regimes both in the three fundamental harmonics of standard DPSS laser sources, UV (355 nm), visible (532 nm) and IR (1064 nm), and KrF…
Proton transport along different axes in an organic-inorganic compound [(C(6)H(10)N(2))(2)(SO(4))(2)·3H(2)O](n) (1) was investigated, revealing that proton transport is not only influenced by the structure of the proton transport pathway, but also by the order-disorder extent of proton carriers.
Photo-controlled metal-ion (Zn(2+) and Cd(2+)) release in aqueous micelle solution (tris-HCl, pH = 7.4) has been described using 2-((2-mercaptophenylimino)methyl) phenol as ligand.
