GA – A 23892 RESISTIVE WALL MODE CONTROL ON THE DIII – D DEVICE by

External kink modes have been identified as one of the major obstacles to achieving high pressure plasmas in toroidal devices. From the beginning of fusion research, it has been well known that a conducting shell can improve the stability if the shell is ideal. A shell with finite resistivity can still stabilize the fast growing ideal magnetohydrodynamic (MHD) mode, however, the external kink mode is converted into the resistive wall mode (RWM) branch, which grows with the shell skin time constant. On the DIII-D device, two schemes have been explored to stabilize the slowly-growing resistive wall mode: one using magnetic feedback and the other utilizing rapid plasma rotation. Recent RWM experiments have revealed that these two schemes are strongly coupled in a synergetic manner and that the stabilization operation functions as a unified scheme. It was found that the magnetic feedback operation can track the residual error field which excites the stable resistive wall mode near the marginally stable condition (Error Field Amplification). The magnetic field applied through the feedback process can reduce the mode amplitude, compensate the error field, and simultaneously maintain the plasma rotation. As a consequence of the higher plasma rotation, a stable path opens up to the ideal-wall limit. Discharges with beta up to twice the no-wall beta limit have been achieved. Experimental observations and stability calculations indicate that these discharges are at the ideal wall kink limit.
Stability Analysis of an SEIRModel with Treatment

We study the dynamics of a SEIR epidemic model with nonlinear treatment function, that takes into account the limited availability of resources in community. Under some conditions we prove the existence of two possible equilibria: the disease-free equilibrium and the endemic equilibrium. Using Lyapunov’s method and Li’s geometrical approach, We also show that the reproduction number R0 is a threshold parameter: the disease-free equilibrium is globally asymptotically stable when the basic reproduction number is less than unity and the unique endemic equilibrium is globally asymptotically stable when the basic reproduction number is greater than this critical value. In the end, we give some concluding remarks concerning the role of treatment on the epidemic propagation.
Factors Affecting Dividend Policyin an Emerging Capital Markets (ECM’s) Country: Theoratical and Empirical Study

The dividend decision is taken after careful consideration of a number of factors, such as legal and financial. This is because it is impossible to develop a dividend policy set that applies to all companies. The decision about dividends differs from company to company in the light of company considerations. The dividend is partly dependent on the current earning of the company and partly on the dividend from the previous year. Therefore, the main changes in profit with the existing rate of dividends were the main determinants of corporate dividend policy. The research showed that the profitability aspects and their indicators for each of the return on equity return on asset, and earning per share without dividend yield, have the greatest impact on share price performance, followed by the financial risks aspect of financial leverage without gains variation which comes in the second rank. Then, the factor of size, investment opportunity for each of investment opportunity and net profit standard deviation without assets volume comes in the third place and finally, the liquidity and signals factor represented in the cash ratio without signals index. While the profitability aspects and its indicators for each of the return on equity, return on asset, earning per share without dividend yield are the most effective on pay-out ratio (first rank), followed by financial risks aspect and gains variation coefficient without financial leverage in the second rank, then the liquidity factor of index without the signals in the third place and finally size and investment opportunity factor for each of investment opportunity and assets volume without net profit standard deviation.
Impact of short term vocational training on youth unemployment : Evidence from Mongolia working paper 2017-12 March 2017

Mongolia is a lower-middle income country characterized by high youth unemployment and a large informal sector. Training programs have been implemented in order to promote employment and tackle these issues. In this study, we evaluate the impact of a vocational training program (VTP) through a field experiment conducted between 2013 and 2015. This time frame allows us to explore short and medium term impacts. In particular, we focus on three outcomes of interest: employment, earnings and job quality. We find a positive and short-term impact on employment and a positive impact on monthly earnings in short and medium terms. We also show that providing information about schooling returns increases attendance and reduces dropout, which may help improve the program’s impact in nonexpensive ways. Keyword: vocational training programs, labor market, randomized controlled trial, employment, earnings, job quality.

Volatility spillovers and other market dynamics between cryptocurrencies and the equity market

Little is known about the market dynamics between the conventional equity market and cryptocurrencies, whilst such insights become increasingly important with the recent introduction of financial derivatives related to these coins. This study covers four well known phenomena in a bivariate setting, combining two stock indices (S&P500 and Nikkei 225) with five cryptocurrencies (Bitcoin, DASH, Litecoin, Monero, and Ripple), resulting in a number of new insights. Firstly, convincing evidence is found that the volatility of cryptocurrencies is highly affected by the dynamics of the equity market, whereas a vice versa effect is not present. Secondly, the findings provide no evidence for the presence of a traditional leverage effect in the returns of cryptocurrencies. Thirdly, the time varying correlation between the equity market and the cryptocurrencies approximates zero on average and is heavily affected by the volatility of both assets, whereas the correlation between Bitcoin and its peers is considerably higher and mainly event driven. Lastly, the past returns of both stock indices and the Bitcoin negatively impact the current returns of the (other) coins, while the effect in opposite direction is only marginal. However, this (cross) return predictability proved to increase substantially over longer horizons. JEL classification: C32; C51; C58; G11; G14; G17; G41.
Environmental Impact of Cow Milk Production in the Central Italian Alps Using Life Cycle Assessment

The aim of the study was to analyze environmental impact of cow milk production in an alpine area through a cradle-to-farm-gate Life Cycle Assessment and to identify farming strategies that can improve environmental sustainability without negatively affecting profitability. Data were collected from farmers in 28 dairy farms in an Italian alpine valley. The production of 1 kg of fat protein corrected milk (FPCM) needed 3.18 m2 of land; land use on-farm was high because a large part of farm land consisted of pastures in the highland, used extensively during summer. Also the use of energy from non-renewable sources was high, 5.14 MJ kg FPCM-1 on average. Diesel for production and transportation of feed purchased off-farm was mainly used, especially concentrates which were entirely purchased. The average emission of greenhouse and acidification causing gases was 1.14 kg CO2-eq and 0.021 kg SO2-eq kg FPCM-1. Eutrophication was on average 0.077 kg of nitrate-eq kg FPCM-1. Farms with low producing cows had higher environmental impact per kg of milk and lower gross margin per cow compared to the others. Low stocking rate farms had the best results regarding acidification and eutrophication per kg FPCM. Farms with high feed self-sufficiency had significantly lower acidification potential than the others. Increasing milk yield per cow, by selection and feeding, and enhancing feed self-sufficiency, by higher forage production and quality and more exploitation of highland pastures, seem to be the best strategies to improve ecological performances of dairy farms in the Alps while maintaining their profitability.
Becoming Salient: The TMT Leader’s Role in Shaping the Interpretive Context of Paradoxical Tensions

How do paradoxical tensions become salient in organizations over time? Ambidexterity and paradox studies have, thus far, primarily focused on how tensions inside organizations are managed after they have been rendered salient for actors. Using a longitudinal, embedded case study of four strategic business units within a media organization, we theorize the role of the top management team leader’s practices in enabling tensions to become salient for their respective lower-level managers when there are initial differences in how tensions are interpreted across levels. Our findings extend a dynamic equilibrium model of organizing by adding interpretive context as an enabling condition that shapes the emergence of salience through the provision of a constellation of cues that guide sensemaking. Informed by a practice-based perspective on paradox, we also contribute a conceptual model of leadership as practice, and outline the implications for ambidexterity studies.
Effect of Foliar Application with Calcium , Potassium and Zinc Treatments on Yield and Fruit Quality of Washington Navel Orange Trees

Yield and fruit quality of Washington navel orange trees in response to spraying both calcium chloride and zinc sulphate at 0.5, 1 and 1.5% and potassium sulphate at 1, 2 and 3% were evaluated during two successive seasons, 2013 and 2014 at Abou–EL Matamier, Beheira Governorate, Egypt. The experiments were designed as randomized complete block design with five replications. Results showed that all treatments were very effective in improving yield as well as average fruit weight (g), average fruit volume (cm), average fruit diameter (cm), average fruit length (cm), vitamin C and TSS (%) rather than control. Also, the used treatments led to significant decreases in the juice acidity percentage compared to the control treatment. The best results with regard to yield and fruit quality were significantly obtained due to spraying Washington navel orange trees with 2 and 3% potassium sulphate treatments.
Effects of thermal processing on physicochemical properties and oxidative stability of Balanities aegyptiaca kernels and extracted oil

In the present study, the effects of roasting and boiling on the proximate composition of the kernels as well as the physicochemical properties and oxidative stabilities of the extracted oils of Balanites aegyptiaca were investigated. Roasting was performed at 180 ˚C for 15 minutes, whereas boiling of the kernels was carried out in tap water for one hour. The oils from raw and thermally processed samples were extracted using n-hexane in a Soxhlet extraction apparatus and characterized. The roasting significantly (p < 0.05) influenced the peroxide value and the oxidative stability of the extracted oil in a positive way; whereas boiling had the opposite effect. The oils were composed of linoleic, oleic, stearic, and palmitic acids as the major fatty acids (96%) and contained predominantly α- and γ-tocopherols (ca. 400mg/kg). The study suggests that the oil from roasted kernels could be used as a natural antioxidant for enhancing the characteristics of other edible oils via blending.
Analysis of Stochastic Reserving Models By Means of NAIC Claims Data

In the past two decades increasing computational power resulted in the development of more advanced claims reserving techniques, allowing the stochastic branch to overcome the deterministic methods, resulting in forecasts of enhanced quality. Hence, not only point estimates, but predictive distributions can be generated in order to forecast future claim amounts. The significant expansion in the variety of models requires the validation of these methods and the creation of supporting techniques for appropriate decision making. The present article compares and validates several existing and self-developed stochastic methods on actual data applying comparison measures in an algorithmic manner.
Preferred ‘learning styles’ in students studying sports‐related programmes in higher education in the United Kingdom

This article investigates the ‘preferred learning styles’ and their relationship with grades for students undertaking sports‐related undergraduate programmes at a higher education institution in the UK. Preferred ‘learning styles’ in students in this discipline have been identified as auditory, kinaesthetic and group, although the vast majority of students are multimodal in their learning preferences. Only individual learning style preference was found to be positively related to higher grade category, and group learning style preference was negatively related to grade category. The research aims to highlight the importance of a constructive alignment between sports learning activities and the learning styles of sports students, in order to enhance progression towards established sports learning outcomes. An issue of significance for the practitioner would be rebalancing learning and teaching methods to take cognisance of particular preferred learning styles, while still seeking to ensure that all learning styles are supported.
Herd dynamics and productivity performance modeling of livestock in smallholder crop-livestock systems in Southwestern Ethiopia

This study aimed to examine herd dynamics relatively in wider array in two different administrative zones to model scope of improving productivity performance of ruminant livestock by management optimization using existing modeling tools. In implication, herd demographic parameters gathered at household level has modeled by management optimization in existing PRY herd modeling tools for ruminant livestock productivity assessment. The differences observed in both descriptive analysis and the model prediction in the study could be of the demographic, reproductive, productive or sizable combined effect of these factors that resulted in livestock phenotypical value and household income. Intensified feeding strategies from existing sources, improvement through rearing and herd management viewed to make potential improvement in livestock production and could re-integrate the strategies of the livelihood in smallholder mixed system. Where variability assessment in herd demographic parameters could an opportunity suit livestock intensification interest to support the sustainable development of the rural poor.
MAPPING THE MONOCEROS RING IN 3D WITH PAN-STARRS1

Using the Pan-STARRS1 survey, we derive limiting magnitude, spatial completeness, and density maps that we use to probe the three-dimensional structure and estimate the stellar mass of the so-called Monoceros Ring. The Monoceros Ring is an enormous and complex stellar sub-structure in the outer Milky Way disk. It is most visible across the large Galactic Anticenter region, , . We estimate its stellar mass density profile along every line of sight in 2° × 2° pixels over the entire 30,000 deg2 Pan-STARRS1 survey using the previously developed match software. By parsing this distribution into a radially smooth component and the Monoceros Ring, we obtain its mass and distance from the Sun along each relevant line of sight. The Monoceros Ring is significantly closer to us in the south (6 kpc) than in the north (9 kpc). We also create 2D cross-sections parallel to the Galactic plane that show 135° of the Monoceros Ring in the south and 170° of the Monoceros Ring in the north. We show that the northern and southern structures are also roughly concentric circles, suggesting that they may be waves rippling from a common origin. Excluding the Galactic plane , we observe an excess mass of across . If we interpolate across the Galactic plane, we estimate that this region contains . If we assume (somewhat boldly) that the Monoceros Ring is a set of two Galactocentric rings, its total mass is . Finally, if we assume that it is a set of two circles centered at a point 4 kpc from the Galactic center in the anti-central direction, as our data suggests, we estimate its mass to be .

PLANT LONGCHAIN ISOPRENOID ALCOHOLS POLYPRENOLS PROTECT LIVER VIA STABILISATION OF CELL MEMBRANES AND ORGANELLE STRUCTURE IN A CARBON TETRACHLORIDE ANIMAL MODEL OF TOXIC LIVER DAMAGE

The mechanism for the ability of pharmaceutical-grade plant long-chain isoprenoid alcohols (polyprenols) to improve liver function was investigated in a carbon tetrachloride animal model of liver damage. The pharmaceutical-grade polyprenol substance, Ropren®, was compared with a commonly used phospholipid substance, Essentiale Forte, for 21 days of treatment. The condition of hepatic cells and cellular membranes was investigated using electron and light microscopy. The study showed Ropren® restored liver function and morphology as soon as day 7–14 of treatment, an eff ect that was faster than improvement after treatment with Essentiale Forte. Similarly, levels of glycogen in the liver were restored faster after treatment with Ropren® than Essential Forte. Measurement of the activity of the membrane-bound enzymes, monoamine oxidase (MAO) and butyrylcholinesterase (BuChE) also showed Ropren® improved liver function by improving cellular membrane and mitochondrial membrane function. To our knowledge, these results show for the fi rst time a mechanism of the stabilisation of cellular membranes after treatment with Ropren® along with improvements in liver enzymes. These functional improvements occur faster than Essentiale Forte, a commonly used hepatoprotector.

Low power current sources for bioimpedance measurements: a comparison between Howland and OTA-based CMOS circuits

Abstract Multifrequency Electrical Bioimpedance (MEB) has been widely used as a non-invasive technique for characterizing tissues. Most MEB systems use wideband current sources for injecting current and instrumentation amplifiers for measuring the resultant potential difference. To be viable current sources should have intrinsically high output impedance for a very wide frequency range. Most contemporary current sources in MEB systems are based on the Howland circuit. The objective of this work is to compare the Mirrored Modified Howland Current Source (MMHCS) with three Operational Transconductance Amplifier (OTA) based voltage controlled current sources (i.e., class-A, class-AB and current conveyor). The results show that both current conveyor and class-AB OTA-based current sources have a wider output current frequency response and an output impedance of 226% larger than the MMHCS circuit at 1 MHz. The presented class-AB OTA circuit has a power consumption of 4.6 mW whereas current conveyor consumed 1.6 mW. However, the MMHCS circuit had a maximum total harmonic distortion of 0.5% over the input voltage from -0.5 to +0.5 V. The OTA-based current sources are going to be integrated in a semiconductor process. The results might be useful for cell impedance measurements and for very low power bioimpedance applications.

A Hybrid Approach of Hyper Spectral Image Restoration and Quality Assessment

Haze is an atmospheric phenomenon that significantly degrades the visibility of outdoor scenes. This is mainly due to the atmosphere particles that absorb and scatter the light. This paper introduces a novel single image approach that enhances the visibility of such degraded images. Our method is a fusion-based strategy that derives from two original hazy image inputs by applying a white balance and a contrast enhancing procedure. To blend effectively the information of the derived inputs to preserve the regions with good visibility, we filter their important features by computing three measures (weight maps): luminance, chromaticity, and saliency. To minimize artifacts introduced by the weight maps, our approach is designed in a multiscale fashion, using a Laplacian pyramid representation. We are the first to demonstrate the utility and effectiveness of a fusion-based technique for dehazing based on a single degraded image. The method performs in a perpixel fashion, which is straightforward to implement. The experimental results demonstrate that the method yields results comparative to and even better than the more complex state-of-the-art techniques, having the advantage of being appropriate for real-time applications.
