In vitro clonal propagation of locally cultivated pink colour Gladiolus var. Neelima through Cormel-sprout culture

Micropropagation provides an economic advantage for the propagation of a particular crop like gladiolus, a beautiful flowering plant which emits expression of love. Propagation by conventional method is a slow process and pathogen keep on accumulation generation after generation which reduces yield and quality of flower and also generates insufficient propagules. An efficient propagation system could overcome those variabilities and meet the increasing demand of propagules production for the growing of gladiolus in the country while it is an exporting plant in Bangladesh. Moreover, establishment of a plant regeneration system through direct organogenesis or via callus is also a prerequisite to further in vitro genetic manipulation of the cultivar. Demand for disease free planting materials is increasing day by day and crop like vegetatively propagated plant is an appropriate means to generate propagules through in vitro techniques. Production of sufficient numbers of plants of a unique genotype is possible using in vitro culture system. In this study, the effect of various concentrations and combinations of plant growth regulators for in vitro regeneration of gladiolus was described using cormel-sprout as explants. However, an efficient in vitro plant regeneration protocol in locally cultivated pink colour Gladiolus var. Neelima was established on MS media with various hormonal supplements using cormel-sprout as explants. Ninety (90) percent of the explants responded for shooting on 0.5 mg/L BA + 0.5 mg/L Kin within the culture initiation period of 90 days. The average number of shoot per explants was 8 ±1.20 and the average shoot length of 12.40 ±2.15 cm were observed in this medium. Shoots are rooted well when they were excised individually and implanted on half strength of MS medium supplemented with 1.0 mg/l IBA, in which 90% of the shoot induced roots. The average number of root per shoot was 10 ± 1.20 and the average root length of 8.50 ± 1.25 cm were observed in this medium after culture of 30 days. Eighty (80) percent of the in vitro raised plantlets were survived in the natural environment.
Governing Equations for Transport in Porous Electrodes

General governing equations for a porous electrode containing three phases (liquid, solid, and gas) are developed using the volume-averaging technique. These equations include the mass transfer in each phase, ohmic drop in the liquid and solid phases, and the equations resulting from applying the principle of conservation of charge. The electrolyte is considered to be a concentrated binary solution.
A New Data Processing Algorithm for the Standard Meter

A new data processing algorithm was proposed against shortcomings in compensating algorithm for data of the standard meter. According to fluid continuity, volume data of flow for the standard meter were normalized so that difference values between calculating volume and standard volume were comparable. Using spline interpolating algorithm flow difference value of arbitrary flow point was obtained. Then this value was changed into corresponding value of present flow point. Approximate data to standard volume was obtained by modifying calculating volume. The algorithm changed three-dimensional interpolating operation into two- dimensional interpolating operation and improved accuracy of interpolating operation and precision of the whole calibrating facility. Results show that the algorithm is of fully operational, easy to implement and effective. Copyright © 2014 IFSA Publishing, S. L.
Type of Chemical Exposition Causes Different Nuclear Abnormality Frequencies

The systematic epidemiological monitoring of populations exposed to chemical agents, is one type of sanitary control that allows early detection of health problems. Human biomonitoring may be conducted with various cytogenetic tests, which evaluate genotoxic effects by detecting DNA damage. One validated and accepted test is the Micronucleus Assay, applied to the buccal epithelial cells. Workers, who were occupationally exposed, participated in our survey: 60 sugar cane cutters, 30 gasoline attendants, and 30 pesticide-sprayer pilots of small airplanes. Comparing the three groups, sugar cane cutters revealed higher fold increase (FI) of abnormalities: pyknotic nuclei (FI=31.4), chromatin condensation (FI=18.8) and binucleated cells (FI=15.0); gasoline attendants exhibited chromatin condensation (FI=14.5) and micronucleus (FI=3.6), and pilots showed severe nuclear abnormalities, counted as binucleated cells (FI=269.5), pyknotic nuclei (FI=54.2) and cells with chromatin condensation (FI=45.2). The biomonitoring of the side effects derived of exposure to genotoxic substances, in the workplace, such as the one we have done for this research, is fundamental for the design of corrective and preventive strategies that assure the health of the worker and biosecure working conditions. Detection of these biomarkers in exposed people indicates genotoxicity events and increased risk of disease development.
1 Examining a positive role psychological for performance measures 1

Emerging evidence suggests that management control systems may generate positive psychological effects, leading to higher levels of managerial performance. We extend this literature by examining the extent to which (1) financial vis-à-vis non-financial measures and (2) diagnostic vis-à-vis interactive utilisation of performance measures may be associated with decreasing role ambiguity and increasing psychological empowerment with performance as the ultimate outcome variable. We find that the interactive utilisation of non-financial performance measures can be particularly important for generating a positive psychological experience and (indirectly) increasing performance. Our study contributes further evidence of the psychologically beneficial role played by management control systems.
Domain relaxation dynamics in epitaxial BiFeO3 films: Role of surface charges

The thermodynamic parameters of domain relaxation process in the absence of external electric fields are related to the intrinsic electrostatic and stress/strain conditions inside the materials, such as the states at surface, states at interface with the electrode, and the atomic defects in the bulk. In order to perform systematical studies of these intrinsic effects, we investigated domain relaxation in a monodomain environment, which was obtained in strained epitaxial BiFeO3 (BFO)(111) films. Without as-grown domain walls and grain boundaries, the epitaxial BFO(111) film provided an ideal system for the dynamic observation of 180-degree domain wall motion. Nano-domains were initially created by writing voltage pulses under the tip of a scanning force microscope and then relaxed through time. The downward polarized domains exhibited much better retention behaviors than the upward domains. A two-step backswitching process was observed, and the behaviors varied with the initial domain sizes. Surface potential measurement showed the dissipation of surface screen charges with time, which was strongly coupled with the 1st step relaxation. The asymmetry behaviors for upward and downward backswitchings, and the two-stage relaxation processes can be explained by the mobile vacancies and the redistribution of surface charges. This study provides the basic understanding of the role of surface charges during the ferroelectric domain relaxation.
Dynamical processes in sequential-bipolar pulse sources supplying nonlinear loads

A uniform basis for analysis of oscillations with essentially non-harmonic shapes, excited by sources of non-smooth or could be discontinuous in time signals is presented. The tool presented here employs non-smooth (impact) systems as a basis to describing not only impact, but also smooth or even linear dynamics. The focus is put on explicit links between impact dynamics and hyperbolic algebras analogously to the link between harmonic oscillations and conventional complex analyses. Illustrations and results of computer simulations are presented. Streszczenie.

Characterization of the interactions of β‒amyloid peptides with glycolipid receptors by surface plasmon resonance

Interactions between β-amyloid (Aβ) peptides and neuronal membranes play an important role in Alzheimer's dis- ease (AD). Using surface plasmon resonance we assayed a kinetic model to study the interactions of Aβ25-35, Aβ40 and Aβ42 with surfaces containing single glycolipids (Asialo-GM1, GM1, GD1a or GT1b). The larger peptides interacted with gangliosides stronger than Aβ25-35, which showed some significant bindings solely at high concentrations under acidic con- ditions. Only the interactions at low Aβ concentrations were useful to calculate the kinetic constants. The affinities increased at low pH. The specificity, but not the affinity correlated with the number of sialic acids in the ganglioside sugar moiety. The most important finding in this study, was a special group of sensorgrams with linear association phases that appeared for the interactions of Aβ with the membranes containing gangliosides, due to the following process: when Aβ is injected at a critical concentration, the first molecules that interact with the gangliosides remain fixed on the membrane. Next A β molecules bind to these fixed molecules, so that for each A β molecule bound, new binding sites are activated on the surface in a linear ratio, which explains the linear shape of the sensorgrams. This way a laminar-arranged Aβ accumulate is progressively formed on the membrane surface and fixed there. These linear sensorgrams were not observe with asialo-GM1 or DMPC, which indicates the main role of sialic acid in these interactions. This model for progressive A β deposition could simulate the initial stage of the Aβ peptide accumulation on cell surfaces.

An alternative approach to absorption measurements of aquatic particles retained on filters

We made modifications to the procedure used for absorption measurements of aquatic particles retained on glass-fiber filters that extend the procedure’s application range to “case 2” waters with high suspended sediment content and allow the determination of phytoplankton pigment absorption in situations where the standard solvent extraction method is not effective. The first result was achieved by combining light-transmission and light-reflection measurements (the latter made possible by the use of a commercially available integrating-sphere attachment for the dual-beam spectrophotometer) so as to remove the spurious contribution to the measured absorption caused by sample backscattering. The second result was obtained by bleaching the sample with a NaClO solution-a method that proved satisfactory even with water-soluble pigments (e.g. the important class of the phycobilins) and solvent-resistant Chlorophyceae. This process also allows for depigmentation of the particle suspension, and thus it was used to evaluate the empirical expression for converting the filter-retained sample absorbance to the equivalent particle suspension value. Both features of the modified procedure have been positively tested through measurements carried out on solvent-resistant phytoplankton species and on samples of inorganic suspended sediment. Light-transmission measurements on particles retained in glass-fiber filters (Yentsch 1962) are convenient for determining the light absorption spectrum of particle suspensions consisting mainly of natural phytoplankton and organic and inorganic detritus (Gordon and Morel 1983). The procedure has two basic advantages: particles can be concentrated so that instrumental accuracy requirements can be met regardless of the high dilution occurring in situ, and information is provided on the absorption of the cells in vivo. The main problem in data analysis arises from the large modification of light transmission due to multiple scattering by the filter, which results in an overestimate of particle absorption relative to suspension state (Butler 1962). Several empirical expressions have been derived for converting the absorption of filter-retained particles (for convenience also referred to as “sample” in the following) to the equivalent absorption of particle suspension. A review on this subject is given by Cleveland and Weidemann ( 199 3). Kishino et al. (1984, 1985) proposed a procedure for discriminating absorption by phytoplankton pigments from absorption by detritus based on measurements performed before and after pigment extraction by methanol. Although some doubts remain about the effectiveness of the procedure (Bricaud and Stramski 1990) and its validity range shows some limitations (little or no effect on some algal species), solvent extraction is the method generally used to identify pigment absorption in natural phytoplankton populations. It is current practice to minimize the loss of forward
Trade Competitiveness of Agroforestry Crop Sector in Sri Lanka

A significant change in the composition of agricultural exports from major plantation crops to non-traditional tree crops such as spices, fruits, and timber which mainly originated from small holder agroforestry systems is evident during the last few decades in Sri Lanka. Development of supply chain for products that are competitive in the world market will enable small holder farmers to reap the economic benefits from agroforestry systems and will make such systems economically viable. The objective of this work was to analyze the trade competitiveness of agroforestry crop sector in the country. Revealed Comparative Export Advantage (RXA), Relative Trade Advantage (RTA) and Revealed Comparative Advantage (RCA) indices were computed for 580 agroforestry products using data extracted from the trade map at the HS level 6. The 580 products were grouped into 82 categories based on the crop origin. The analysis revealed that on average, 58 products had both relative export advantage and revealed comparative advantage and 124 products had relative trade advantage at HS 6 level during 2001-2008. Among the non-traditional exports, fruit crops (avocado, papaya, citrus, pineapple, cashew, lemon and lime, guava, mango, mangosteen and durian), root crops (manioc and arrowroot), medicinal plants (ginger and turmeric), cardamom, coffee, mushroom, bamboo, vanilla, cocoa and beans were found to be competitive in the world market according to relative trade advantage index. Cinnamon fetched the highest RXA, RTA and RCA values, followed by tea, cloves, coconut and nutmeg. The United Arab Emirates, France and Germany were found to be the major export destinations for the products that are highly competitive.

Preparation and properties of microporous structures based on CMC

Carboxymethyl celulose (CMC) is an interesting polymer produced by an easy reaction with chloracetic acid with cellulose. CMC is a hydrophylic polymer soluble in water with huge potential in medical aplications in which we can use an extreme high sorption of water, swelling or senzitivity to pH and temperature – for example as a protection of damaged skin. In this study is presented a method of preparation of porouse nanostructured material based on CMC. This special structure is prepared by following production steps: preparation of film of CMC - basic stabilization of CMC film – formation of gel by sorption of water – frees dryeing of stucture – final stabilization. The stabilization of film is based on changes in CMC based on thermal treatment. The prepared material was evaluated by scanning electron microscopy and infrared spectroscopy. The bahavior in water was tested as well. By the setting of parametres of stabilization of CMC we can obtain structures with different water solubility or different swelling in water. Prepared microporous structures are interesting with large intetnal surface, high wettability and biodegradability. The product of presented technology is nontoxic with high potential in biological aplications.
A longitudinal research aimed at investigating the role of coping styles in the process of change in schema modes

Objective: Literature shows that dysfunctional modes decrease over the course of Schema therapy (ST) (Timmerman, 2014). To our best knowledge no research has been conducted to investigate the role of maladaptive coping styles in the process of change in schema modes. This study makes an attempt to investigate whether modifications in maladaptive coping styles are related to modifications in (dys) functional schema modes in clients with personality disorders (PD) over the course of Schema therapy. Method: The participants are clients who were treated for their PDs at the clinical facility “de Wieke” in Hengelo, the Netherlands. The Young Schema Mode Inventory (SMI), the Young-Rygh Avoidance Inventory (YRAI) and the Young Compensation Inventory (YCI) were administered to measure the prevalence of (dys) functional schema modes and dysfunctional coping styles. Participants were asked to fill in the SMI, YCI and YRAI at four points in time: pre-, mid-, post-treatment and at the follow up-period six months after the treatment. Univariate analyses of variance, correlational analyses and a logistic regression analysis were carried out in order to explore the data of participants who filled in all four measurements. Results: The dysfunctional coping styles as well as dysfunctional schema modes showed significant differences at the second half of the treatment, from pre-treatment to post-treatment and pre-treatment to follow-up. Findings also showed that avoidance strategies have a predictive value on the positive modification of functional modes. Discussion/Conclusion: ST in a clinical group setting shows promising results regarding the decrease of dysfunctional coping styles and dysfunctional schema modes as well as the increase of functional modes. The decrease of dysfunctional coping styles, especially avoidance styles, seems to be related to decreases in dysfunctional schema modes as well as increases in functional schema modes. This indicates that interventions aimed at containing or preventing avoidance strategies requires more attention in ST.
Design and Implementation of the Remote Wireless Intraoral Endoscope System

Oral health is one of the most important parts of the body health. It is very significant to periodically inspect the status of our oral cavity so as to maintain and improve the quality of our lives. Recently, oral inspection is usually carried out only in the hospital. People are unable to inspect their oral cavity by their own due to lack of professional tools and specialized knowledge. Therefore, a Remote Wireless Intraoral Endoscope System is proposed in this paper, which is consisted of two parts: a probe for wirelessly collecting the image of oral cavity by using a CMOS imaging sensor and an interactive display unit for both displaying the image collected by the probe and interacting with remote server. Our design and implementation shows the validity and practicability of the system.
Theoretical multiplicity for the governance of transitions. The energy producing greenhouse case

Transition management has become an important topic in scientific research on sustainable development over the last decade. A recurring question is whether, and if so how, transitions towards sustainability can be governed. In this paper we address this question by theoretically comparing transition management theory with a number of related theories on governing societal change, such as multi-actor collaboration, network governance, policy agenda setting and adaptive management. We illustrate the different approaches by analysing the Dutch transition case of the greenhouse as a source of energy from different theoretical perspectives. We conclude that these theories reveal additional and more varied leadership mechanisms and steering options than the overarching approach of transition management alone. Therefore, we suggest an approach of theoretical multiplicity, arguing that multiple theories need to be applied simultaneously for dealing with the complex societal sustainability issues.
Dynamic node join algorithm with rate-distortion for P2P live multipath networks

The delivery of multimedia that efficiently maximizes its quality in changing network conditions is one of the most challenging tasks in the design of live streaming systems. This study attempts to improve current P2P (peer-to-peer) live streaming systems by allowing users to enjoy high-quality service under the limitations of network resources. The proposed improvement method involves summing up and analyzing the consideration factors and restriction factors involving live stream quality during system operations. The proposed R-D (Rate-Distortion) optimized dynamic nodes join algorithm is based on multipath streaming concept and receiver-driven approach. This distributed algorithm enables the system to evaluate the current network status, in order to optimize the end-to-end distortion of P2P networks. Results of this study demonstrate the effectiveness of the proposed approach.
An epigenomic roadmap to induced pluripotency - DNA methylation as a reprogramming modulator-

An epigenomic roadmap to induced pluripotency DNA methylation as a reprogramming modulatorDong-Sung Lee Major in Biomedical Science Department of Biomedical Science Seoul National University Graduate School Introduction: During cellular reprogramming to induced pluripotent stem cells (iPSCs), somatic cells rebuild their epigenetic architecture to acquire a steady self-renewing state. The biological significance and mechanisms of this epigenetic remodeling have remained unclear. Methods: Here we characterize the epigenomic roadmap to pluripotency at base resolution by performing whole genome bisulfite sequencing of samples from secondary reprogramming system. We investigated the changes in differentially methylated regions (DMRs) and integrated this with analysis of histone modifications.
