Decommissioning Cost Calculation Code Based on Proposed Standardised List of Items for Costing Purposes With Integrated Material and Radioactivity Flow Control and Integrated Cost Allocating System

In 1999 was issued commonly by EC, IAEA and OECD the document “A Proposed Standardised List of Items for Costing Purposes in the Decommissioning of Nuclear Installations” (PSL). The main aim of this document was to establish a standard platform for structure of presented decommissioning costs. The decommissioning costs calculated in various projects have in general different structure and for presenting the decommissioning costs in PSL structure, additional recalculation or rearrangement of data are needed. This can increase the uncertainty of data or it is not sure if they really reflect the cost defined in the PSL structure. The paper describes a newly developed cost calculation code, which respect the PSL structure. The calculated costs data are compatible with the standardised structure. The code is intended to use for decommissioning planning of a NPP with a non-standard radiological situation, shutdown after an accident For this purpose the code has an integrated material and radionuclide resolved radioactivity flow control system in calculation process which enables a direct calculation link between the input material and radiological inventory data and the calculated costs and other decommissioning parameters for increasing the accuracy of calculated data. The code has an integrated cost allocating system for generating of user defined working breakdown structure of the decommissioning project with allocated costs calculated in PSL structure. The working breakdown structure can be on-line optimised using the standard Microsoft Office Project Planning tool software.Copyright © 2003 by ASME
Study of a GPS satellite selection policy to improve positioning accuracy

The four dimensional accuracy of GPS positioning using four satellites at every instant is reexamined. User receivers usually select suitable four satellites that have best geometry based on PDOP or GDOP. However, it is more reasonable to select a set of four satellites that has minimum VDOP for measuring vertical position, while to select a set of four satellites that has minimum HDOP for measuring horizontal position. In this studies, we propose a method of using VDOP and HDOP as the criteria to select the set of four satellites used for measuring vertical and horizontal positions respectively, and compare its performance with that of the conventional method by computer simulation. It is clarified that the combinations of the four satellites that minimize VDOP, HDOP and PDOP are generally different each other, and limited amount of improvement in VDOP and HDOP is obtained by optimizing them separately. Dependence of the amount of the improvement on latitude and mask angle is also examined. <<ETX>>
Comprehensive Comparative Analysis of the GATA Transcription Factors in Four Rosaceae Species and Phytohormonal Response in Chinese Pear (Pyrus bretschneideri) Fruit

The GATA gene family is one of the most important transcription factors (TFs). It extensively exists in plants, contributes to diverse biological processes such as the development process, and responds to environmental stress. Although the GATA gene family has been comprehensively and systematically studied in many species, less is known about GATA genes in Chinese pears (Pyrus bretschneideri). In the current study, the GATA gene family in the four Rosaceae genomes was identified, its structural characteristics identified, and a comparative analysis of its properties was carried out. Ninety-two encoded GATA proteins were authenticated in the four Rosaceae genomes (Pyrus bretschneideri, Prunus avium, Prunus mume, and Prunus persica) and categorized into four subfamilies (Ⅰ–Ⅳ) according to phylogeny. The majority of GATA genes contained one to two introns and conserved motif composition analysis revealed their functional divergence. Whole-genome duplications (WGDs) and dispersed duplication (DSD) played a key role in the expansion of the GATA gene family. The microarray indicated that, among P. bretschneideri, P. avium, P. mume and P. persica, GATA duplicated regions were more conserved between Pyrus bretschneideri and Prunus persica with 32 orthologous genes pairs. The physicochemical parameters, duplication patterns, non-synonymous (ka), and synonymous mutation rate (ks) and GO annotation ontology were performed using different bioinformatics tools. cis-elements respond to various phytohormones, abiotic/biotic stress, and light-responsive were found in the promoter regions of GATA genes which were induced via stimuli. Furthermore, subcellular localization of the PbGATA22 gene product was investigated, showing that it was present in the nucleus of tobacco (Nicotiana tabacum) epidermal cells. Finally, in silico analysis was performed on various organs (bud, leaf, stem, ovary, petal, and sepal) and different developmental stages of fruit. Subsequently, the expression profiles of PbGATA genes were extensively expressed under exogenous hormonal treatments of SA (salicylic acid), MeJA (methyl jasmonate), and ABA (abscisic acid) indicating that play important role in hormone signaling pathways. A comprehensive analysis of GATA transcription factors was performed through systematic biological approaches and comparative genomics to establish a theoretical base for further structural and functional investigations in Rosaceae species.
Development and Psychometric Validation of Geography Interest Inventory for Secondary School Students

In recent time, the number of students’ academic performance in geography in secondary schools in Delta State, Nigeria has been on the declined. Therefore, it becomes imperative to know the students interest level in the subject. The study is on development and psychometrics validation of geography interest inventory. The instrument has 27 items. The instrument was administered to a sample of 494 secondary students in Delta State, Nigeria. The sample was randomly split in two halves. The first sample 247 was used for Exploratory Factor Analysis (EFA). The results of the Exploratory Factor Analysis resulted in Four Factor Solution that is emotion, value, Knowledge and engagement. To validate the structure or factors obtained from the EFA, a confirmatory factor analysis was conducted using second sample of 247. The result of model fit in term of TLI (0.904), CFI (0.917), RMSEA (0.066) and SRMR (0.63) were above the recommended cut of o.90 for CFI, TLI and less than 0.08 for RMSEA and SRMR respectively. Furthermore, the study also indicates that items loading in the respective dimension were significant. Therefore, the geography interest inventory is valid and reliable.
COMPACT DUAL-MODE OPEN STUB-LOADED RESONATOR AND BPF

A compact dual-mode open stub-loaded resonator and bandpass fllter (BPF) is proposed in this paper. The resonator, which is formed by attaching a disc-shaped open stub and circular open stubs in pairs to a high impedance microstrip line, generates two operating modes in the desired band, and the even-mode resonance frequency can be ∞exibly controlled by the disc-shaped open stub at central plane, whereas the odd-mode one is flxed. The four transmission zeros are created to sharpen the rejection skirt, suppress two high harmonic resonant modes and deepen upper-stopband, respectively. Experimental results of the dual-mode fllter which incorporates this resonator with parallel-coupled feed line with tuning stub at 5.8GHz show good agreement with the simulated ones. The size for the resonator is only 4:7 £ 3:4mm (0:29‚g £ 0:21‚g in which ‚g is the guided wavelength of 50› microstrip at 5.8GHz).
EXPLORING CONCOMITANT CONCEPTS IN THE DISCUSSION ON THE CIRCULAR ECONOMY: A BIBLIOMETRIC ANALYSIS OF WEB OF SCIENCE, SCOPUS AND TWITTER

A growing interest in the circular economy, which is seen in the intensification of public discourse, could lead to a danger of blurring the concept and introducing inefficiency in implementing circular economy-based solutions. This study explores the trend in concomitant or accompanying concepts of the discussion about the circular economy themes understanding regarding scientific publications (3,486 publications from Web of Science and Scopus) and popular (non-scientific) domain (represented by 106,504 tweets) in the years 2011–2018. By employing text mining, we calculated the Jaccard similarity index divided into years. The results reveal changes over time in themes accompanying the circular economy discussion and a trend of rising recognition of research-related keywords in general public discussion, with unweighted similarity reaching 39.44% in 2018. Our Twitter keyword research perspective indicates the need to consider the consumer’s role in the development of the circular economy – through keywords that are closely related to consumers’ daily activities.
New experimental system for base-isolated structures with various dampers and limit aspect ratio

A new experimental system of base-isolated structures is proposed. There are two kinds of dampers usually used in the base-isolated buildings, one is a viscous-type damper and the other is an elastic-plastic hysteretic-type damper. The base-isolated structure with a viscous damper and that with an elastic-plastic hysteretic damper are compared in this paper. The viscous damper is modeled by a mini piston and the elastic-plastic hysteretic damper is modeled by a low yield-point steel. The capacity of both dampers is determined so that the dissipated energies are equivalent at a specified deformation. When the capacity of both dampers is determined according to this criterion, it is shown that the response of the base-isolated structure with the elastic-plastic hysteretic damper is larger than that with the viscous damper. This characteristic is demonstrated through the comparison of the bound of the aspect ratio. It is shown that the bound of aspect ratio for the base-isolated structure with the elastic-plastic hysteretic damper is generally smaller than that with the viscous damper. When the base-isolated structure is subjected to long-duration input, the mechanical property of the elastic-plastic hysteretic damper deteriorates and the response of the base-isolated structure including that damper becomes larger than that with the viscous damper. The effect of this change of material properties on the response of the base-isolated structure is also investigated.
Simu-D: A Simulator-Descriptor Suite for Polymer-Based Systems under Extreme Conditions

We present Simu-D, a software suite for the simulation and successive identification of local structures of atomistic systems, based on polymers, under extreme conditions, in the bulk, on surfaces, and at interfaces. The protocol is built around various types of Monte Carlo algorithms, which include localized, chain-connectivity-altering, identity-exchange, and cluster-based moves. The approach focuses on alleviating one of the main disadvantages of Monte Carlo algorithms, which is the general applicability under a wide range of conditions. Present applications include polymer-based nanocomposites with nanofillers in the form of cylinders and spheres of varied concentration and size, extremely confined and maximally packed assemblies in two and three dimensions, and terminally grafted macromolecules. The main simulator is accompanied by a descriptor that identifies the similarity of computer-generated configurations with respect to reference crystals in two or three dimensions. The Simu-D simulator-descriptor can be an especially useful tool in the modeling studies of the entropy- and energy-driven phase transition, adsorption, and self-organization of polymer-based systems under a variety of conditions.
Low-strain, quantum-cascade-laser active regions grown on metamorphic buffer layers for emission in the 3.0-4.0 μm wavelength region

We have investigated metamorphic buffer layers (MBLs), as so-called virtual substrates, for accessing a compositional range of In x Ga 1-x As/Al y In 1-y As superlattice (SL) materials which would otherwise be prohibited due to excessive strain when grown on conventional substrates. Such materials have application in the realisation of high-performance Quantum Cascade Lasers (QCLs) of short emission wavelengths (i.e., ≤4.0 μm). Simulation studies suggest that significant enhancement of performance in terms of reduced device temperature sensitivity and reduced thermal resistance is possible over conventional InP-substrate devices by employing MBL-based QCL designs on a GaAs substrate. Furthermore, such devices would exhibit significantly lower strain compared to conventional QCLs on InP emitting within the 3.0-4.0 μm wavelength region. To improve the planarity of MBL top surfaces, we employ chemical mechanical polishing (CMP) prior to the growth of the QCL SL structures. 20-period In x Ga 1-x As (wells)/Al y In 1-y As (barriers) SLs are grown by metalorganic vapour phase epitaxy (MOVPE) on an InGaAs step-graded, hydride vapour phase epitaxy (HVPE)-grown MBL. Employing CMP on the top of the MBL, prior to the SL growth, results in significantly improved X-ray-diffraction SL fringes. Electroluminescent devices, incorporating a single stage of QCL-SL active-region material grown on an MBL subjected to CMP, demonstrate intersubband emission near 3.6 μm.
Normative Fitness in Undergraduate Exercise Science Students: How Do They Compare?

ABSTRACT The purpose of this study was to report normative physical fitness data for Exercise Science undergraduate students and compare the findings with criteria published by the American College of Sports Medicine (ACSM). 514 participants (males, n = 204; females, n = 310) aged from 18 to 29 years participated in this descriptive study. Pre-exercise heart rate and blood pressure, body mass index, waist circumference, skinfold thicknesses to estimate total body fat percentage (BF%), estimated maximal oxygen intake (VO2max), and muscular endurance were evaluated. Percentiles were calculated and compared to those from the ACSM, with hypothesis testing of the medians. The median BF% for male students was leaner (p < 0.001) than criterion standards. VO2max was lower compared to the published median in both sexes (p < 0.001). Students performed on par with ACSM-published muscular endurance assessments. Exercise Science students are not fitter than the normative data published by the ACSM.
Presenting a risk management model for residential wooden structures in earthquake-prone areas of Iran

A risk management model was applied to residential wooden structures in earthquake-prone areas of Iran. The statistical population of the study consisted of academic and organizational experts. Thirty individuals were interviewed using a purposive non-random sampling technique and the data adequacy and saturation principle. A semi-structured interview was used to collect the required data. The validity was assessed using content and construct validity. Cronbach’s alpha coefficient was used to measure reliability, and it was greater than 0.7 for all components. In the qualitative section, data analysis was performed via a theoretical coding method that used the Grounded Theory approach, and the model was presented using interpretive structural modeling. The results revealed that the dimensions of the seismic related risks in the implementation of wooden residential structures in earthquake-prone areas of Iran, which included the internal risks (employer risk, implementation risk, scheduling risk, manpower risk, and design risk) and the external risk (risk due to political, economic, legal, and natural factors), were the most important risks.
The Effects of Texting and Driving on Hazard Perception

Hazard perception has received little attention compared to measures of vehicle control in studies exploring the effects of texting on driving performance, despite being a more direct measure of crash risk. Furthermore, the driver strategies attempting to moderate such distraction are not well understood. The current study attempts to address these two facets of texting while driving. Participants (10 male; 10 female) drove a low fidelity simulator that measures situational awareness, while text messaging in order to assess hazard perception performance. Participants were required to identify and appropriately respond to events that would result in a collision. Two text message conditions (i.e., copying and alphabetizing a 5-letter string) were used to compare low vs. high cognitive load, respectively. Participants missed more hazards in the alphabetize-text compared to the copy-text and driving only conditions. Signal Detection Theory (SDT) analyses revealed the adoption of a more liberal response bias (B”) (i.e., participants increased false) when required to copy the text message but not when required to alphabetize. Last, participants were slower to react to hazards in the alphabetize-text condition compared to the copy-text and driving only conditions. These findings suggest that the impact of text messaging on the detection of driving hazards depends in part, on the cognitive load imposed by the text messaging task and the adoption of strategies to compensate for the interference on the driving task.
Modelling and control of DC-DC converters

This tutorial article shows how the widely used analysis techniques of averaging and linearisation are applied to the buck or step-down DC-DC converter to obtain simple equations which may then be used for control design. Three common control methods are described. Their principal characteristics are illustrated using Matlab and the Simulink block diagram system along with experimental results. The analysis procedures described may be applied directly to other DC-DC converters and the principles may be extended to more complex power electronic systems.
CAN GOVERNMENT FUNDING REVIVE ZOMBIE ENTERPRISES? EVIDENCE FROM LISTED CHINESE MANUFACTURING ENTERPRISES

This study tests how different types of government funding affect the recovery of zombie enterprises in the manufacturing sector of China. The results show that funding for production and innovation can revive zombie enterprises in expanding industries, while funding for interest cannot. Furthermore, funding for production and innovation can share costs, increase investment in selling or innovation, and promote the scaling down of businesses through external governance effects, helping zombie enterprises to recover. Finally, none of the funding types can revive zombie enterprises in contracting industries; these can recover only through access to larger overseas markets.
Characterization of multilayer depositions of DVD-RAM disks

A method for rapid characterization of DVD multilayer depositions is presented. With a single optical measurement the devised method allows to determine the values of the refractive index (n) and of the extinction coefficient (k) for the wavelength comprised between 400 and 900 nm, and the film thickness. The analysis of these optical and physical properties provides a mean for tracking back possible process deviations in the multilayer sputtering of the DVD-RAM disks.
State of the art in the method of moments

This article presents new developments in the method of moments (MOM). IT describes some variants of this method which deal with general bodies composed of metallic and dielectric structures. Some procedures are presented which combine the method of moments with analytical methods in order to solve additional problem classes in the area of EMC. Two of these approaches are able to analyse the shielding effectiveness (SE) of electromagnetic shields consisting of nonperfectly conductive materials. Both procedures can be implemented by the method of moments. Two other techniques, which are outlined, are able to treat the induction in lines close to metallic surfaces and to analyse the voltages coupled into cables.
Technique for Test Case Selection in Software Maintenance

The main problem of maintaining a program is that the large number of the selected test cases can increase the executing time and maintenance cost. Therefore, the random selection, the data flow technique and a safe regression test are proposed. Unfortunately, the results of the traditional technique cannot satisfy the development team. According to this, the technique for test case selection is proposed. There are 2 main methods used, which are finding the minimum numbers of test cases and selecting the relevant test cases. It can select the smaller size of a test suite when compared with the results from using the traditional techniques. Beside this, it also gives the minimum effects from the new faults, which may occurred during the maintenance process.eywords: Software maintenance, regression test, test suite, test case
Passive and active microvibration control for very high pointing accuracy space systems

This paper presents the results of a two-year proof-of-concept program to prepare for the foreseen needs to master microvibrations on-board high pointing accuracy platforms, through the design, prototyping and experimental validation of four microvibration control systems: (1) an elastomer-based passive isolator for six degree-of-freedom isolation of a disturbance source (reaction wheel or mechanical cooler). Attenuation performance exceeding 20 dB above 25 Hz and 40 dB above 50 Hz has been demonstrated. (2) A passive vibration damping system, based on distributed piezoceramic wafers connected to a dissipative electrical circuit. Such simple, standalone devices are shown to have interesting applications (up 20 dB attenuation) when applied to the damping of a local flexible mode with concentrated strain energy. (3) Active damping with two-dimensional smart structures by using positive position feedback on pairs of collocated piezo-electric wafers used as sensors and actuators. Modal damping from 10 to 20 dB on the best controlled modes has been demonstrated, but some less controllable modes remain essentially undamped. (4) A centralized anti-phase control scheme operating on distributed sensors and actuators to compensate for stationary harmonic disturbances. The sensors are accelerometers and the actuators piezoelectric wafers or active struts equipped with a stack of piezoceramic wafers. The harmonic disturbance (for instance a reaction wheel unbalanced force) is estimated and compensated, with demonstrated attenuation from 30 to 40 dB. Follow-on activities in the domain are focused on the development of flight prototypes of the two active control concepts, for validation through on-orbit experimentation.
Isolation and Development of Efficient Bacterial Consortia for Bioremediation of Textile Dye Effluent

In this study, the ability of bacterial strains isolated from the textile mill site was analyzed for de-colorization of dye effluent. The isolated strains were finally identified by 16S rDNA sequence analysis as Bacillus species and were used for the process of bioremediation. The physicochemical characterization of the effluent generated was also carried out. The effluent was analyzed for its physicochemical properties before and after treatment. Samples were analyzed in UV spectrophotometer and showed the absorption maxima at wavelength of 668 nm. The bacterial strain was found to have sorptive capacity, immobilized on nutrient agar medium. The effluent was treated in a flask containing minimum salt medium, 20% dye effluent and 5% (w/v) of bacterial pellet. The flask was placed in an incubator shaker at 37°C and 200 rpm. After inoculation the sample was analyzed in visible spectrophotometer after every six hours and it was found that 90% de-colorization and 70% reduction in COD was achieved after 24 hours. Heavy metals were also biosorptioned. It was concluded that the isolated bacteria represented a promising application in bioremediation process of textile industrial effluent and possible reusability of the cells for its commercial application can be achieved.
