Impact of introducing alien storage proteins on the bread-making quality and agronomic performance of spring wheat

The relatively narrow genetic base of spring wheat grown in western Canada puts the crop at risk from attack by pests which reduce yield and marketability. Interspecific hybridization is used to introduce new genetic sources of resistance to wheat pests. This study was conducted in order to evaluate the effectiveness of endosperm protein fingerprinting in selecting backcross-derived (BC) lines from the cross Park*3/ T. timopheevi. SDS-PAGE and A-PAGE were used to identify the high molecular weight (HMW) glutenin subunit and gliadin constitution, respectively, of the BC lines. Although no exotic HMW glutenin subunits were present in the BC lines, a high frequency lacked the 'A' genome subunit. This 'null' condition was deleterious to bread-making quality. The BC lines with the null condition were characterized by the transfer of novel omega and ga.mlna gliadin proteins from T. timopheevi and kernel texture normally associated with tetraploid wheat. Despite the level of back-crossing, a large majority of the lines were inferior to the recurrent parent for agronomic performance. Delayed heading, resulting from the putative transfer of a major maturity gene from T. timopheevi, was associated with low grain yield in 1991 but higher yield in 1992. Lines with improved baking quality tended to be low-yielding. Based on this study, protein fingerprinting can be used to select interspecific lines with desirable end-use quality.
Multi-authority Attribute Based Encryption with Attribute Revocation

Multi authority attribute based encryption solve a completely trust problem about a single authorization center, make the data owner control fine-grained data and resist collusion attack. But in the practical attribute revocation needs a lot of calculation. Adding the user revocation list into cipher text implements the user revocation. Through agent re-encryption technology, decryption outsourcing technology and time division revocation re-vocation, we implement attributes revocation satisfying the forward security and backward security on the basis of the effective fine grained, meanwhile reducing the computational overhead when the attribute is revoked.
Error Sources Influencing Performance Assessment Reliability or Generalizability: A Meta Analysis.

As performance-based assessments have gained wider use, there are increasing concerns about their dependability. This study is a synthesis of existing studies regarding the reliability or generalizability of performance assessments. The meta-analysis involves summarizing, examining, and evaluating research findings. Articles on the dependability of performance assessments, analyzed through traditional means or a generalizability framework published after 1980 were selected. The literature search yielded 22 studies meeting the criteria for inclusion. These 22 studies yielded 258 different reliability or generalizability coefficients. Task and occasion facets contributed the greatest proportion of variance to estimates of error in the measurement procedure. Both are inherent in the construction of many performance tasks. The judge facet did not contribute a large proportion of error variance. Critics of performance assessment should not worry that the use of professional judgment to score performance assessment will be a major source of measurement error.

Logic-based switching for the stabilization of stochastic systems in presence of unmodeled dynamics

We describe a supervisory control scheme for adaptively stabilizing an unknown discrete time linear system affected by a possibly unbounded noise. The scheme incorporates a switching logic mechanism, which, at adaptively selected event times, places in feedback with the system the controller designed for the model which is the best according to the least squares criterion. The event times are chosen so as to uniformly stabilize the estimated system. We show that, when the controller selection is based on a reduced order model of the system and the unmodeled dynamics is sufficiently small, the introduced switching scheme is successful in stabilizing the system. Moreover, in absence of unmodeled dynamics, we are also able to characterize the switching scheme performance in terms of a self-tuning result.
Is trade facilitation the right direction to go in building trade capacity

This paper uses the gravity equation of international trade to study the relationship between trade facilitation commitments and trade flows using the OECDIWTO Trade Capacity Building Trade Facilitation Database. In the analyses of 257 donor-recipients pairs, it is found that bilateral trade facilitation commitments are positively related, while multilateral sources are negatively related to exports from recipients to donors. These negative relationships for the multilateral institutions were found by using cross-sectional studies and are significant, for all but the World Customs Organization. From the firstdifferenced estimations, changes in exports from recipients to donors covariate positively with changes in the World Customs Organization trade facilitation commitments; the estimated effect is 0.23 percent to 0.41 percent increase in exports for every 10 percent increase in the World Customs Organization trade facilitation commitments. There is no evidence that changes in other trade facilitation sources will bring significant changes to bilateral trade.
The Experience of Class Tutors in a Peer Tutoring Programme: A Novel Theoretical Framework.

The following paper presents the first known examination of the experiences of class tutors within a peer-assisted learning program. Three female first-year class tutors, aged 25-28 years, provided insight into how they experienced a novel peer tutoring programme embedded in their tutorials. Using grounded theory techniques, it was found that the following five themes underlie their experiences: role exploration, sharing responsibility, regulation of the peer tutored groups, harnessing the peer tutors' role, and community. Literature from the domain was examined post-hoc and was found to complement these themes. Additionally, it was found that class tutors were beneficiaries of the programme. It was suggested that future research address the limitations of the present study and test a number of hypotheses within a novel theoretical framework. The hypotheses were constructed to include the key roles within embedded peer tutoring, and learning climate typologies and dimensions (Little, 1975).
MILITARY EXPENDITURE AND ECONOMIC GROWTH IN MIDDLE EASTERN COUNTRIES: A DYNAMIC PANEL DATA ANALYSIS

Defence expenditures have both costs and benefits to the economy. The costs of defence expenditures are mainly emphasized as opportunity costs. On the other hand, defence spending may have growth‐promoting potential benefits: a rise in defence spending may result in a higher aggregate demand, production and employment. This paper examines empirically the effects of military expenditures on economic growth for Middle Eastern countries and Turkey, for the time‐period 1989–1999. The relationship between military expenditure and economic growth is investigated by using cross‐section and dynamic panel estimation techniques. Empirical analysis indicates that military expenditure enhances economic growth in the Middle Eastern countries and Turkey as a whole.
Soft contribution to the damping rate of a hard photon in a weakly magnetized hot medium

We consider weakly magnetized hot QED plasma comprising electrons and positrons. There are three distinct dispersive (longitudinal and two transverse) modes of a photon in a thermo-magnetic medium. At lowest order in coupling constant, photon is damped in this medium via Compton scattering and pair creation process. We evaluate the damping rate of hard photon by calculating the imaginary part of the each transverse dispersive modes in a thermo-magnetic QED medium. We note that one of the fermions in the loop of one-loop photon self-energy is considered as soft and the other one is hard. Considering the resummed fermion propagator in a weakly magnetized medium for the soft fermion and the Schwinger propagator for hard fermion, we calculate the soft contribution to the damping rate of hard photon. In weak field approximation the thermal and thermo-magnetic contributions to damping rate get separated out for each transverse dispersive mode. The total damping rate for each dispersive mode in presence of magnetic field is found to be reduced than that of the thermal one. This formalism can easily be extended to QCD plasma.
The influence of BHA, BHT and TBHQ on the oxidation stability of soybean oil ethyl esters (biodiesel)

The effect of synthetic antioxidants such as BHT (butyl-hydroxytoluene), BHA (butyl-hydroxyanisol) and TBHQ (t-butyl-hydroxyquinone) was evaluated on the induction time of soybean oil ethyl esters with low oxidation stability, employing the Rancimat method (EN14112). Interaction effects were also investigated by employing a 23 factorial design, which had as minimum and maximum levels the concentrations of zero and 1500 ppm of each antioxidant. Among the synthetic antioxidants evaluated, BHT displayed the highest effectiveness in the concentration range from 200 to 7000 ppm. TBHQ displayed a greater stabilizing potential when used at higher concentrations (8000 ppm), while BHA was found to provide no noticeable increase in the induction time at concentrations greater than 2000 ppm. The combined use of these antioxidants, at the levels tested in this study, yielded no evidence of any positive synergic effect that would justify their use in binary or ternary mixtures.
Foraging activity and immunocompetence in workers of the bumble bee, Bombus terrestris L

A fundamental assumption of coevolutionary models of host-parasite relations is that resistance is costly. Costs are envisioned as phenotypic or genetic trade-offs in the allocation of limited resources to specific tasks. Using workers of the bumble bee Bombus terrestris L. , we tested experimentally whether foraging effort, an energetically costly and crucially important task that ensures colony growth, survival and reproduction, is costly in terms of reduced resistance against parasite attack. The experiment showed that indeed workers allowed to forage showed lower levels of immunocompetence, as measured by the degree of encapsulation of a novel antigen, than workers prevented from foraging activity.
An Empirical Study of the Relationship Between Young Adults Consumers Characterized by Religiously-Oriented Family Communication Environment and Materialism

The purpose of this study is to examine the relationship between young adult consumers who are characterized by a particular family communication pattern at home, and their level of materialistic values. The data was collected through self-administered questionnaires. A general profile of the respondents is discussed in the study, and the sample consisted of 956 respondents. The majority of the respondents were Malays followed by Chinese and Indians. The proportion of female respondents was higher than the male respondents. Most of the respondents were single and in the age group of between 19-29 years old. Pearson correlation was employed to examine the associations between the main constructs of the proposed model. Specifically, it was found that the correlation coefficient between materialism and socio-oriented family communication, concept-oriented family communication and religiously-oriented family communication were positive and significant. Internal consistency reliability assessment using Cronbach coefficient alpha revealed that all the four dimensions had high reliability.

Effective Truncation of a Student's t-Distribution by Truncation of the Chi Distribution in a Chi-Normal Mixture

A Student’s t-distribution is obtained from a weighted average over the standard deviation of a normal distribution, σ, when 1/σ is distributed as chi. Left truncation at q of the chi distribution in the mixing integral leads to an effectively truncated Student’s t-distribution with tails that decay as exp (-q2t2). The effect of truncation of the chi distribution in a chi-normal mixture is investigated and expressions for the pdf, the variance, and the kurtosis of the t-like distribution that arises from the mixture of a left-truncated chi and a normal distribution are given for selected degrees of freedom 5. This work has value in pricing financial assets, in understanding the Student’s t--distribution, in statistical inference, and in analysis of data.
Characteristics of Immobilized Urease on Grafted Alginate Bead Systems

This study evaluated the biological importance of immobilized urease enzyme over the free urease. The support material used for urease immobilization was alginate. Generally, the immobilization of urease in alginate gel showed a marked increase in Km and Vmax. However, the immobilized urease showed higher thermal stability than that of free enzyme. The rate of thermal inactivation of the immobilized enzyme decreased due to entrapment in gel matrix. Also, the activity of the immobilized urease was more stable in retention than that of the free enzyme during the storage in solution, although the activity of the immobilized enzyme was lower in comparison with the free enzyme. A stable immobilized system and long storage life are convenient for applications that would not be feasible with a soluble enzyme system. These results highlighted the technical and biochemical benefits of immobilized urease over the free enzyme.
Mindful Pregnancy and Childbirth: Effects of a Mindfulness- Based Intervention on Women's Psychological Distress and Well-being in the Perinatal Period

This pilot study explored the effects of an 8-week mindfulness-based cognitive therapy group on pregnant women. Participants reported a decline in measures of depression, stress and anxiety; with these improvements continuing into the postnatal period. Increases in mind-fulness and self-compassion scores were also observed over time. Themes identified from interviews describing the experience of participants were: 'stop and think', 'prior experience or expectations', 'embracing the present', 'acceptance' and 'shared experience'. Childbirth preparation classes might benefit from incorporating training in mindfulness.
Novel Robust Exponential Stability of Markovian Jumping Impulsive Delayed Neural Networks of Neutral-Type with Stochastic Perturbation

The robust exponential stability problem for a class of uncertain impulsive stochastic neural networks of neutral-type with Markovian parameters and mixed time-varying delays is investigated. By constructing a proper exponential-type Lyapunov-Krasovskii functional and employing Jensen integral inequality, free-weight matrix method, some novel delay-dependent stability criteria that ensure the robust exponential stability in mean square of the trivial solution of the considered networks are established in the form of linear matrix inequalities (LMIs). The proposed results do not require the derivatives of discrete and distributed time-varying delays to be 0 or smaller than 1. Moreover, the main contribution of the proposed approach compared with related methods lies in the use of three types of impulses. Finally, two numerical examples are worked out to verify the effectiveness and less conservativeness of our theoretical results over existing literature.

Methodology for the characterization and identification by sem-eds of atmospheric particles from different pollutions emission

The methodology employed in this study enable the characterization of diverse particles in the Western Mexico (state of Colima). The identification of the morphology and chemical composition of these particles provides valuable information for the determination of their origin. The results presented in this chapter show the presence of a wide diversity of particles from natural and anthropogenic origin. A total of 3600 particles were analyzed by SEM;EDS and then classified by their chemical composition and morphology in order of abundance: those rich in Fe, Si;Al, Cl;Na, Ca, Ba; and to a lesser abundance, particles rich in heavy metals such as Pb and V;Ni were observed. The statistics analysis of the results from SEM–EDS microanalysis determined the main elements of the different particle groups and related them to their origin, such as crustal/farming; fuel;oil; marine; volcanic activity and industry. The present information in this study could be utilized in other places to identify atmospheric particles from different pollutants emissions.
Cation diffusion in LaMnO 3 , LaCoO 3 and LaFeO 3 materials

Reaction kinetics between dense, polycrystalline pellets of La2O3 and Mn3O4 were investigated at temperatures 1370-1673 K and oxygen partial pressures 40 Pa 50 kPa. The formation of single product phase, nonstoichiometric La1-xMn1-yO3±δ, was confirmed by Xray diffraction and electron microprobe analysis. The solid solubility limits of La1-xMn1yO3±δ determined by wave dispersive spectroscopy were in good agreement with previous reports and equilibrium was achieved at the phase boundaries in the diffusion couples. Vacancies at the La and O sub-lattices are proposed to be the dominating point defects in the product layer. The growth of the product phase followed the parabolic rate law regardless of temperature and oxygen partial pressure. Location of Pt-markers demonstrated that diffusion of Mn cations in La1-xMn1-yO3±δ dominated over diffusion of La. The diffusion coefficient of Mn was determined from the parabolic rate constant and activation energy of (280±40) kJ mol was found. Results are discussed in relation to cation diffusion in other LaBO3±δ oxides (B = Cr, Mn, Fe).
Random graphs and Lindstrom quantifiers for natural graph properties

We study zero-one laws for random graphs. We focus on the following question that was asked by many: Given a graph property P, is there a language of graphs able to express P while obeying the zeroone law? Our results show that on the one hand there is a (regular) language able to express connectivity and k-colorability for any constant k and still obey the zero-one law. On the other hand we show that in any (semiregular) language strong enough to express Hamiltonicity one can interpret arithmetic and thus the zero-one law fails miserably. This answers a question of Blass and Harary.
SOCIAL NETWORK SERVICES: AN OVERVIEW

The past few years a tremendous growth on Online Social Networks such a Facebook, Orkut and Twitter is seen. These OSNs not only offer attractive means for virtual social interactions and data sharing, but also raise a number of security issues. Although OSNs allow a single user to access to her or his data, they currently do not provide any mechanism to enforce privacy protection over data associated with large number of users, leaving privacy violations largely unresolved and leading to the potential disclosure of information that at least one user intended to keep private. This paper analyses the various privacy and security issues in OSNs. OSNs come across various types of attacks such a fake identity, Sybil attacks, Identity clone attacks, The main aim is to enhance the privacy and security in OSNs which is one of the Quality of Service (QoS) issues and thereby decreasing the attacks and issues. This paper is a survey which is more specific to expose the various attacks and privacy models in OSNs with respect to enhancement of security and privacy.
