Study on Catalysis of Cu-Fe Metal Composite Oxides to Thermal Decomposition Behavior of Bluestone

Nano-CuFe 2O4 catalysts with different Cu/Fe molar ratios (Cu nFe mO(n+1.5m) ) were prepared by hydrothermal method. The thermal decomposition performance of Cu nFe mO(n+1.5m) on CuSO 4 were determined with TG-DSC method to evaluate its catalytic activity and the roasted product was characterized by XRD. The results showed that Cu nFe mO(n+1.5m) had superior catalytic properties and efficiency to CuSO 4 crystals in 1:1 Cu/Fe molar ratios and 4% Cu nFe mO(n+1.5m) (in mass) contained. Under these conditions, the high and low temperature decomposition peaks of CuSO 4 were overlapped. The temperature and heat of decomposition were decreased by 29.5 °C and 112.1 J/g, respectively. The results were also confirmed by roasting experiments of CuSO 4·5H2O in muffle furnace in the presence of Cu nFe mO(n+1.5m) as catalyst at the same temperature.
DETERMINATION OF YOUNG’S MODULUS OF CARBON NANOTUBES USING MD SIMULATION

Molecular dynamics simulations were performed to determine the Young’s modulus of the single-walled carbon nanotubes (SWNT) and bamboo structural carbon nanoutbes (BSNT) models generated from the basic structure characteristics of graphite. The empirical Tersoff-Brenner potential and freestanding thermal vibration methods proposed by Krishnan et al. were used to determine interatomic forces and displacements of carbon atoms at room temperature ~300 K. The calculated average Young’s modulus of SWNT and BSNT model were <Y> = 1.424 and 0.604 TPa, respectively. In particular, the calculated Y value of the SWNT model is in good agreement with the previous measurements. Although, the evaluated Y value of the BSNT model, which represents heterogeneous nanotubes, was less than the pure the SWNT model, it still has strong and stiff mechanical properties comparing with other general bulk materials such as hardened steel (210 GPa). CNTs hold a promising future for the variety of potential applications in the nanotechnology field. rms
VŠB - Technical University of Ostrava Faculty of Electrical Engineering and Computer Science Data Compression Approach for Plagiarism Detection

In our digital era, the need for plagiarism detection tools is growing with the tremendous number of documents produced on daily basis in and outside academia in all fields of science. This includes, reports, students’ assignments, undergraduate and graduate theses and dissertations. While some students use cut and paste methods, some other students resort to different ways of plagiarism including, changing the sentence structure, paraphrasing and replacing words with their synonyms. This thesis focuses on creating textual plagiarism detection tools for detecting plagiarism of Arabic and Czech texts by implementing initial parts of a compression algorithm with its modifications where text similarity can be measured by compression-based similarity metrics. Next, it expands on this work by integrating this technique with a Czech synonyms thesaurus and a Czech stemmer to detect semantic plagiarism, including, paraphrasing and restructuring of Czech texts. On the other hand,
Predicting potential distribution of oriental fruit fly, Bactrocera dorsalis in Jiangxi Province, South China based on maximum entropy model

Oriental fruit fly, Bactrocera dorsalis Hendel (Diptera: Tephritidae) is a very destructive invasive pest of many tropical and subtropical fruits and vegetables. In order to effectively monitor and manage this pest, it is important to predict its potential geographical distribution in Jiangxi Province, south China. Maximum entropy (Maxent) was used to predict distributions of the fly in Jiangxi Province based on associations between known occurrence records and a set of environmental variables. The results suggested that the suitable areas for B. dorsalis infestations were mainly restricted to central and southern Jiangxi Province, with Latitude that ranged from 24 to 28°N. Northeast Jiangxi, northwest Jiangxi and the regions bording upon Yangtse River were predicted as unsuitable for B. dorsalis. The fit for the model as measured by AUC was high, with value of 0.978 for the training data and 0.965 for the test data, indicating the high level of discriminatory power for the Maxent. A jackknife test in Maxent indicated that mean temperature of coldest quarter with highest gain value was the most important environmental variable that restricted the expansion to north Jiangxi Province. Further research into the biology of the species and their ability to overcome barriers is necessary to explain niche differentiation, and to better understand invasion risk. Key words: Maxent, Bactrocera dorsalis, fruit fly, ecological niche model, potential distribution.
Confidence levels after practicum experiences of student teachers in Singapore: An exploratory study

The teaching practicum is regarded by many as an important part of teacher preparation where student teachers try to translate what they have learned into practice. This paper examines the confidence levels of student teachers as perceived by themselves, by their cooperating teachers and university supervisors in their knowledge and skills at the end of the two teaching practicum attachments in the third and fourth year of the 4‐year initial teacher preparation degree program. The results show a significant increase in confidence levels as perceived by all three parties at the end of each practicum, and even more so at the end of the second practicum. One implication of this study is that the practicum component in the teacher preparation program has been effective in meeting its expected objective of preparing the student teachers to be ready to assume their role as a full‐fledged teacher upon graduation.
Category theory for genetics I: mutations and sequence alignments

The present article is the first of a series whose goal is to define a logical formalism in which it is possible to reason about genetics. In this paper, we introduce the main concepts of our language whose domain of discourse consists of a class of limit-sketches and their associated models. While our program will aim to show that different phenomena of genetics can be modeled by changing the category in which the models take their values, in this paper, we study models in the category of sets to capture mutation mechanisms such as insertions, deletions, substitutions, duplications and inversions. We show how the proposed formalism can be used for constructing multiple sequence alignments with an emphasis on mutation mechanisms.
Effect factors of benzene adsorption and degradation by nano-TiO 2 immobilized on diatomite

Difference between adsorption of benzene by diatomite and nano-TiO2 immobilized on diatomite was investigated. And effects of temperature, light intensity, relative humidity, and initial benzene concentration on adsorption and degradation of benzene by nano-TiO2 immobilized on diatomite were also studied. The experimental results showed that when initial benzene concentration was 2.2 × 10-3 mg L-1, it could be degraded to below safe concentration (1.1 × 10-4 mg L-1) after 50 h when temperature was 20°C, but it just needed 30h at 35°C. When light intensity was 6750 Lx, it needed 30 h for benzene to be degraded to below safe concentration, but benzene could barely be degraded without light. When relative humidity was 50%, benzene could be degraded to 1.0 × 10-4 mg L-1 after 30 h, while its concentration could be reduced to 7.0 × 10-5 mg L-1 at the relative humidity of 80%.
Pharmacognostic and Antimicrobial Studies of Garcinia latissima Miq. Leaves (Clusiaceae)

Introduction: Garcinia latissima Miq known as Dolo magota (Maluku), is a medicinal plant belonging to the family Clusiaceae. The purpose of the research was to explore the phyto constituents present, pharmacognostic details, and their antimicrobial efficacy. Methods: The preliminary phytochemical components were qualitatively examined using the standard method systems. The antimicrobial screening was carried out using the good diffusion method and the minimum inhibitory concentration (MIC) using dilution method. Results: The phytochemical screening of different extract of G. latissima Miq leaves revealed the presence of tannins, saponins, and alkaloids and the results were tabulated. The ethyl acetate and methanolic extracts from its leaves showed antimicrobial activity especially for Bacillus subtilis, a positive bacteria; the hexane extract did not show any activity against the selected microba. Conclusion: The results of the phytochemical and bio-efficacy study revealed most valuable information and also support the continued sustainable use of this leaves in the traditional system of medicine.
Identifying efficiency trends for Queensland broad-acre beef enterprises

Productivity and efficiency improvements in agriculture have recently been targeted as Federal Government priorities in Australia. This research examined a dataset of 116 broad-acre beef enterprises from Queensland who participated in a program, Profit Probe, developed to improve management and profitability of enterprises. The aim of this research was to identify the sources, if any, of productivity growth for this sample of enterprises. Two potential sources of productivity growth were identified: 1. Technological progress involving a contraction (expansion) of the cost (output) frontier, and; 2. Efficiency improvements involving a convergence of the average production function toward the frontier. Given these two potential sources of productivity growth, the Stochastic Frontier Analysis approach was ideally suited to discern and measure technological change and efficiency change. Changes over time were observable due to the unbalanced panel nature of the data with 116 enterprises observed over a range of years from 1999 to 2008. A Cobb-Douglas functional form for the cost function was estimated following testing of the Translog form which showed higher order terms were not significant. An input oriented minimum cost frontier was chosen over the output oriented production frontier approach due to the consideration that output decisions were largely exogenous whilst input decisions were endogenous. Deterministic predictors of inefficiency were included using the panel inefficiency effects frontier of Battese and Coelli. There was no evidence of technological progress in the ten years from 1999 to 2008 for this sample of enterprises. There was however evidence of efficiency improvements despite preexisting high efficiency levels. In particular there was evidence that the Profit Probe program significantly contributed to efficiency improvements for participating firms with improvements continuing with repeated participation in the program. Additionally cost efficiency was shown to be an important component of profit maximisation but most likely was not a sufficient condition with output prices, as a quality and market indicator, being highly significantly related to profit levels.
Combined optical porosimetry and gas absorption spectroscopy in gas-filled porous media using diode-laser-based frequency domain photon migration

A combination method of frequency domain photon migration (FDPM) and gas in scattering media absorption spectroscopy (GASMAS) is used for assessment of the mean optical path length (MOPL) and the gas absorption in gas-filled porous media, respectively. Polystyrene (PS) foams, with extremely high physical porosity, are utilized as sample materials for proof-of-principle demonstration. The optical porosity, defined as the ratio between the path length through the pores and the path length through the medium, is evaluated in PS foam and found consistent with the measured physical porosity. The method was also utilized for the study of balsa and spruce wood samples.
Transitional Flow in a Rushton Turbine Stirred Tank

The way in which the single phase flow of Newtonian liquids in the vicinity of the impeller in a Rushton turbine stirred tank goes through a laminar-turbulent transition has been studied in detail experimentally (with Particle Image Velocimetry) as well as computationally. For Reynolds numbers equal to or higher than 6000, the average velocities and velocity fluctuation levels scale well with the impeller tip speed, that is, show Reynolds independent behavior. Surprising flow structures were measured—and confirmed through independent experimental repetitions—at Reynolds numbers around 1300. Upon reducing the Reynolds number from values in the fully turbulent regime, the trailing vortex system behind the impeller blades weakens with the upper vortex weakening much stronger than the lower vortex. Simulations with a variety of methods (direct numerical simulations, transitional turbulence modeling) and software implementations (ANSYS-Fluent commercial software, lattice-Boltzmann in-house software) have only partial success in representing the experimentally observed laminar-turbulent transition. © 2017 American Institute of Chemical Engineers AIChE J, 63: 3610–3623, 2017
Thermal and Textural Changes of Turkish Delight with Storage Relative Humidity

Lokum (Turkish delight) is a high sugar and starch containing food. Since the major deterioration factor affecting the storability of lokum is moisture gain or loss, the effect of the possible ambient conditions (32%, 53%, 75% RH and 15, 25, 35 °C) on weight change and firmness of lokum was determined to estimate its structural changes. The variations in thermal properties of lokum samples stored at different RH (32, 53, 65, 75, and 85% RH) were also determined. Increasing RH decreased glass transition of lokum samples, and two glass transitions (Tg) were observed at 75 and 85% RH. The presence of the second Tg could be related with phase separation which was increased with increasing moisture content and RH. Lokum should be kept at around 50% RH and 15 °C, higher storage RH’s and temperatures will cause the product to become unacceptable by the consumer within 20 days.
Current density enhancement nano-contact phase-change memory for low writing current

In this work, a phase-change memory (PCM) with self-assembled nanostructures and an oxidized thin phase-change layer is proposed and intensively investigated for low writing reset current by finite element analysis. Current density is significantly enhanced in our nano-contact memory because of the existence of nanostructures and oxidized phase-change layer. The writing current of our proposed memory is about 1/10-3/10 that of conventional cell, which is in good agreement with our experimental results. The heat efficiency in the nano-contact PCM cell is greatly improved and its power consumption can be as low as about 1/10 that of the conventional cell.
Supplier selection and order lot sizing using dynamic programming

In this paper, we consider a multi-period integrated supplier selection and order lot sizing problem where a single buyer plans to purchase a single product in multiple periods from several qualified suppliers who are able to provide the required product with the needed quality in a timely manner. Product price and order cost differs among different suppliers. Buyer’s demand for the product is deterministic and varies for different time periods. The problem is to determine how much product from which supplier must be ordered in each period such that buyer’s demand is satisfied without violating some side constraints. We have developed a mathematical programming model to deal with this problem, and proposed a forward dynamic programming approach to obtain optimal solutions in reasonable amount of time even for large scale problems. Finally, a numerical example is conducted in which solutions obtained from the proposed dynamic programming algorithm is compared with solutions from the branch-and-bound algorithm. Through the numerical example we have shown the efficiency of our algorithm.
Interactive comment on “Validation of cloud property retrievals with simulated satellite radiances: a case study for SEVIRI” by L. Bugliaro

However the authors do not explain clearly enough the limitations of the technique which I see as being primarily the dependence of the agreement between real and retrieved properties on the input values used to model the cloud fields. The most obvious (although probably not the only) of these is the ice crystal scattering properties which are consistent with the APICS retrieval and not with the CMSAF retrieval. This is mentioned too briefly by the authors when explaining better agreement between with the optical depth retrievals of the APICS retrieval with the simulated measurements, but they fail to mention clearly enough that this may also impact on the level of agreement between the other cloud properties (to a lesser or greater extent).
Gas in the Terrestrial Planet Region of Disks: CO Fundamental Emission from T Tauri Stars

We report the results of a high-resolution spectroscopic survey for CO fundamental emission from T Tauri stars. CO fundamental emission is frequently detected, with the likely origin of the emission in the circumstellar disk. An initial assessment of the line profiles indicates that the emission region includes the equivalent of the terrestrial planet region of our solar system, a result that suggests the utility of CO fundamental emission as a probe of disks at planet formation distances. Since fundamental emission is detected frequently from both close binary and apparently single stars, it appears that both low column density regions, such as disk gaps, and temperature inversion regions in disk atmospheres can produce significant emission. The estimated excitation temperature of the emitting gas is unexpectedly warm for the disk radii that they appear to probe. Thus, the surface gaseous component of inner disks may be significantly warmer than the surface dust component. We also detect CO emission from a transitional T Tauri star. Because fundamental emission from CO and its isotopes is sensitive to a wide range of gas masses, including masses ≪M⊕, CO fundamental emission may prove useful in measuring the residual gas content of dissipating disks. This may be an effective way to explore the gas dissipation timescale in inner disks and to thereby place constraints on the timescale for giant planet formation.

Ultrasonic Measurement of Change in Elasticity due to Endothelium Dependent Relaxation Response by Accurate Detection of Artery-Wall Boundary

Ross hypothesized that an endothelial dysfunction is considered to be an initial step in atherosclerosis. Endothelial cells, which release nitric oxide (NO) in response to shear stress from blood flow, have a function of relaxing smooth muscle in the media of the arterial wall. For the assessment of the endothelial function, there is a conventional method in which the change in the diameter of the brachial artery caused by flow-mediated dilation (FMD) is measured with ultrasound. However, despite the fact that the collagen-rich hard adventitia does not respond to NO, the conventional method measures the change in diameter depending on the mechanical property of the entire wall including the adventitia. Therefore, we developed a method of measuring the change in the thickness and the elasticity of the brachial artery during a cardiac cycle using the phased tracking method for the evaluation of the mechanical property of only the intima-media region. In this study, the initial positions of echoes from the lumen-intima and media-adventitia boundaries are determined using complex template matching to accurately estimate the minute change in the thickness and the elasticity of the brachial and radial arteries. The ambiguity in the determination of such boundaries was eliminated using complex template matching, and the change in elasticity measured by the proposed method was larger than the change in inner diameter obtained by the conventional method.
Development of an Animal Brain FE model

During this thesis a rat finite element (FE) model was developed and the relative methodology to operate was presented. The new rat brain FE model was developed using image processing techniques by extracting the geometry and mesh from magnetic resonance imaging (MRI). A new rat brain model was needed due to several limitations present in previous models Baumgartner D. et al (2009). Finite element simulations using a more detailed model were required to improve the understanding of the mechanisms responsible for injuries in the brain. The rat brain model developed in this thesis will be used in the future to simulate animal experiments carried out by Davidsson J. et al (2009). A method to get the geometry and the final model was developed in order to have the highest possible level of repeatability. Several limitations were found during the geometry generation due to the low quality of T1- weighted MR images and to the lack of T2- weighted MRI and computerized tomography (CT) scan. Also, a low control on the mesh generation process led to an excessive element density and tetrahedral elements concentration. A large amount of time was spent on the segmentation process having to use a wide range of methods with increasing user interaction. This has led to a low level of repeatability of the process. Several evaluations were made during this work, such as on original data, geometry result, mesh and simulations result. A correlation was found between original data (i.e. MRI, CT-scan) quality and simulation result accuracy.
