Antioxidant Activities of Triticum aestivum L. Leaves Collected at Different Stages of Growth

A b s t r a c t K e y w o r d s Medicinal plants continue to provide valuable therapeutic agents, both in modern medicine and in traditional system. They are natural sources yielding valuable food or herbal products, which are often used in the treatment of various diseases. One such plant is Triticum aestivum L. (wheat grass), the plant known for its nutritive value, has been called one of nature s finest medicines. Wheat grass is fast becoming one of the most widely used supplemented health foods. The objective of the study was to assess the levels of non-enzymatic antioxidants and the activities of enzymic antioxidants in T. aestivum leaves collected at three different stages of growth [4, 8 and 12 days after sowing (DAS)]. The results showed that the leaves collected at 4 DAS had higher contents of both enzymic and nonenzymic antioxidants and also exhibited good antioxidant activity. The results of the present study show that the leaves of T. aestivum at their early stages of growth are excellent sources of antioxidants, as a primary antioxidant that reacts with free radicals.

THE ROLE OF THE DELAY TIME IN THE MODELING OF BIOLOGICAL RANGE EXPANSIONS

The time interval between successive migrations of biological species causes a delay time in the reaction-diffusion equations describing their space-time dynamics. This lowers the predicted speed of the waves of advance, as compared to classical models. It has been shown that this delay-time effect improves the modeling of human range expan- sions. Here, we demonstrate that it can also be important for other species. We present two new examples where the predictions of the time-delayed and the classical (Fisher) ap- proaches are compared to experimental data. No free or adjustable parameters are used. We show that the importance of the delay effect depends on the dimensionless product of the initial growth rate and the delay time. We argue that the delay effect should be taken into account in the modeling of range expansions for biological species.
Attention differences in viewing physics diagrams among experts and novices

It is known that experts identify/perceive meaningful patterns in visual stimuli related to their domain of expertise. This study explores the speed with which experts and novices detect changes in physics diagrams. Since change detection depends on where individuals direct their attention, differences in the speed with which experts and novices detect changes to diagrams would suggest differences in attention allocation between experts and novices. We present data from an experiment using the "flicker technique,” in which both physics experts and physics novices viewed nearly identical pairs of diagrams that are representative of typical introductory physics situations. The two diagrams in each pair contain a subtle difference that either does, or does not change the underlying physics depicted in the diagram. Findings indicate that experts are faster at detecting physics-relevant changes than physics-irrelevant changes, however there is no difference in response time for novices, suggesting that expertise guides attention for experts when inspecting physics diagrams. We discuss the cognitive implications of our findings. PACS: 01.40. Fk, 01.40. Ha, 01.40. -d
The Context Of Knowledge In Organizations From Resource Based Theory To Knowledge Based Theory: A Conceptual Review

Nowadays, organizations in order to increase their competitive advantages, they put more focus on managing the intangible assets rather than the tangible assets including the intellectual capital. Since the value of intellectual capital is resided in the talented human capital, therefore the talent management is commonly used for human resource management. The root of talent management is came from the Resource Based Theory (RBT) that treats the human capital as static assets that only need to be attracted, developed, updated, deployed and retained. In contrast, this paper appreciates the talent as an individual tacit knowledge that more than the said above, it can be created, captured and transferred, which is aligned with the Knowledge Based Theory (KBT).
Quality of Service Enhancement of Wireless Sensor Network Using Symmetric Key Cryptographic Schemes

A Wireless Sensor Network is a combination of spatially distributed independent nodes deployed in dense environment, communicating wirelessly over limited bandwidth and frequency. Security and Qos is the major concern in wireless sensor network due to its wireless communication nature and constraints like low computation capability, less memory, bounded energy resources, susceptibility to physical capture or damages and the use of insecure wireless communication channels. These constraints make security along with the QoS, a challenge in wireless sensor network. The cryptographic schemes increases the level of security and make it secure against critical attacks but also has a significant impact on the QoS of wireless sensor network. In this paper, the different cryptographic schemes based on asymmetric key and symmetric key cryptography are evaluated. The symmetric key cryptography schemes require less time for processing, less power and also require less storage space as compared to asymmetric key cryptographic schemes, results in less impact on the QoS of wireless sensor network. In this paper, the QoS of wireless sensor network along with cryptographic schemes will be evaluated on the basis of metrics like throughput, jitter, end- to-end delay, total packet received and energy consumption.
The Analysis of Influence of Job Stressor upon Performance and Turnover Intention of Broker–Dealer of Equity Securities Companies in Surabaya

The long-term goal of this research is to make the Indonesian capital market equals/parallel to other capital markets in the Asia Pacific region. The research is conducted in securities companies which are Members of Indonesia Stock Exchange located in Surabaya City, East Java Province. The number of domestic investors in the capital market in Indonesia is still very limited, reaching only about 400 thousand people, or less than 0.1% of the number of Indonesias middle class who already have securities accounts as an active sign of becoming a financier in the stock exchange (Afifuddin, 2011). This situation is a problem that needs to get serious attention from the government to enliven the Indonesian capital market, so the dream of making the Indonesian capital market parallel to the capital markets in the Asia Pacific region can be realized. The number of domestic investors needs to be increased so that ownership of equity securities (shares) is not only dominated by foreign investors.
Freeze-lysable inorganic nutrients in intertidal sediments: dependence on microphytobenthos abundance

Freezing is a common treatment for the preservation of sediment samples. To test the role of microphytobenthos (MPB) abundance in the release of intracellular nutrients to the pore water due to cell breakage after freezing, referred to as freeze-lysable inorganic nutrients (FL-IN), parallel extractions were carried out from intertidal sediment cores collected in winter and summer from Cadiz Bay. After the determination of net production and dark respiration rates with O2 microsensors, sediment cores were subcored and sliced into several layers. The samples were divided into 2 frac- tions; the first was centrifuged to extract pore water (fresh) and the other was frozen at -80°C, thawed and centrifuged to extract pore water after freezing. NO2 - , NO3 - , NH4 + and PO4 3- were measured in the pore water extracted by both procedures. Chlorophylls a and c were extracted from the same sed- iment fractions. Freezing produced a significant increase in the pore water concentrations of all inor- ganic nutrients. Therefore, if the variable of interest is the inorganic nutrient concentration, pore water should be extracted from fresh samples. In addition, FL-IN correlated significantly with chloro- phylls a and c (p < 0.01), r 2 ranged from 0.54 for NO3 - to 0.94 for NH4 + , indicating that most FL-IN were released from MPB biomass. The relationships between chlorophyll a and FL-IN in winter and summer were significantly different, suggesting that nutrient accumulation by MPB changes season- ally and might affect nutrient cycling in intertidal sediments.
Effect of Volleyball Training Background and Warm-Up Exercise on Passive Kinematics and Musculo-Articular Impedance of the Knee Joint

Knee injuries are common in sport competitions. Risks of injuries can be significantly lowered by warm-up exercise prior to intense activity. This study aimed to determine simultaneously the long-term effect of competitive volleyball training and short-term effect of a warm-up exercise on passive kinematics and musculo-articular impedance of the knee joint. Twelve professional volleyball players (mean age 23.8 ± 3.9 years, weight 71.5 ± 7.1kg and height 1.75 ± 0.07m) and 12 moderately active subjects (mean age 20.2 ± 1.1 years, weight 63.2 ± 9.6 kg and height 1.63 ± 0.05 m) participated in the study. Passive knee joint kinematics (number of oscillations, start and end angles, total duration of oscillations, first four peak flexion angles, first peak extension angle, period of the first three cycles, plateau amplitude, amplitude of first flexion and extension, Flexion and Extension Relaxation Indexes), stiffness and viscosity were investigated using a leg drop pendulum test performed before and after a warm-up exercise consisting of a 10-minute treadmill running. Results showed no effect of competitive volleyball training background on knee joint kinematics, stiffness and viscosity. However, in the moderately active subjects, amplitude of the first flexion and Flexion Relaxation Index were significantly higher after the running exercise than before, reflecting greater musculo-articular compliance of the knee after the warm-up compared to volleyball players. In conclusion, no change in the stiffness of the knee in volleyball players could be beneficial to the practice of volleyball since insufficient lower limb stiffness may destabilize joint motion and increase the incidence of soft tissue injuries.

Investigating the simultaneous process design and control of a membrane reactor for hydrogen production via methane steam reforming

In the present work, the simultaneous process design and control of a membrane reactor for H2 production via methane steam reforming (MSR) is performed. The problem is stated as a non-linear optimization problem with non-linear constraints, which includes economic and controllability criteria in the objective function. A linear model predictive controller (MPC) is implemented to enforce the desired dynamic performance. Utilizing this methodology two pre-defined process flowsheets for H2 production through the low temperature MSR, utilizing palladium-based membranes, are optimally designed based on economic criteria in the form of annualized capital and operating cost, and controllability criteria, in the form of the sum of squared errors during dynamic transitions. The first flowsheet is consisted of an integrated membrane reactor (IMR), whereas the second flowsheet under consideration is consisted of a cascaded arrangement between a reactor and a membrane module in series (CRM). Several other auxiliary processes such as heat exchangers, splitters, and mixers are employed. Rigorous nonlinear dynamic models have been developed assuming one dimensional transport and pseudo-homogenous conditions in the reaction zone in order to emulate the plant dynamics, whereas a linearized version of it is used by the MPC algorithm. Optimization results demonstrate the ability of the integrated process and control design framework to achieve a superior operating performance for a range of several factors affecting the operating conditions of the reactor.
ANALYSIS OF THE RISK OF COMPANY’S BANKRUPTCY IN POLISH FOOD AND BEVERAGE PRODUCTION SECTOR USING THE COX REGRESSION

Analysis of the risk of a company’s bankruptcy in Polish food and beverages production sector (NACE, No. 15) has been carried out using econometric modelling in the form of the Cox regression. The purpose of this paper was to find factors (models) describing the risk of a company’s bankruptcy. The described approach to modelling of the risk of bankruptcy is – in the case of quantitative variables – the use of “raw” positions from financial accounts.
Hybrid Techniques of Combinatorial Optimization with Application to Retail Credit Risk Assessment

Hybrid techniques of combinatorial optimization are a growing research area, designed to solve complex optimization problems. In the first part of this paper, we focus on the methodological background of hybrid techniques of combinatorial optimization, paying special attention to the important concepts in the field of combinatorial optimization and computational complexity theory, as well as to hybridization strategies that are important in the development of hybrid techniques of combinatorial optimization. According to the presented relations among the techniques of combinatorial optimization, the strategies of combining them and the concepts for solving combinatorial optimization problems, this paper presents an example of the hybrid technique for feature selection and classification in credit risk assessment. This study emphasizes the importance of hybridization as a concept of cooperation among metaheuristics and other optimization techniques. The importance of such cooperation is confirmed by the results that are presented in the experimental part of the paper, which were obtained on a German credit dataset using the hybrid technique of combinatorial optimization based on a low-level relay strategy. The experimental results show that the proposed method outperforms, on the same dataset, the methods presented in the literature in terms of the average prediction accuracy.
Evaluation of Ecosystem services of Villorita cyprinoides in Vembanad

Vembanad Lake, a wetland of international importance, famous for waterfowl habitat was designated a Ramsar site, for conservation and sustainable utilisation of the ecosystem. Millennium ecosystem assessment (2005) emphasises that the various services provided by the ecosystem benefitting human population needs to be identified and evaluated for judicious utilisation of the resources. Villorita cyprinoides is a major species contributing to the molluscan fishery of Vembanad lake. The study involving Villorita sp. was taken up with the objectives of development of a conceptual framework encompassing the different ecosystem services provided by the clam resources, estimation of the values of selected ecosystem services using appropriate proxies and analysis of the trade-offs between anthropogenic activities like dredging vis-a-vis clam resources utilizations following the principles of MEA (2005). The study identified that the clam fisheries in the lake is most acknowledged for its provisioning ecosystem services. Apart from the regulating services such as water quality maintenance and carbon sequestration, the cultural and the linking services provided by clam fisheries to human are also identified. In spite of the identification of the various services, the non-realisation of the value of the services provided by clam fisheries has prompted the destruction of the resource knowingly or unknowingly by our activities. One of the anthropogenic activities affecting the clam fisheries is the dredging of sub fossil deposits of clamshell or white clams which are good sources of calcium carbonate for cement manufacturers. Identifying the lacunae of non-realisation of the services of clam resources, the paper has judiciously attempted not only to evaluate the services of the ecosystem service provider but also to externalize the internalities in the ecosystem services evaluation process by considering the various social costs and benefits associated with the resource.
Working Paper Series Financial Development and Inequality: Brazil 1985-99

We examine the impact that financial development had on earnings inequality in Brazil in the 1980’s and 90’s. The empirical evidence, based on panel time series and time series data, shows that more broad access to financial and credit markets had a significant and robust effect in reducing inequality during the period investigated. We suggest that this is not only because the poor can invest the acquired credit in all sorts of productive activities, but also because those with access to financial markets can insulate themselves against recurrent poor macroeconomic performance, which is exemplified by high inflation rates. The main implication of the results is that a seemingly non-distortionary policy, such as more credit aimed at the poor, alleviates the extreme inequality present in Brazil and consequently improves welfare without distorting economic efficiency.
A Multi-Agent Framework for Web Based Information Retrieval and Filtering

Searching for information on the Web is a time consuming task. To help users and to speed up searching for relevant documents efficient retrieval and filtering techniques are needed. To increase the efficiency of information retrieval and filtering tasks, intelligent agents have been widely studied and deployed. In this paper, we present a general agent framework for retrieving and filtering relevant/irrelevant documents.
Victim and Observer Asymmetries in Their Reactions to an Apology: How Responsibility Attribution and Emotional Empathy Lead to Forgiveness

本研究は，侵害者が行う謝罪に対して，実際の被害者と，被害の観察者とが異なる反応を示すという傾向を検討した。 特に，謝罪によってもたらされる「許し」の動機づけと，さらにその規定因となる責任帰属や情緒的共感といった変数に注目し，被害者と観察者の謝罪に対する反応の差異を検討した。 大学生136名に対して，被害者／観察者の視点を操作した被害場面シナリオ，及び侵害者による自発性を操作した謝罪シナリオを段階的に提示し，各段階で侵害者への反応を測定した。 その結果，「許し」の動機づけに関しては，視点と謝罪タイプの交互作用が見られ，非自発的な謝罪は，観察者のみに対して「許し」の促進効果を持っていた。 さらに，謝罪が「許し」を規定する媒介過程においても，視点間の非対称性が示された。 観察者においては，謝罪は責任判断と情緒的共感の両者の変数と介して「許し」を規定していたのに対して，被害者においては，情緒共感のみがそのような役割を担っていた。 以上の結果から，対人葛藤場面においては，その被害者と観察者の判断を動機づける要因が異なることが示唆される。
Spatial Besov Regularity for Stochastic Partial Differential Equations on Lipschitz Domains

We use the scale of Besov spaces B^\alpha_{\tau,\tau}(O), \alpha>0, 1/\tau=\alpha/d+1/p, p fixed, to study the spatial regularity of the solutions of linear parabolic stochastic partial differential equations on bounded Lipschitz domains O\subset R^d. The Besov smoothness determines the order of convergence that can be achieved by nonlinear approximation schemes. The proofs are based on a combination of weighted Sobolev estimates and characterizations of Besov spaces by wavelet expansions.

Educational design as transdisciplinary partnership: supporting assessment design for online

The design of student assessment for the online context can be a disquieting experience without the support of colleagues and a group of peers from across a range of disciplines with whom to share ideas. This paper reports on interviews conducted with academic “peak performers” as well as some educational design practitioners about the current practices of designing for online assessment. A transdisciplinary approach to educational design is proposed for further exploration.

Resonantly damped oscillations of a system of two coronal loops

Context. Rapidly damped transverse oscillations of coronal loop systems are often observed. Aims. We aim to study analytically the resonantly damped oscillations of a system of two not necessarily identical coronal loops and their dependence on the equilibrium parameters, improving on and extending the results for two identical coronal loops. Methods. The linearised magnetohydrodynamic equations for a cold plasma were solved in the long-wavelength limit and for thin boundary layers in bicylindrical coordinates. We investigated the effects of the density contrast between the two loops, the thickness of their inhomogeneous layers, and the separation distance between them. The complex spectrum was also studied. Results. We obtained more general expressions for the linear damping rate of the transverse oscillations in a system of two coronal loops. The results can be reduced to expressions found previously for the special cases of one vanishing loop or two identical loops. The interaction between the loops results in a stronger damping of the high-frequency eigenoscillation in comparison with that of the low-frequency eigenoscillation. By decreasing the distance between loops, the efficiency of resonant damping is reduced.
