A relaxation of stress in the elements of constructions is considered and an approach is proposed for solution of corresponding problems. It is notable that this approach is based on a modification Boltzmann’s principle superposition of fraction creep deformations. This modification reduces the noted problems to solut…
. These factors are identified as significant for the height of the ethyl hydrogenation barrier on Pd. Moreover, we show that butyl hydrogenation on Pd is also governed by very similar interactions, which suggests a broader applicability of our conclusions. This study highlights the complexity of alkyl hydrogenation a…
The strong light-matter interaction in the atomically thin transition metal dichalcogenides (TMDCs) has allowed the use of optical spectroscopy to investigate these materials in great depth. It has been shown that optoelectronic properties of ultrathin TMDCs are remarkably different from their bulk counterparts. Among…
The article considers thermophysical characteristics of radioactive graphite – water vapor system in temperature range 373-3273K. The research was made by thermodynamic modeling method using TERRA software. We determined 4 temperature intervals in which changes of thermophysical characteristics of radioactive graphite…
Nonvolatile control of perpendicular magnetic anisotropy (PMA) is of great technological importance for low-power spintronic devices. In this study, we successfully achieved ferroelastic strain-mediated nonvolatile tuning of PMA at room temperature in (Co/Pt)3/(1 1 1) Pb(Mg1/3Nb2/3)O3-PbTiO3multiferroic heterostructur…
Some novel traveling waves and special solutions to the 1D nonlinear dynamic equations of rod and beam of power-law materials are found in closed forms. The traveling solutions represent waves of high elevation that propagates without change of forms in time. These waves resemble the usual kink waves except that they…
現在の食品中の放射性物質に関する基準値は，134Cs, 137Cs, 90Sr, 106Ru, Pu, を規制対象とし，放射性セシウムに代表させ設定されている。土壌中の放射性核種の濃度比等を基に導出されているが，海産物については，セシウムとそれ以外からの線量が等量になると仮定している。今回，モニタリングデータを基に線量への寄与の検証を試みたところ，セシウム以外からの寄与は基準値策定時の仮定よりも小さかった。
The aim of this work is to synthesis of pure γ- CuI nanoparticles, by employing adaptation of the exploding wire phenomena in needle-plate geometry. γ- CuI p-type semiconductor is one of the promising materials it has a wide energy bad gap (3.1 eV) and unusual optical properties. It is very useful as hole collector in…
This paper deals with a cylindrical steel-concrete load-bearing unit. The feature of the unit is a steel mesh casing that is made from the expanded metal mesh. The optimal parameters of the suggested footing are determined taking into account anisotropy, i. e. different strength and rigidity in different directions th…
This article shows an attempt to prepare poly(acrylonitrile-co-methyl acrylate)/polyaniline (PANMA/PANI)-based nanocomposite with silver nanoparticle (AgNP) and cellulose-silver nanoparticle (Cell-AgNP). Silver nanoparticles have been prepared by photoreduction of silver nitrate in UV light in the presence of poly(N-v…
The study reported in this paper concerned development of such microstructure of high-chromium (24 % Cr) cast iron which could secure high abrasive wear resistance of die inserts used to fabricate stampings from refractory materials. It was found that by increasing the cast iron cooling rate as a result of thermal int…
We show that for any set of $n$ distinct points in the complex plane, there exists a polynomial $p$ of degree at most $n+1$ so that the corresponding Halley and Schröder map for $p$ has the given points as a super-attracting cycle. This improves the result in [1], which shows how to find such a polynomial of degree $3…
In the present work, the behaviour of ZrO2 – Y2O3 coatings in contact with molten salts at 500 °C has been studied. The coatings were prepared by sol-gel and deposited by dip-coating on AISI 304 specimens previously prepared by sanding and polishing. The behaviour in contact with molten salt was studied through static…
How to arrange a packing of spheres is a scientific question that aroused many fundamental works since a long time from Kepler’s conjecture to Edward’s theory (S. F. Edwards and R.B.S Oakeshott. Theory of powders. Physica A, 157: 1080-1090, 1989), where the role traditionally played by the energy in statistical proble…
In a dry biorefinery scheme, the separation of plant materials into powders rich in the constituents of interest is a crucial step. In recent years, electrostatic separation of agri-resources has sparked a growing interest for its potentialities, but optimization efforts remain to be done especially in case of fine po…
水道水の電気分解により得た次亜塩素酸水と水道水を使用し，温水洗浄便座の洗浄ノズルの除菌効果を比較検討した．約105～106 cfu/mLの大腸菌および緑膿菌を付着させた洗浄ノズルに対し水道水でリンスと吐水を5回繰り返すと，付着菌数は4桁減少した．塩素濃度1.5 ppm含有の次亜塩素酸水によるリンスでは，大腸菌および腸球菌においてリンス3回目から検出限界以下になり，洗浄ノズル表面の細菌も検出限界以下になった．洗浄ノズルの衛生保持には，水道水よりも次亜塩素酸が有効であることが示唆されたが，緑膿菌では次亜塩素酸水を使用しても完全に除菌できなかった．温水洗浄便座を使用する対象者と場所を考慮する必要があると考えられる．
Pyridine moiety-appended doubly bridged cyclotricatechylene (CTC(Py) 2 (OH) 2 ) was synthesized and characterized. Solid state studies show that CTC(Py) 2 (OH) 2 forms a capsular assembly in the presence of water but a polymeric assembly in its absence.
David Schiffrin opened discussion of the introductory lecture by Serge Lemay: After listening carefully to your challenging presentation I was left wondering if you believe in the validity of modeling as a reasonable approach to solving scientific issues? Serge Lemay responded: I
Lanthanide-based nanotechniques continue to attract considerable attention due to their current range of applications and broad potential in optical devices and biomedicine.
COMSOL finite element software was used to establish a solid-liquid coupling biphasic model of articular cartilage and a microscopic model of chondrocytes, using modeling to take into account the shape and number of chondrocytes in cartilage lacuna in each layer. The effects of cyclic loading at different frequencies…
