The article presents the method of defining the limiting permissible deformations which was applied for the assessment of technical condition of the panel buildings located at the subsided areas of Perm Territory.
采用金相显微镜、差热分析（DSC）和透射电镜（TEM）研究复合添加0.03%Sc 与0.12%Zr 及固溶处理对Al-9.0Zn-2.8Mg-2.5Cu合金组织性能的影响，以及添加少量（小于0.1%）的Sc是否能得到高性能铝合金。结果表明：添加0.03%Sc与0.12%Zr可以使Al-9.0Zn-2.8Mg-2.5Cu合金出现“花瓣状”的Al3（Sc,Zr）析出相；Al3（Sc,Zr）粒子对位错有强烈的钉扎作用，明显抑制 Al-9.0Zn-2.8Mg-2.5Cu 合金在均匀化和挤压过程中的再结晶；多级固溶明显优于单级固溶，可以在添加少量Sc（小于0.1%）时，避免Al-9.0Zn-2.8Mg-2.5Cu发生再结晶：（420°C，3…
Among various electrochemical devices that have been developed for energy storage and conversion, electric double layer capacitors (EDLCs) and direct methanol fuel cells (DMFC) have received much research attention. Nanostructured carbon materials have been playing an important role in the development of these devices…

Waste – water from pharmaceutical plant was collected using composite sampling. This was characterized and treated using native clay samples collected from selected clay deposits in Edo State of Nigeria. The aim was to find out the effectiveness of clay as coagulant in waste water treatment processes. The results of t…
This works investigate the effects of addition FeNO3 on optical properties of poly-vinyl alcohol(PVA). The specimens were prepared by adding FeNO3 to the solution of poly-vinyl alcohol with weight percentages from FeNO3 are(0,1,2,3)wt.%. The experimental Results show that the absorbance of (PVA-FeNO3)composites increa…

First clinical study of prostate cancer detection with a dual sensor combining tactile resonance technique with fiber optical Raman spectroscopy
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating s…
The basics of the oxidation mechanism of different alkanes within zeolites and over molybdenum oxide surfaces were studied employing state of the art computational modelling. \nIt was shown that the constrained environment inside MFI, MFS and MOR induces terminal selectivity on the reaction of 6-, 8- and 10- term line…
Magnetic resonance imaging (MRI) is the best noninvasive technique in clinical diagnosis. However, MRI is not so sensitive like fluorescence imaging and nuclear medicine. To overcome this problem, iron oxide nanoparticles are used as contrast agent for MRI enhancement at tissue, cellular and molecular levels. Novel as…
As the analysis of the state of foundry shops shows, one of the «bottlenecks» are molding shops, but the main problem in these shops is the wear of molding equipment. Therefore, the studies on the development of measures for the reconstruction of the molding equipment, considering it as a part of the technical reequip…
Kiselalgsfloran på alla de undersökta lokalerna i Dalälvens avrinningsområde indikerar att tolv av de 16 undersökta lokalerna har hög ekologisk status år 2012. Lokalerna är näringsfattiga och fritt från lättnedbrytbara organiska föroreningar. Fyra lokaler (Ljusterån, Långshytteån, Broån, Årängsån) hamnade i god eller…
A method of admissible error calculation of cutting tool mounting surfaces for installation of replaceable inserts, allowing creation of one algorithm for different types of cutting tools is proposed in this article. Deviations of dimensions of parts in the tool dimension chain are taken into account for accuracy calc…
Ab initio calculations,based on norm-conserving nonlocal pseudopotentials and density functional theory(DFT),are performed to investigate the structural,elastic,dielectric,and vibrational properties of aluminum arsenide(AlAs) with a zinc-blende(B3) structure and a nickel arsenide(B81) structure under hydrostatic press…
The tendency towards the use of thicker and stronger twines in the aft end of trawls coincides with a preference for maximum and easy mesh opening in this area to allow the release of small fish. This makes the resistance to opening of netting panels a key factor in the selective performance of fishing gears. In panel…
3,3′-dimethyl-9,9′-bianthracene was synthesized from 2-methyl-anthraquinone through two steps reactions,and its structure was determined by means of 1H NMR spectra and elemental analysis.The synthetic pathway has more advantages such as few reaction steps,high yield,easy purification and so on.Moreover,the effects on…
Syftet: Syftet med studien är att undersöka hur mycket de vertikala blickriktningar 30° uppåt, 30° nedåt och rakt fram påverkar det binokulära samarbetet mellan ögonen vid närarbete. De synförmågor som utvärderas är ackommodationsamplitud, heteroforier, konvergensnärpunkt och fusionsreserver. Metod: Studien innefattad…
Electrode water heaters are widely used in farming. Hot water and heat consumption on livestock farms changes dramatically within a day. Variable heat loads considerably complicate the conditions of heat supply. The research subject is an electrode water heater of static type with coaxial electrodes. The main disadvan…
