THE METHOD OF FUNDEMENTAL SOLUTIONS FOR THE MULTI-DIMENSIONAL WAVE EQUATIONS

In this paper, a meshless method is developed for solving multi-dimensional wave equations. The proposed method is based on the method of particular solution (MPS), the method of fundamental solutions (MFS) and the Houbolt finite difference (FD) method. The wave equation is considered as a Poisson-type equation with the time-dependent source term. The Houbolt method is applied to avoid the difficult problems for dealing with the initial conditions in forming the linear algebra system. The works of space discretization are dependent on the method of particular solution and the method of fundamental solutions. There are three numerical examples considered in this paper, such as the string vibration and wave vibration problems. Numerical validations have proven that the proposed method is a highly efficient and accurate meshless numerical tool for solving wave equations in engineering and sciences by comparing with analytical solution and other numerical solutions.
Behavior of Flavor Release from Emulsified d -Limonene in Spray-dried Powders with Various Wall Materials

Release rates of d -limonene from spray-dried powders were investigated for various wall materials such as maltodextrin (MD) (dextrose equivalent (DE) ＝ 25 and 19), α -lactose, and sucrose. Spray-dried powder of d -limonene emulsified with hydrolyzed whey protein was prepared with the solid content of 60 wt% and containing 53.9 wt% d -limonene and medium chain triglyceride (MCT) oil (weight ratio ( d -limonene/MCT oil) of 0.20), 35.7 wt% carrier solution with wall material, and 7 wt% hydrolyzed whey protein. The release rate of d -limonene from the spray-dried powders was measured under storage conditions with constant temperature of 50 ℃ and maintained at different relative humidity (RH). The release rate of d -limonene increased at higher RH and was significantly dependent on the wall material. Logarithm of release rate constant was proportional to RH for spray-dried powders of lactose and MD (DE ＝ 25 and 19) above 68% RH.
Optimal mix between pay-as-you-go and funded pension systems: the case of Luxembourg

The funding of the Luxembourg pension system is based on a pay-as-you-go system and hence on an intergenerational contract. As is the case for most other European countries, this system will be exposed to the effects of demographic ageing over the coming decades. The aim of this paper is to develop a model that allows for evaluating the efficiency of a diversified pension system financed partly by a pay-as-you-go scheme and partly by capitalization. The efficiency is measured by the long term sustainability of the system. We compare the sustainability of our model to the one of a pure pay-as-you-go system.
THE USE OF JAZZ CHANTS TO DEVELOP YEAR 3 PUPILS’ ABILITYTO CONSTRUCT SIMPLE SENTENCES

This action research attempts to improve teacher’s classroom teaching in developing pupils’ ability to construct simple sentences. Jazz chanting was adapted to teach writing skills and was used as the intervention. This research aimed to describe the extent the use of jazz chants was able to develop Year 3 pupils’ ability to construct simple sentences effectively. Three research participants were chosen among year 3 pupils. The participants were purposefully identified as they had encountered difficulties in constructing simple sentences. Three lessons to exploit the intervention were conducted in this research. The data collection methods that were used in this research to gain insights into the effectiveness of the teacher’s teaching strategy were document analysis consisting of worksheets and a pre-test and a post-test, observation and a semi-structured interview with the participants. The research findings revealed that the teaching with the use of the intervention, jazz chanting, was able to positively impact two participants in constructing simple sentences effectively.Meanwhile, triangulation of the various data also indicated that the teaching aided by the intervention failed to have the expected impact on one participant. Discussion of the research findings and conclusion had highlighted the researcher’s pertinent reflection and suggestions for further improvement on the intervention and for future research.
Attribute non-attendance in patients' choice of general practitioner appointment

This paper compares various ways of accounting for attribute non-attendance in a model of patients' choice of general practitioner appointment. The methods considered include the endogenous attribute attendance model, which is a variant of the equality-constrained latent class model, and various forms of mixed logit models with parametric and non-parametric coefficient distributions. It is found the the willingness to pay estimates derived from the models allowing for attribute non-attendance are considerably lower than those derived from a standard logit model.
Labor market policy: Flexicurity, unemployment, and worker satisfaction

“Flexicurity” is an approach to protecting workers that de-links workers’ protections from the employee-employer relationship. This paper develops two labor policy indices, one measuring the government-provided safety net and another measuring dismissal protection. Flexicurity advocates argue that dismissal protection and other protections delivered through the worker-employer relationship distort firms’ employment decisions and lead to longer unemployment duration while government benefits also protect workers but without distorting firms’ decisions. Flexicurity critics argue that employer-provided protections do not have these side effects and that job security and worker satisfaction are valid policy goals that cannot be met by generous safety nets alone. The indices are used to test these claims. First, they are used with data from the Luxembourg Income Study data to examine policy’s impact on workers’ employment status. Then the they are used with data from the World Values Survey to predict workers’ life satisfaction and happiness, with a particular focus on the unemployed. Findings suggest that in terms of employment effects, dismissal protection and safety nets need to be balanced as to not disproportionately favor one sector of the work force over another. The second analysis finds that a flexicurity policy does seem to be optimal in terms of life satisfaction and happiness, and that if strong employer-provided protections are pursued, they should be accompanied by a generous social safety net and active labor market policies.
DENSE 3D POINT CLOUD GENERATION FROM UAV IMAGES FROM IMAGE MATCHING AND GLOBAL OPTIMAZATION

Abstract. 3D spatial information from unmanned aerial vehicles (UAV) images is usually provided in the form of 3D point clouds. For various UAV applications, it is important to generate dense 3D point clouds automatically from over the entire extent of UAV images. In this paper, we aim to apply image matching for generation of local point clouds over a pair or group of images and global optimization to combine local point clouds over the whole region of interest. We tried to apply two types of image matching, an object space-based matching technique and an image space-based matching technique, and to compare the performance of the two techniques. The object space-based matching used here sets a list of candidate height values for a fixed horizontal position in the object space. For each height, its corresponding image point is calculated and similarity is measured by grey-level correlation. The image space-based matching used here is a modified relaxation matching. We devised a global optimization scheme for finding optimal pairs (or groups) to apply image matching, defining local match region in image- or object- space, and merging local point clouds into a global one. For optimal pair selection, tiepoints among images were extracted and stereo coverage network was defined by forming a maximum spanning tree using the tiepoints. From experiments, we confirmed that through image matching and global optimization, 3D point clouds were generated successfully. However, results also revealed some limitations. In case of image-based matching results, we observed some blanks in 3D point clouds. In case of object space-based matching results, we observed more blunders than image-based matching ones and noisy local height variations. We suspect these might be due to inaccurate orientation parameters. The work in this paper is still ongoing. We will further test our approach with more precise orientation parameters.

THE REDOX PATHWAY OF Pseudomonas aeruginosa CYTOCHROME C BIOGENESIS

Cytochrome c contains heme covalently bound to the polypeptide chain through two thioether bonds between the heme vinyl groups and the two cysteines of the conserved heme- binding motif of the apoprotein. Surprisingly, the biochemical events leading to the synthesis of the functional holoprotein in the cell are largely unknown. In the human pathogen Pseudomonas aeruginosa, the biogenesis of Cytc is mediated by a group of membrane or membrane-anchored proteins (CcmABCDEFGHI), exposing their active site to the periplasm. The Ccm proteins involved in the necessary reduction of apoCyt disulfide bond are CcmG and CcmH. Here we present the structural and functional characterization of these two redox-active proteins. We determined the crystal structure of CcmG, both in the oxidized and the reduced state. CcmG is a membrane-anchored thioredoxin- like protein acting as a mild reductant in the redox pathway of Cytc biogenesis. The 3D structure of the soluble periplasmic domain of CcmH revealed that it adopts a peculiar three-helix bundle fold that is different from that of canonical thiol-oxidoreductases. Moreover, we present protein-protein interaction experiments aiming at elucidating the molecular mechanism of the reduction of apoCyt disulfide bond for heme attachment in vivo. On the basis of the structural and functional data on CcmG, CcmH and their interactions, we propose an assembly line for Cytc biogenesis in P. aeruginosa in which reduced CcmH specifically recognizes, binds and reduces oxidized apoCyt via the formation of a mixed disulfide complex, which is subsequently resolved by CcmG.
Identification of (CdSe) 32 structure in microemulsion-based synthesis

We investigated the optical and physical properties of different ratio of (i) non-ionic sucrose ester S1670 surfactant, (ii) 1-heptanol and (iii) deionized water using polarizing optical microscope. Three stable phases have been identified; they are (i) lamellar phase lyotropic liquid crystal, (ii) microemulsion and (iii) emulsion. CdSe quantum dots (QDs) were successfully synthesized using microemulsion system consisting 40/50/10 weight % of surfactant, oil and water respectively. The extracted QDs were characterized using XRD, UV-Visible and photoluminescence spectroscopies, and transmission electron microscopy (TEM). A thermodynamically stable chemical structure of (CdSe)32 has been identified using first principle density functional theory (DFT) and emitting states of the structure was calculated.

Strategies of literary translation

Literary translation includes a wide range of activities that deal not only with fiction or poetry but also with popular science essays, newspaper articles, diaries, memoirs, etc. These different kinds of texts presuppose different strategies and criteria of translation processing. The unified approach is to consider them integrally as nonstrictly determined translation opposed to strictly determined documentary translation. The difference between the two manifests itself mainly in the proportion of overt and covert regulations and criteria for the choice of equivalents. Literary translation is a covertly regulated process, which is connected with a number of complications, i.e. personal nature of texts under translation (authorship); unspecified audience; interlingual and intercultural inequality; and some others. The lack of systemic criteria determines the use of intuitive choices, such as observer-, helper- or enlightener-strategy.
TITLE: Preliminary genetic evidence of two different populations of Opisthorchis viverrini in Lao PDR AUTHORS: Opal Pitaksakulrat,

Opisthorchis viverrini is a major public health concern in Southeast Asia. Various reports have suggested that this parasite may represent a species complex, with genetic structure in the region perhaps being dictated by geographical factors and different species of intermediate hosts. We used four microsatellite loci to analyze O. viverrini adult worms originating from six species of cyprinid fish in Thailand and Lao PDR. Two distinct O. viverrini populations were observed. In Ban Phai, Thailand, only one subgroup occurred, hosted by two different fish species. Both subgroups occurred in fish from That Luang, Lao PDR, but were represented to very different degrees among the fish hosts there. Our data suggest that, although geographical separation is more important than fish host specificity in influencing genetic structure, it is possible that two species of Opisthorchis, with little interbreeding, are present near Vientiane in Lao PDR.
Left/right asymmetry in Dyakonov–Tamm-wave propagation guided by a topological insulator and a structurally chiral material

The propagation of Dyakonov–Tamm waves guided by the planar interface of an isotropic topological insulator and a structurally chiral material, both assumed to be nonmagnetic, was investigated by numerically solving the associated canonical boundary-value problem. The topologically insulating surface states of the topological insulator were quantitated via a surface admittance γ TI , which significantly affects the phase speeds and the spatial profiles of the Dyakonov–Tamm waves. Most significantly, it is possible that a Dyakonov–Tamm wave propagates co-parallel to a vector u in the interface plane, but no Dyakonov–Tamm wave propagates anti-parallel to u . The left/right asymmetry, which vanishes for γ TI = 0 , is highly attractive for one-way on-chip optical communication.
A case-control study to identify a genetic component contributing to wet carcass syndrome in sheep

Wet carcass syndrome (WCS) is a condition predominantly found in lambs which negatively affects the quality of carcasses. During the pre-slaughter period, the animal appears to be clinically normal, showing no symptoms of an abnormality. However, after slaughter and removal of the skin the carcass appears to be “wet”. The condition is described phenotypically as a subcutaneous accumulation of watery fluid. Therefore, the objective of this investigation was to scan the genomes of afflicted and unafflicted lambs in search of putative quantitative trait loci associated with the WCS phenotype in sheep. Muscle samples from lamb carcasses (43 afflicted and 41 unafflicted) were collected from three different slaughterhouses in the Northern Cape Province of South Africa and Southern Namibia. To test for an association between the phenotype (WCS) and an autosomal genetic marker, a case-control study design was implemented. Separate analyses for each sex were motivated by individual SNP on the X chromosome being suggestive of a QTL. These analyses revealed significant associations between SNP and WCS in males, but not in females. The three SNPs reaching genome-wide significance in males are in strong linkage disequilibrium (LD) with the HTR2C and TENM1 genes.
Using hemispherical photography for estimating photosynthetic photon flux density under canopies and in gaps in Douglas-fir forests of the Pacific Northwest

Our primary objective in this study was to determine if hemispherical (fish-eye) photographs could be used to estimate photosynthetic photon flux density (PPFD) in mature and old-growth Pseudotsuga–Tsuga forests in the Oregon and Washington Cascade Range. LI-COR quantum sensors sampled PPFD at 10-s intervals at six points in each of two old-growth stands from January to December of 1991. Direct measures of PPFD were also made with photodiodes, which were calibrated against quantum sensors. They were used to sample PPFD for 6- to 14-day periods during the summer at 15 points in each of four stands, two mature and two old growth. Hemispherical photographs were taken at these sample points and were digitized and analyzed using the program CANOPY. The software predicts overall site openness and openness along the sun path. Regression models were developed based upon those parameters. The models predicted the mean daily PPFD for each month of the year. Two major factors were found that influenced regression mo.
Nonlinear Luttinger liquid: Exact result for the Green function in terms of the fourth Painlevé transcendent

We show that exact time dependent single particle Green function in the Imambekov-Glazman theory of nonlinear Luttinger liquids can be written, for any value of the Luttinger parameter, in terms of a particular solution of the Painlev\'e IV equation. Our expression for the Green function has a form analogous to the celebrated Tracy-Widom result connecting the Airy kernel with Painlev\'e II. The asymptotic power law of the exact solution as a function of a single scaling variable $x/\sqrt{t}$ agrees with the mobile impurity results. The full shape of the Green function in the thermodynamic limit is recovered with arbitrary precision via a simple numerical integration of a nonlinear ODE.
Thehp finite element method for singularly perturbed problems in nonsmooth domains

We consider the numerical approximation of singularly perturbed elliptic boundary value problems over nonsmooth domains. We use a decomposition of the solution that contains a smooth part, a corner layer part and a boundary layer part. Explicit guidelines for choosing mesh-degree combinations are given that yield finite element spaces with robust approximation properties. In particular, we construct an hp finite element space that approximates all components uniformly, at a near exponential rate. c © 1999 John Wiley & Sons, Inc.

Analysis of morphological traits of bird's foot trefoil plants cv. Bokor transformed with Agrobacterium rhizogenes

An efficient method for genetic transformation and shoot regeneration was achieved in bird's foot trefoil cv. Bokor using A. rhizogens. The transformed shoots were regenerated on hairy root segments in high frequency. After rooting and acclimation, transformed To plants were grown in experimental field. Analysis of morphological traits and chemical content in ten unintentionally chosen To bird's foot trefoil plants (genotypes no. 2 and no. 5) was performed. They were compared to those of control non-transformed plants. The traits as a number of stems per plant, length of internodes in longest stem, number of flowers per plant and plan high were very significant differed than the same traits in control plants, while there were no significant differences in the leaf area. No signs of the rol genes genotype and "T" phenotype were present. The transformed plants had significantly higher content of cellulose, while the protein and nitrogen contents of are in the range of control plants.
Contribution OXYGEN FREE RADICALS MEDIATE THE INDUCTION OF MANGANESE SUPEROXIDE DISMUTASE GENE EXPRESSION BY TNF-a

In this study, the hypothesis that oxygen free radicals act as intracellular messengers is examined. Treatment of human oral carcinoma SCC-25 cells with 200 ng/ml human TNFa for 6 h greatly increased manganese superoxide dismutase (MnSOD) gene expression as detected by western blotting, RT-PCR, and nuclear run-on experiments. In the presence of the oxygen free radical spin trapping reagent, 5,5-dimethyl pyrrolineN-oxide (DMPO), the induction of MnSOD gene expression by TNFa was significantly reduced. Electron paramagnetic resonance experiments showed that the production of oxygen free radicals was enhanced in TNFa treated cells. Taken together, these observations suggest that the induction of MnSOD expression by TNFa is at least partially mediated by intracellular formation of oxygen free radicals, and that superoxide is most likely the initiating species involved in the mediation of MnSOD gene expression by TNFa. © 2000 Elsevier Science Inc.
