Influence of WS 2 nanopowder addition on friction characteristics of ta-c coating by FCVA method

The influence of nano-size WS2 powders on the tribological behavior of ta-C coatings by the filtered cathodic vacuum arc (FCVA) method under boundary lubrication conditions has been investigated. In order to characterize and understand tribological behaviors of nano-size WS2 powders added to the synthetic oil (poly-alpha-olefin 6), lubricants with different mixture ratios, ranging from 2 to 8 wt%, have been prepared. ta-C coatings fabricated by FCVA method showed that the G-peak in the obtained Raman spectrum was shifted from 1520 to 1586 cm-1, indicating the sp3 content increased for samples with the thickness of 156 nm. The average friction coefficient decreased proportionally as the nano-size WS2 compositions increased up to 4 wt% in PAO6. After the friction test, structures and particle sizes of WS2 phases were also precisely characterized by using XRD and SEM.
Exploring the possible role of small-scale terrain drag on stable boundary layers over land

This paper addresses the possible role of unresolved terrain drag, relative to the turbulent drag on the development of the stable atmospheric boundary layer over land. Adding a first-order estimate for terrain drag to the turbulent drag appears to provide drag that is similar to the enhanced turbulent drag obtained with the so-called long-tail mixing functions. These functions are currently used in many operational models for weather and climate, although they lack a clear physical basis. Consequently, a simple and practical quasi-empirical parameterization of terrain drag divergence for use in large-scale models is proposed and is tested in a column mode. As an outcome, the cross-isobaric mass flow (a measure for cyclone filling) with the new scheme, using realistic turbulent drag, appears to be equal to what is found with the unphysical long-tail scheme. At the same time, the new scheme produces a much more realistic less-deep boundary layer than is obtained by using the long-tail mixing function.

A Psychophysical Study of Surface Reconstructions Based on Binocular Disparity and Motion Parallax

A visible-surface can be reconstructed either from binocular disparity or motion parallax, and several previous studies have revealed the similarity of the surface properties from either type of reconstruction. In the present research, we have studied the ability for interpolation of reconstructed surfaces, that is, a gap-spanning task was conducted using both static and dynamic random dot patterns which give the same surface perception viewed binocularly and monocularly. We found that: (1) The ability for surface interpolation based on binocular disparity is more effective than that based on motion parallax; and (2) The experimental data correspond to the simulation result of a computational model is based on standard regularization theory. Based on these results, the brain mechanisms of surface reconstruction were discussed.

Relationships between satisfaction of Muslim women on financial supports after divorce and ex-husbands' compliance to the supports with post-divorce welfare

The main objective of this study was to assess the welfare of divorced women in relation to financial supports after divorce, i.e. iddah maintenance, mut’ah, arrears of maintenance, and child maintenance. The specific objectives were to determine the divorced women’s satisfaction with the amount of financial supports, the ex-husbands’ compliance to court-ordered financial supports, their satisfaction with post-divorce welfare (levels of economic strain and depression), the relationships between satisfaction with the amount of financial supports and post-divorce welfare, as well as the relationships between ex-husbands’ compliance to court-ordered financial supports and post-divorce welfare. Data were collected using a questionnaire. The sample comprised of 201 divorced women selected from the cases recorded in the year 2003 till 2005 at the Shariah Subordinate Courts of Hulu Langat and Gombak Timur, Selangor. Pearson correlation showed that two factors were negatively correlated with the economic welfare of the divorced women, i.e. the dissatisfaction with the amount of iddah maintenance, mut’ah, and child maintenance and the ex-husbands’ none or partial compliance to the court-ordered iddah maintenance, mut’ah, and child maintenance. However, on the contrary to the expectation, the divorced women’s satisfaction with the amount of all types of financial supports provided by the ex-husbands and their ex-husbands’ none or partial compliance to all types of financial supports was found to have no significant relationships with depression. The findings also indicated that the assessment of a reasonable sum of financial supports and the effective enforcement of court order were significant factors that might augment the welfare of women after divorce.
A Novel Compensation Based on Pi and Fuzzy Logic Controller for Matrix Converter System with Distorted Input Voltage and Harmonics

Article history: Matrix converter is a single stage converter, which directly connects a three phase supply to a three phase load without dc link. If any harmonic distortion and imbalance in input voltage, it directly reflects to the output of the matrix converter. In this paper two different controller based compensation are discussed to rectify this problem, under distorted input voltage with harmonics of matrix converter and its controlled method are analyzed with PI controller and fuzzy controller based compensation system to prevent effects of distorted input voltage. The proposed method based on the closed loop control of output currents, not only reduces the output harmonic contents but also maintains the load currents. Finally results for the two different compensation systems are discussed and comparison is given for the development.

Quality Costing Practices: A Systematic and Operational Based Framework

Quality is a key competitive weapon in the global marketplace. If it is managed properly, it will not only enhance product differentiation but simultaneously reduce costs. Quality costing has long been promoted as a critical step for the effective planning and implementation of quality improvement programs. The work presented in this research, use empirical data to classify and contextualize the various practices of quality costing. The research uses 23 “best practices” of quality costing extracted from the literature to survey quality managers of 60 publicly listed manufacturing organizations. Exploratory factor analysis is then used to create an empirical framework. Factor analysis of the data identifies a seven-factor structure of the Practices of Quality Costing (PQC). All factors are reliable and valid and have statistically sound structures. The classification provided can help managers to better visualize, understand and implement the concept of quality costing. It provides a framework within which practices can be structured and evaluated; managers can identify areas in their firms that are missing and may warrant improvement. The findings are based on self reported data, collected through a questionnaire. The seven factors identified represent latent constructs within PQC and the component items operationalizing such constructs. Furthermore, the procedure provides an illustration of pragmatic application of exploratory factor analysis to empirical managerial data, which can be used in other contexts.
Exploring Post-Development: Politics, the State and Emancipation. The question of alternatives

This paper explores whether there is any value to post-development. The central argument is that there is if the engagement with Michel Foucault is informed and accurate, and only if post-development can have helpful practical implications. The paper makes a distinction between post-development that is ‘influenced’ by Foucault and the one that stems from a more thorough use of Foucauldian concepts. This distinction has prompted an exploration of post-development theory that shows how an informed Foucauldian treatment of postdevelopment adds value to the analysis and allows for relating post-development concerns to the practice of development. From this foundation it has been possible to identify a number of unanswered questions, but also to demonstrate the potential post-development holds for uncovering possible alternatives to development. Additionally the analysis is revealing to the implications of these alternatives for development practice, but also in relation to politics, emancipation and the State.
Development of nonperturbative nonlinear optics models including effects of high order nonlinearities and of free electron plasma. Part I: Maxwell-Schrödinger equations coupled with evolution equations for polarization effects. Part II: SFA-like nonlinear optics

This paper is dedicated to the exploration of non-conventional nonlinear optics models for intense and short electromagnetic fields propagating in a gas. When an intense field interacts with a gas, usual nonlinear optics models, such as cubic nonlinear Maxwell, wave and Schrödinger equations, derived by perturbation theory may become inaccurate or even irrelevant. As a consequence, and to include in particular the effect of free electrons generated by laser-molecule interaction, several heuristic models, such as UPPE, HOKE models, etc, coupled with Drude-like models [1], [2], were derived. The goal of this paper is to present alternative approaches based on non-heuristic principles. This work is in particular motivated by the on-going debate in the filamentation community, about the effect of high order nonlinearities versus plasma effects due to free electrons, in pulse defocusing occurring in laser filaments [3], [4], [5], [6], [7], [8], [9]. The motivation of our work goes beyond perturbative models, and is more generally related to models of interaction of any external intense and (short) pulse with a gas. In this paper, two different strategies are developed. The first one is based on the derivation of an evolution equation on the polarization, in order to determine the response of the medium (polarization) subject to a short and intense electromagnetic field. Then, we derive a combined semi-heuristic model, based on Lewenstein’s SFA (Strong Field Approximation) model and the usual perturbative modeling in nonlinear optics. The proposed model allows for inclusion of high order nonlinearities as well as free electron plasma effects. We have developed alternative analytical techniques in order to properly include free electron and high order nonlinearity effects in polarization models.
Active RCS Reduction in a Series-fed Dipole Phased Array in Hostile Probing Environment

The radar cross section (RCS) of an aerospace platform can be reduced significantly by controlling the scattering from phased arrays mounted over it. This may be achieved by exploiting the capability of active cancellation of probing sources by the array. If the array reduces the RCS towards the hostile probing directions, the platform becomes invariably invisible towards the probing radar source. This concept of active RCS reduction has been used to reduce the array RCS of a series-fed linear dipole array using modified improved LMS algorithm. The array performance in terms of active RCS reduction depends upon the geometrical configuration, number of antenna elements, design parameters of radiating element and feed network, and the signal environment considered. It is observed that the current feeding parameter does not affect much the adapted RCS pattern; instead parameters like characteristic and load impedances, power level of probing sources and efficiency of adaptive algorithm play crucial role in placing deep nulls in RCS pattern towards the respective probing sources.
Performance and Yield Stability Analysis of Potato Genotypes in Ethiopia

Potato (Solanum tuberosum L.) is one of the most widely grown root and tuber crop in the mid and high altitude areas of Ethiopia. It has both dietary and income generating role to produces. However the yield obtained at farm levels is very low other compared with other county. One of the main reason for such low yield of potato in the country is luck of high yielding and disease resistance variety. To this effect, potato national variety trial was conducted by Adet, Holleta and Kulumsa Agricultural Research Centers with the main objective of identifying high yielder and disease tolerant potato genotypes in 2009 and 2010. In this trial 10 genotypes were tested against standard and local checks in randomized complete block design with three replications on gross plot size of 9 m2 planted at a spacing of 75 cm × 30 cm between rows and plants, respectively. Combined analysis over locations and seasons revealed that the clone CIP-396004.337 gave the highest marketable tuber yield of 345.60 qt/ha followed by CIP-395096.2 (344.20 qt/ha) whereas the lowest tuber yield (156.40 qt/ha) was from CIP-396029.250. Moreover, the lowest percentage (4.03%) of late blight infestation was from CIP-396004.337 as compared to 21.17% from genotype CIP-396029.250. GGE biplot as well as ASV analysis identified CIP-396004.337 as high yielder and stable clone and therefore recommended for release as commercial variety. Since 2013, it is released as new potato variety in Ethiopia with local name of “Dagem”.
EVALUATION OF RESONANCE PROPERTIES OF THE HUMAN BODY MODELS SITUATED IN THE RF FIELD

The radio-frequency (RF) electromagnetic field absorption in the human body model is investigated in this article. Absorption of prolate model of the biological body exhibits resonance properties in the case of so called E polarization. This occurs in the arrangement when the longitudinal axis of the body is parallel with an electrical component of the electromagnetic field. Absorption properties of a homogeneous human model have been explored in the frequency range from 20 MHz to 500 MHz in the CST Microwave Studio programme environment. The simulation results of RF field absorption in the model of the human body are presented for ellipsoidal, cylindrical and anthropomorphic Laura model shapes, and for various heights and widths of the model body. The values of the resonance frequency and also whole-body absorption values at these frequencies are evaluated.
Special, conjugate and complete scale functions for spectrally negative Lévy processes

Following from recent developments in Hubalek and Kyprianou [28], the objective of this paper is to provide further methods for constructing new families of scale functions for spectrally negative Levy processes which are completely explicit. This is the result of an observation in the aforementioned paper which permits feeding the theory of Bernstein functions directly into the Wiener-Hopf factorization for spectrally negative Levy processes. Many new, concrete examples of scale functions are offered although the methodology in principle delivers still more explicit examples than those listed.
Resistance to Pyrenophora teres f. teres and P. teres f. maculata in Canadian Barley Genotypes

The fungi Pyrenophora teres Drechs. f. teres Smedeg. (Ptt) and Pyrenophora teres Drechs. f. maculata Smedeg. (Ptm) cause the net (NFNB) and spot forms (SFNB) of net blotch of barley (Hordeum vulgare L.). The reaction of a collection of barley genotypes previously identified as resistant to NFNB and/or SFNB in western Canada was assessed against seven isolates each of Ptt and Ptm. These included isolates recently collected from western Canada plus reference isolates frequently used in resistance breeding programs. Experiments were conducted under greenhouse conditions, with the second and third leaves of each plant rated on disease reaction scales of 1 to 10 (Ptt) or 1 to 9 (Ptm) 1 wk after inoculation. The NFNB resistance in the cultivars ‘Vivar’ and ‘CDC Helgason’ was overcome by two and four of the Ptt isolates, respectively. ‘AAC Synergy’ was resistant to all Ptt isolates examined, although two caused disease severities of 4.6 and 5.0, suggesting some adaptation to the resistance in this cultivar. The breeding lines Tr 253, CI 9819, and Tr 236 were the most resistant to Ptt, with average disease severities of almost 3.0. resistance to SFNB in ‘CDC Meredith’ was overcome by all Ptm isolates tested, while ‘Cerveza’, ‘Major’, and AAC Synergy were resistant to all of the isolates. Among the breeding lines, Tr 236 was the most resistant to Ptm, with an average rating score of 3.9. The identification of isolates virulent on cultivars classified as “resistant” highlights the need for integrated disease management approaches to avoid net blotch resistance breakdown in western Canada.

Occurrence of Bacterial Stem Rot of Ranunculus asiaticus Caused by Pseudomonas marginalis in Korea

In December 2016, stem rot symptoms were observed on Persian buttercup (Ranunculus asiaticus) plants in Chilgok, Gyeongbuk, Korea. In the early stage of the disease, several black spots appeared on the stem of infected plants. As the disease progressed, the infected stem cleaved and wilted. The causal agent was isolated from a lesion and incubated on Reasoner’s 2A (R2A) agar at 25°C. Total genomic DNA was extracted for phylogenetic analysis. Based on the 16S rRNA gene analysis, the isolated strain was found to belong to the genus Pseudomonas. To identify the isolated bacterial strain at the species level, the nucleotide sequences of the gyrase B (gyrB) and RNA polymerase D (rpoD) genes were obtained and compared with the sequences in the GenBank database. As the result, the causal agent of the stem rot disease was identified as Pseudomonas marginalis. To determine the pathogenicity of the isolated bacterial strain, it was inoculated into the stem of healthy R. asiaticus plant, the inoculated plant showed a lesion with the same characteristics as the naturally infected plant. Based on these results, this is the first report of bacterial stem rot on R. asiaticus caused by P. marginalis in Korea.

Risk and Uncertainty in Anesthesia

This article discusses risk and uncertainty, both stochastic and epistemic, as it applies to anesthesia. It shows the difficulty in quantifying risk of individual case and the somewhat arbitrary and even incorrect and naive assignment of risk in individual patient care management. Effective and honest communication remains at the core of physician-patient relationship in discussing, evaluating and managing the individual case for optimum outcome as well as patients’ and their families' satisfaction and understanding.
