The currently available computational methods for the calculation of magnetic coupling constants with density functional theory have been reviewed. These methods include modern approximations to the exchangecorrelation functional, such as hybrid, range-separated and double-hybrid functionals, as well as approaches to…
In this paper, substitution of Fe 3+ for Al 3+ in the structure of aluminosilicate and aluminogermanate nanotubes was investigated at various mole ratios of Fe/Al from the mixed Al 2O3-Fe 2O3-SiO2 (GeO 2)-H2O solution in experimental conditions of 2 mM initial concentration and 2 day aging time at 98 0 C. The synthesi…
The global cement industry has been active in reducing its emissions from cement production through energy efficiency, alternative fuels and clinker substitution. Nevertheless, greenhouse gas emissions from cement production reached 2 billion tonnes in 2011 and the International Energy Agency estimates that the cement…
【This study aimed to measure the amount of sweating on 12 parts of the upper body using absorption fabric and analyze subjective sensations. The study was conducted with 9 male subjects in climate chamber controled at $30{\pm}0.5^{\circ}C$ , and $55{\pm}5%$ RH. The result was that sweating amount of the upper back par…
Cilj ovog rada je istražiti kako različiti pristupi dvaju klasifikacijskih društava, Det \\Norske Veritas i Lloyd's Register, utječu na dimenzije strukturnih elemenata. Kroz uvod i drugo poglavlje je pobliže objašnjena sama pojava udaranja u valove (eng. slamming). U trećem poglavlju su ukratko objašnjene razlike u pr…
The eukaryotic serine racemase fromDictyoste- lium discoideum is a fold-type II pyridoxal 5 0 -phosphate (PLP)-dependent enzyme that catalyzes racemization and dehydration of both isomers of serine. In the present study, the catalytic mechanism and role of the active site residues of the enzyme were examined by site-d…

Boron neutron capture therapy (BNCT) is based on selective accumulation of 10 B carriers in tumor followed by neutron irradiation. We previously proved the therapeutic success of BNCT mediated by the boron compounds boronophenylalanine and sodium decahyd- rodecaborate (GB-10) in the hamster cheek pouch oral cancer mod…
Recently, energy-saving technology is rapidly becoming a crucial issue for mankind due to the depletion of natural resources. From this perspective, every automobile manufactures are trying to develop light materials and to validate safety with environmental consideration. In this study, we developed clutch connector…
Crystalline group IV semiconductor materials are essential components in microelectronics, solar cells, and sensor applications.
利用SMT全自动回流焊机和高温恒温试验箱,制备出经2次回流焊且不同时效处理时间的Sn-Ag3.0-Cu0.5/Cu焊点试件,对其金属间化合物（IMC）的厚度进行测量,发现其厚度的增长与时效时间的平方根近似成线性关系.采用统一粘塑性Anand本构模型来描述焊点的力学性能,运用有限元计算软件ANSYS对PBGA构件进行热循环模拟,对其在不同IMC厚度下的应力和应变响应进行分析.结果表明,芯片右下方焊点右上角热循环结束后累积的等效塑性应变最大,是整个PBGA构件的关键焊点;随着IMC厚度的增加,关键焊点热循环过程中的等效应力水平不断降低,相应剪切塑性应变范围△γ不断增大,热疲劳寿命Nf则不断降低：升温和高温保温过程中剪切塑性应变的增加量…
Abstract: In this work we present cross sections for low energy positron elastic scattering by molecules methane (CH4), fluoromethane (CH3F), difluoromethane (CH2F2), trifluoromethane (CHF3), and tetrafluoromethane (CF4), for energies up to 10 eV, using two different basis set in the description of the collision proce…
Identification of the aging condition and the failure probability of oil-paper insulation in transformer is important for improving the reliability of electric power transmission system and applying life cycle cost (LCC) management to electrical equipment. Based on data obtained in a series of multi-accelerated-aging…
This thesis is based upon syntheses and characterization of new quaternary oxo-and chalcohalides of cobalt and cadmium, which include selenium ions (Se4+) that have a stereochemically active lone pair. A total of five new compounds Cd4Se2O7Cl2, Co4(SeO3)3Cl2, Co3Se4O10Cl2 and Co2V2Se2O11 are crystalline while Cd2SeCl2…
In this paper, we look at the possibility to implement the algorithm to construct a discrete line studied by the first author in cellular automata. It turns out that such an implementation is feasible.
The general method to realize series connection in thin film PV modules is monolithical interconnection through a sequence of laser scribes (P1, P2 and P3) and layer depositions. This method however implies that the deposition processes are interrupted several times, an undesirable situation in high volume processing.…
Hydatid disease is a disease which is endemic in our country. Cardiac hydatid cyst is rare even in areas where the disease is endemic. Fatal complications, early diagnosis and treatment is important because it is common. Two-dimensional echocardiography, especially computed tomography (CT) and magnetic resonance imagi…
Silicon-based technology has experienced phenomenal growth in the last few decades. Si MOSFET gives us higher performance when we reduced its dimensions but when it reaches its limiting size, various shortchannel effects appear to affect its performance. In that case the semiconductor industry is looking for different…
During the last decade, cycloparaphenylenes (CPPs) have attracted the attention of chemists. Indeed, this interesting class of molecules represents the shortest section of an armchair carbon nanotube, offering a potential template for the selective synthesis of carbon nanotubes. Cycloparaphenylenes are also interestin…
Offshore pipelines may be subjected to impact by anchor and trawl gear. An anchor impact will drag the pipeline out of its position, before it is released and the pipe straightens, due to the rebound and large axialforces. Damage and fracture may occur due to the highly complex stress and strain history in the pipe.Th…
