DOES SEED TREATMENT WITH GLYCINEBETAINE IMPROVE GERMINATION RATE AND SEEDLING GROWTH OF SUNFLOWER (HELIANTHUS ANNUUS L.) UNDER OSMOTIC STRESS

Sunflower (Helianthus annuus L.) cv Suncross and Gulshan-98 achenes were germinated in Petri-plates containing filer papers moistened with solution of polyethylene glycol, PEG-8000 (control and osmotic potential -0.6, -1.2 MPa) with and without glycinebetain (GB) application (0, 25 and 50 mM). PEG treatment severely reduced germination percentage and fresh and dry biomass and mean germination time (days to 50% germination) in both sunflower cultivars. Addition of GB in growth medium was not effective in alleviating the adverse effects of osmotic stress on germination percentage, mean germination time and seedling dry biomass. In contrast, a slight increase in seedling fresh biomass was observed by the application of 25 mM GB under control and osmotic stress.

Ensuring Fair-deal Service in Multi-core Processor Environment

Present day multi-core processors integrate dozens of small processing cores with an on-chip network consisting of point-to-point links. The network enables communication between the processing cores and sharing of common resources such as memory and I/O controllers. In this work, we propose an arbitration scheme to ensure fair-deal service in accessing a chip’s shared resources by eliminating any bias in accessing a shared resource by a core based on its location in the multi-core chip. We propose using probabilistic arbitration combined with distance-based weights to achieve fair-deal service and overcome the limitation of conventional round-robin arbiter. We describe how nonlinear weights need to be used with probabilistic arbiters and propose three different arbitration weight metrics – constant weight, linearly increasing weight, and randomly increasing weight. By simply changing the arbitration of an on-chip router, we can create a simple, low-cost mechanism for achieving fair-deal service without requiring any additional buffers or virtual channels. We evaluate our arbitration scheme across a wide range of traffic patterns. In addition to providing fair-deal service, the proposed arbitration has additional benefits such as providing enhanced throughput, reduced latency, thus, providing a more stable network.
Effects of Probiotic Additions to Feed and Manure on Temperature, Humidity, and Carbon Dioxide Emissions in Hanwoo Manure during Summer - A Field Study

Abstract The effects of probiotic additions to feed and manure on temperature, humidity and carbon dioxide (CO 2 ) emissions in Hanwoo manure during summer (4 weeks) were evaluated. Fifteen Hanwoo (24-mo-old, 580 ± 20 kg) were housed in individual pens (5 × 8 m) and randomly assigned to 1 of 3 treatments (n = 5 cattle per treatment). Hanwoo were fed experimental rations as follows: control (10 kg roughage + 2 kg concentrate); T1 (10 kg roughage + 2 kg concentrate, 2% probiotics on as-fed basis); and T2 (10 kg roughage + 2 kg concentrate, 2% probiotics on as-fed basis + 7 kg probiotics as top-dressing on the surface of Hanwoo manure). In comparison to the control, the addition of probiotics to feed or feed and manure had an effect (P < 0.05) on temperature and humidity over the 4 weeks, except for humidity at 0 weeks. The only significant difference (P < 0.05) observed in CO 2 emission was among all treatments at 3 and 4 weeks (but not at 0 through 2 weeks). These results indicated that use of probiotics as feed and manure additives did not have a significant effect on environmental parameters.
Partial discharge activity in oil - paper insulated system under DC superimposed AC and harmonic voltage

In the present study, the partial-discharge activity under nonstandard voltage formed by ac, harmonic, and dc voltages was studied. It is identified that the negative dc voltage superposed with ac and high frequency harmonic enhances the discharge activity in the medium and if the negative dc voltage is superposed with ac and low frequency harmonic, it can mitigate the discharge activity. The signal of the partial discharges in oil-paper insulated systems under the composite voltage formed by dc superposed with ac and harmonic voltages, has a dominant frequency content at around 20 MHz.

What Determines The Capital Structure Of Listed Firms In Romania

This paper examines the relative importance of four factors in the capital structure decisions of Romanian listed firms. The existing empirical research on capital structure has been largely confined to developed countries. The Romanian Financial Market has been developing at an exponential rate and dedicated research in the field is required. We used 100 firms listed in 2010 at the Bucharest Stock Exchange. The objective of this paper is to build on previous studies model all the important factors affecting capital structure decisions. We find that factors such as tangibility of assets, firm size, liquidity, and profitability have significant influences on the leverage structure chosen by firms. These results are believed to have significant implications for the theory of finance and to be of importance to the corporate treasure in choice of new financing and to the financial analyst.
Resolving the Unfairness Limitations of the IEEE 802.11 DCF

In this paper, we propose a new solution to cope with the unfairness limitations of the Distributed Coordination Function (DCF) algorithm. Indeed, in current widely deployed IEEE 802.11b wireless local area networks (WLAN), the performance of all the competing access nodes are dramatically affected once the bit rate of one station degrades. This anomaly is due to the unfairness behavior of the DCF algorithm. To avoid this, our solution is based on multiple backoff windows principle. We demonstrate through simulations the efficiency of our proposal. Our results show that the proposed algorithm enables fair bandwidth sharing and increases significantly the total network throughput.
Werkstraffen: succes verzekerd? Succes- en faalfactoren bij werkstraffen van meerderjarigen.

Dit is een verslag van een onderzoek naar het verbeteren van de uitvoering van werkstraffen die aan volwassenen worden opgelegd of aangeboden. De bedoeling is het verhogen van het aantal succesvol afgeronde werkstraffen en een strafrechtelijk vervolg geven aan mislukte werkstraffen. Daarbij wordt een onderscheid gemaakt naar drie groepen werkgestraften. - Werkgestraften die niet starten met de werkstraf; - Werkgestraften die wel een intakegespreke hebben gehad, maar de werkstraf niet hebben voltood; - Werkgestraften die de werkstraf daadwerkelijk hebben afgerond (voltooid).
Drivers of customer equity

The ‘service revolution’ has shifted the core of exchange between firms and customers from products to the provision of service (Vargo and Lusch, 2004). Longterm onetoone customer relationships have come to the fore while customer transactions, the hallmark of a product economy, are being increasingly deemphasized (Peppers and Rogers, 1993). While firms can’t ignore the need for attracting new customers, the retention of existing customers has become more crucial to longterm profitability. Innovations in information technology further accelerate such structural changes in the economy as true interactivity between firms and customers, customer specific personalization, and realtime adjustments to a firm’s offerings are becoming reality (Rust and Lemon, 2001). Such trends that define today’s economy necessitate the fundamental rethinking of business and strategy around the customer. The notion that customer assets are becoming more and more important is not new. For example, Procter & Gamble renamed its sales department as ‘Customer Business Development’ more than a decade ago to integrate such thinking into its operations (Sheth and Parvatiyar, 2002). However, the increasing pace of economic and technological change forces firms to move beyond simply recognizing that the customer lies at the heart of business – to evolve into truly customercentric companies (Rust, Zeithaml, and Lemon, 2000, 2004). This calls for marketing, and potentially the entire firm, to organize and deploy all tangible and intangible assets into maximizing customer equity. Customer equity should lie at the heart of any firm’s philosophy and vision. The decision criterion for all business functions and operations should be whether an action contributes to growing customer equity. In this chapter we lay the groundwork for firms to adapt to become true customercentered companies by providing an overview of the drivers of customer equity and introducing a method for implementing a customer equity program.
Detection of high frequency magnetic signature for large electrical machines: a monitoring tool

The turn-to-turn insulation quality of electrical machines can be monitored using high frequency resonance detection in windings. Indeed, for standard turn insulation made of polyester-imide and polyamide-imide coating, the polymer aging causes a slight increase of the turn-to-turn capacitance therefore a slight change of several winding resonance frequencies. Such change can be detected by an appropriate monitoring system. For large machines, the interesting spectrum is in the range 10MHz -50MHz. The paper describes a method based on magnetic field measurements able to detect such resonance frequencies for large machines. Streszczenie. Jakośc izolacji wokol cewek maszyn elektrycznych moze byc monitorowana stosując metode detekcji rezonansem wysokoczestotliwościowym. Rzeczywiście, dla standardowej izolacji zwoju wykonanej z poliestroamidu i pokrytego poliamidowa powloką, starzenie powoduje niewielki wzrost pojemności miedzyzwojowej dla roznych czestotliwości rezonansowych. Taka zmiana moze byc wykryta za pomocą odpowiedniego systemu monitoringu. W przypadku duzych maszyn, ciekawe spektrum wystepuje w zakresie 10MHz-50MHz.

Prototyping of an HV-CMOS demonstrator for the High Luminosity-LHC upgrade

HV-CMOS sensors can offer important advantages in terms of material budget, granularity and cost for large area tracking systems in high energy physics experiments. This article presents the design and simulated results of an HV-CMOS pixel demonstrator for the High Luminosity-LHC. The pixel demonstrator has been designed in the 0.35 μm HV-CMOS process from ams AG and submitted for fabrication through an engineering run. To improve the response of the sensor, different wafers with moderate to high substrate resistivities are used to fabricate the design. The prototype consists of four large analog and standalone matrices with several pixel flavours, which are all compatible for readout with the FE-I4 ASIC. Details about the matrices and the pixel flavours are provided in this article.
WHY DO PEOPLE KEEP THEIR PROMISES? AN EXPERIMENTAL TEST OF TWO EXPLANATIONS

Numerous psychological and economic experiments have shown that the exchange of promises greatly enhances cooperative behavior in experimental games. This paper seeks to test two theories to explain this effect. The first posits that individuals have a preference for keeping their word. The second assumes that people dislike letting down others' payoff expectations. According to the latter account, promises affect behavior only indirectly, because they lead to changes in the payoff expectations attributed to others. I conduct an experiment designed to distinguish between and test these alternative explanations. The results demonstrate that the effects of promises cannot be accounted for by changes in payoff expectations. This suggests that people have a preference for promise keeping per se.

TOWARDS IMPLEMENTATION AND AUTONOMOUS NAVIGATION OF AN INTELLIGENT AUTOMATED GUIDED VEHICLE IN MATERIAL HANDLING SYSTEMS

Automated Guided Vehicles (AGV) have been a conventional solution and choice made by many manufacturing enterprises as means for Flexible Material Handling Systems (FMHS). In recent years, a considerable number of these vehicles have been installed on shop floors worldwide, effectively proving the usefulness of material handling systems. However, the increasing complexity of demand as well as a need for “make to order” rather than “make to stock” policy implies usage of more intelligent material handling solutions. This paper discusses the usage of an intelligent AGV as means for FMHS which should have Intelligent Material Handling System (IMHS) as the final outcome. This paper presents the experimental results of hybrid robotic control architecture. To evaluate the performance of the architecture, a mobile robot built on LEGO Mindstorms NXT technology was used. Some of the architectural modules are based on the implementation of Artificial Neural Networks in order to achieve the needed robustness in exploitation. Then, through simulation using AnyLogic 6 software, the performance in terms of manufacturing system effectiveness and workstation utilization is analyzed. Based on the experimental results, the proposed IMHS can have significant advantages over conventional material handling systems. Keywords– Flexible material handling system, intelligent automated guided vehicle, artificial neural networks, discrete event simulation
Viscoelastic Boundary Conditions for Multiple Excitation Sources in the Time Domain

Transmitting boundaries are important for modeling the wave propagation in the finite element analysis of dynamic foundation problems. In this study, viscoelastic boundaries for multiple seismic waves or excitations sources were derived for two-dimensional and three-dimensional conditions in the time domain, which were proved to be solid by finite element models. Then, the method for equivalent forces’ input of seismic waves was also described when the proposed artificial boundaries were applied. Comparisons between numerical calculations and analytical results validate this seismic excitation input method. The seismic response of subway station under different seismic loads input methods indicates that asymmetric input seismic loads would cause different deformations from the symmetric input seismic loads, and whether it would increase or decrease the seismic response depends on the parameters of the specific structure and surrounding soil.
Monotone optimal policies for quasivariational inequalities arising in optimal portfolio liquidation

This thesis studies the Hamilton-Jacobi-Ballman quasivariational inequality (HJBQVI), the corresponding optimal value function, and discrete schemes useful for approximating this value function. Moreover, the structural properties of the optimal policy of particular discrete scheme is studied. The motivation is to find a convergent, approximating scheme for the otherwise complicated HJBQVI that has monotone policy structure that can be exploited in a stochastic gradient estimation scheme to approximate optimal policy function parameters. In order to motivate this approach, we consider the problem of optimal liquidation of a single risky asset portfolio as an impulse control problem. The model is defined over continuous time, state, and compact action sets, and the optimal liquidation value and strategy are found from the viscosity solution of a HJBQVI. It is shown that the optimal strategy is monotone in the number of shares owned and the time remaining to liquidation. This structural result is exploited to estimate the optimal policy via a reinforcement learning method based on the simultaneous perturbation stochastic approximation (SPSA) algorithm. The optimal policy can be estimated without knowledge of the parameters of the underlying model.
Are Micrornas the Answer to Colorectal Cancer's Big Questions?

The question, “What determines whether a polyp will become cancerous? ” was recently declared one of the five central puzzles critical to advancing colon cancer treatment [1]. The benign to cancerous transition is a critical intervention stage as tumors diagnosed in subsequent non-localized and malignant stages are exponentially more difficult to treat successfully. The decreasing mortality rate is largely credited to increased screening with sigmoidoscopy, colonoscopy, and fecal occult blood tests that result in early detection of precancerous polyps or early stage colon cancer. Despite the increased preventive screening, colorectal cancer remains a deadly disease, with an estimated 136,830 new cases and 50,310 deaths in the United States in 2014 [2]. There is both a critical need and opportunity for novel treatment strategies that either halt or prevent the transformation from polyp to cancer.
Stability of Spot price and Futures market for Agricultural commodity: based on the sugar products

The mechanism of the stability of spot price will be further analyzed on the basis of ARMA-GARCH model, selecting the daily data of the spot price and the futures price of sugar products. However, as the new factors appeared, it is inappropriate to analyze by GARCH model with dummy variable. Thus, the paper also establish the GARCH model with futures trading volume to verify the spot price stability function of the futures market and test the robustness of the model. The results show that the spot prices tend to be stable with the improvement of agricultural futures market, but different agricultural futures market are not the same. The futures market of agricultural products is the earliest futures market in China, concerning soybean, corn, wheat, sugar and cotton. With the accession to the world trade organization, the Zhengzhou Futures Trading opened sugar futures market in January, 2006, aiming to provide a place to hedge sugar productions. However, in 2014, Zhengzhou Commodity Exchange of sugar futures prices fell sharply and rose sharply then. As the result, manufacturers has sold spots for the withdrawal from circulation of funds and faced the destruction. In fact, the agricultural products futures market is originally designed to promote the sound development of the spot market . However, some scholars held that the futures price of agricultural products and the spot market is separated, and the futures market is not conducive to price stability. Therefore, the objective of this study is to explore the real association between the futures market and the spot price stability. Using a sample of sugar and cotton futures as representations and the daily trading volume as a proxy for the quantity of the futures market variable, we show that spot prices tend to be stable with the establishment and improvement of agricultural futures market. The paper is organized as follows. Section I provides literature review and theoretical motivation for the empirical analysis. Section II describes the data and Section III discusses the empirical results and robustness tests. Concluding remarks are contained in Section IV.
Mediated Learning Interactions in Adult asic Education : Instructors ' Responses to Students ' Needs

A study investigated instructors' responses to learners' needs from the perspective of Feuerstein's Mediated Learning Experience (MLE) theory. Participants were 53 adult educators enrolled in an adult education course at Auburn University. Four scenarios were constructed, each based on one of the five MLE criteria (intentionality, meaning, transcendence, competence, and task regulation). In each situation that depicted adults experiencing learning difficulties, participants were asked to select from five choices the solution they would normally offer students. The choices represented a range of teacher behaviors from noninteractive to highly mediating. A general question was included with each scenario that was aimed at investigating the fifth MLE criterion, feelings of competence. Instructors indicated how they would promote feelings of competence, with choices ranging from nonmediating to highly mediating. Two patterns of responses were found: instructors were either mediating or directing in terms of their intent to facilitate learning and of helping students transfer their learning beyond the particular setting and task at hand, and they were mediating in their approaches to influencing how the meaning and importance of information is perceived and in supporting the use and regulation of strategies in learning tasks.

Comparison of the Therapeutic Effects Recombinant Human Acidic and Basic Fibroblast Growth Factors in Wound Healing in Diabetic Patients

To explore an optimal improvement of diabetic wound healing we have comparatively studied the effects of recombinant human acidic and basic fibroblast growth factors (rhaFGF and rhbFGF) on the healing impaired skin wounds in diabetic patients. Before using rhaFGF in diabetic patients, its pharmacokinetic features and possible toxic effects were evaluated using a rabbit model. For the 139 diabetic patients, 25% of them were divided into the group to receive topical rhbFGF daily at the dose of 100 U/0.1 ml/cm2 as positive control (n=35), and the remainder to receive topical rhaFGF at the same dose as rhbFGF (n=104). Pharmacokinetic studies showed that plasma concentration of rhaFGF rapidly increased and reached to peak levels at 0.5 hr and then quickly decreased to normal levels at 3 hr after topical application on the wounds. No detectable toxic effects were found by examining multiple organs of the rabbits at 28 days after applying rhaFGF at 900 U/cm2. Topical application of either rhbFGF or rhaFGF at 100 U/cm2 effectively cured the skin wounds in the diabetic patients. Although there was no remarkable difference between groups, rhaFGF provided a slightly better healing rate and efficiency than rhbFGF did. Therefore rhaFGF will become an alternative candidate for diabetic wounds, especially when diabetic wounds were in acidic environment due to bacterial infection.
