HUMAN AND ENVIRONMENTAL INFLUENCES ON PLANT DIVERSITY AND COMPOSITION IN BEN EN NATIONAL PARK, VIETNAM

understand the influence of human disturbance and the physical environment on plant biodiversity in Ben En National Park, Vietnam, we analysed species composition and density in forest plots with diverse soils and varying degrees of human disturbance. Soil factors significantly influenced tree species composition, although they only explained 5.7% of the observed data variance. Human factors (disturbance) were second most important in explaining species composition and density, accounting for 4.4% of variance. Changes in species composition related to human disturbance varied mostly independently of soils. The species composition of slightly and heavily disturbed forest differed significantly, with species of low conservation value being most common in heavily disturbed forest, while endangered species and important timber trees were most common in least disturbed forest. Density of treelets was higher in limestone forest than in non-limestone forest. Timber trees and other useful plant species used for a whole range of non-timber forest products (NTFPs) were more abundant in the less disturbed plots, which were located far away from villages and roads. Basal area in less disturbed forest was also larger than in heavily disturbed forest, indicating that the pressures of illegal logging and harvesting were closely connected to travel distances to nearest villages. Limiting the accessibility to forest resources should therefore be a priority in forest conservation as a first step to safeguard the rich biodiversity and stocks of useful plants in the park.
REPRESENTING CK THEORY WITH AN ACTION LOGIC

CK theory is an interesting and unique theory of design. This paper introduces ALX3d, a formal version of CK based on the action logic ALX3, which is able to represent aspects of the actions, preferences, beliefs, and knowledge of collaborating, imperfect agents (such as human designers). It is shown that all the basic notions of CK can be rendered in the logic of ALX3d with only one relatively minor change in how the CK terms concept and knowledge are defined and related. Beyond this, ALX3d provides a richer framework for describing design activities in formal terms, including alternation between synthesis and analysis tasks, and the definition of goals that trade off design requirements against one another. A case study of CK from is used to show how ALX3d can also be used to describe some 'realworld' situations. The advantages of ALX3d are that they recast CK in a form more readily understood by those accustomed to expert, knowledge-based, and formal systems; provide a 'scientific' vehicle for reasoning about the design activities it can describe; and define a possible basis for the development of new, computer-based designers' aids.
An Investigation into the Effect of Group Play Therapy on Aggression Reduction in Male Preschool Students

The current research aims at investigating the effect of group play on aggression reduction in male preschool students. The population of the study was male preschool students in Mashhad, a city in north east of Iran. Among the preschool centers across the city, one center was randomly chosen for the study, from which thirty students were randomly assigned into two groups of experimental and control. The experimental group would undergo 11 sessions of play therapy. The research benefits from a quasi-experimental pre-test post-test design with descriptive, prescriptive and co-variance analysis for interpreting the data. The results of the study indicate that play therapies reduced the amount of aggression on children to a large extent. Thus, a comparison of the results of pre-test with the post-test indicates a meaningful difference at the p<0.05 degree of freedom, suggesting that group play therapy can reduce the preschool children’s aggression.
Identification of metal-tolerant organisms isolated from the Plankenburg River, Western Cape, South Africa

The ability of biofilms to resist pollutants makes them advantageous for use in bioremediation. The objective of this investigation was to isolate metal-tolerant micro-organisms from a site along the Plankenburg River. Microbial biofilms cultivated in multi-channelled flow cells were exposed to varying concentrations of aluminium (Al), iron (Fe), copper (Cu), manganese (Mn), nickel (Ni) and zinc (Zn), stained with the BacLight TM viability probe, visualised using epifluorescence microscopy and analysed using ScionImage. Exposure to the highest Al, Fe, Cu and Mn concentrations increased the percentages of dead cells. A difference in live and dead cells after exposure to varying Zn and Ni concentrations was not evident. When exposed to the lowest concentrations, no notable difference could be detected in comparison with the untreated control. Possible metal-tolerant micro-organisms were identified from the exposed flow cells using polymerase chain reaction (PCR) and deoxyribonucleic acid (DNA) sequencing, followed by ClustalX alignment and phylogenetic analysis. Phylogenetic analysis identified a variety of organisms, including Bacillus sp. , Pseudomonas sp. , Delftia tsuruhatensis strain A90, Kocuria kristinae strain 6J-5b, Comamonas testosteroni WDL7, Stenotrophomonas maltophilia strain 776, Staphylococcus sp. MOLA:313, Micrococcus sp. TPR14, Sphingomonas sp. 8b-1 and Microbacterium sp. PAO-12. Two major clusters could be distinguished based on their Gram-reactions. Keywords: BacLight TM viability probe, biofilms, phylogenetic analysis, river water, ScionImage

Large-scale live imaging of adult neural stem cells in their endogenous niche

Live imaging of adult neural stem cells (aNSCs) in vivo is a technical challenge in the vertebrate brain. Here, we achieve long-term imaging of the adult zebrafish telencephalic neurogenic niche and track a population of >1000 aNSCs over weeks, by taking advantage of fish transparency at near-infrared wavelengths and of intrinsic multiphoton landmarks. This methodology enables us to describe the frequency, distribution and modes of aNSCs divisions across the entire germinal zone of the adult pallium, and to highlight regional differences in these parameters. Summary: This methodology permits long-term imaging and tracking of NSCs in the adult zebrafish telencephalic neurogenic niche, allowing the frequency, distribution and modes of NSC divisions to be analyzed.
A research roadmap for evacuation models used in fire safety engineering

Evacuation models used in fire safety engineering have largely expanded their capabilities over the last decades. They started as simple computational tools in which people movement equations were implemented in discrete spaces, while they now often allow the simulation of complex behaviours and decision making through advanced agent-based simulation techniques in three-dimensional environments. While the progress of evacuation modelling techniques appears evident comparing their capabilities over the years, there are still quite a few areas in which there is room for significant improvements. This paper wants to open a discussion on a research roadmap for evacuation models used in fire safety engineering. In other words, this paper explores what features need to be possibly implemented, improved, or expanded in existing evacuation models for fire safety engineering applications. This considers both improvements based on existing knowledge in the evacuation research field as well as possible future research directions. Five areas of development concerning evacuation modelling are here discussed, namely 1) factors affecting people movement, 2) route choice modelling, 3) behavioural uncertainty, 4) integration with other models and 5) validation methods.

Study of the Physical Properties of Cobalt/ Cobalt Oxide Particles Synthesized by Pulsed Laser Ablation in Different Liquid Media

This work is devoted to the production of microparticles via pulsed laser ablation from a solid cobalt target immersed in three different solutions of distilled water as well as in ethanol and in acetone, to study the effect of liquid media on the physical properties and structure of particles. The samples were characterized using XRD, SEM and particle size analysis. More than simply Co particles have resulted in each three liquid media, CoO particles were produced only in acetone, whereas Co3O4 particles were predominantly produced in water and ethanol.
Searching for supernovae in the multiply-imaged galaxies behind the gravitational telescope A370

Aims. Strong lensing by massive galaxy clusters can provide magnification of the flux and even multiple images of the galaxies that lie behind them. This phenomenon facilitates observations of high-redshift supernovae (SNe) that would otherwise remain undetected. Type Ia supernovae (SNe Ia) detections are of particular interest because of their standard brightness, since they can be used to improve either cluster lensing models or cosmological parameter measurements. Methods. We present a ground-based, near-infrared search for lensed SNe behind the galaxy cluster Abell 370. Our survey was based on 15 epochs of J-band observations with the HAWK-I instrument on the Very Large Telescope (VLT). We use Hubble Space Telescope (HST) photometry to infer the global properties of the multiply-imaged galaxies. Using a recently published lensing model of Abell 370, we also present the predicted magnifications and time delays between the images. Results. In our survey, we did not discover any live SNe from the 13 lensed galaxies with 47 multiple images behind Abell 370. This is consistent with the expectation of 0.09 ± 0.02 SNe calculated based on the measured star formation rate. We compare the expectations of discovering strongly lensed SNe in our survey and that performed with HST during the Hubble Frontier Fields (HFF) programme. We also show the expectations of search campaigns that can be conducted with future facilities, such as the James Webb Space Telescope (JWST) or the Wide-Field Infrared Survey Telescope (WFIRST). We show that the NIRCam instrument aboard the JWST will be sensitive to most SN multiple images in the strongly lensed galaxies and thus will be able to measure their time delays if observations are scheduled accordingly.
Average circulation, seasonal cycle, and mesoscale dynamics of the Peru Current System: A modeling approach

H isolines. The PCCC appears to be directly forced by the cyclonic wind stress curl. The model is able to produce the upwelling front, the cold water tongue which extends toward the equator and the equatorial front as described in the literature. Model seasonal changes in SST and SSH are compared to measurements. For the central PCS, model EKE is 10% to 30% lower than the observations. The model eddy diameters follow a strong equatorward increase. The injection length scales, derived from the energy spectra, strongly correlate to the Rossby radius of deformation, confirming the predominant role of baroclinic instability. At 3� S, the model solution appears to switch from a turbulent oceanic regime to an equatorial regime dominated by zonal currents.
Numerical Study of Horizontal Centrifugal Casting of Rolls

A numerical model was proposed to simulate casting of an outer shell of a work roll made by the horizontal centrifugal casting (HSC) technique. The present paper is focused on the mathematical description of the average flow dynamics of the liquid metal spreading inside the horizontally rotating mold. Later, we will target on the simulation of the whole casting process (~35 min) which requires an extremely efficient flow algorithm. Therefore, the 2D shallow water equations (SWE) were adopted and modified omitting the momentum in the radial direction and taking into account forces such as the centrifugal force, the Coriolis force, the gravity force, the bed shear force, the shear force due to turbulent effects, the wind shear force, and forces arising from the spatially variable topography. The variable topography will later represent the solidifying liquid/solid interface. An approximate Riemann solver was developed using the standard and corrected Roe averages. Each wave was upwinded using the Godunov’s method. The High Resolution corrections (HR) were applied using flux limiters (MC) to keep possible sharp discontinuities in the solution. Transonic waves leading to the expansion shocks were prevented by an extra degree of freedom giving the algorithm a natural entropy fix. All source terms were physically bounded and well-balanced for steady states (producing nonoscillatory solutions). The well-balancing is shown on 1D examples. The effect of forces on the shape of collapsing parabola is shown in 1D in the circumferential direction. Steady state profiles of the liquid height under action of the gravity are discussed for the cases with initially uniform liquid height and a hump in the topography.
Enterprise Architecture Ontology for Services Computing

Enterprise services computing is the current trend for powerful large-scale information systems, which increasingly converge with cloud, computing environments. In this paper, we propose an original ontology-based Architecture Classification Framework for supporting cyclic architecture evaluations and optimizations of enterprise systems based on service-oriented architectures: ESARC - Enterprise Services Architecture Reference Cube. ESARC provides a standardized and normative classification framework for important architecture artifacts of service-oriented enterprise systems. Current approaches for assessing architecture quality and maturity of service-oriented enterprise software architectures are rarely validated and were intuitively developed, having sparse reference model, pattern, metamodel, or ontology foundation. Cyclic assessments of complex service-oriented systems and architectures should produce comparable evaluation results. Today architecture evaluation findings are hardly comparable. Our current idea and contribution is to extend the basic architecture classification framework of ESARC from our previous research by developing specialized metamodels and ontologies for a coherent set of reference architectures, to be able to support machine-based architecture diagnostics and optimizations in enterprise services computing.
The relationship between body condition score and backfat in gestating sows

Backfat and body condition score were measured on 731 sows in a commercial swine facility to assess the accuracy of feeding sows in gestation based on body condition score. Body condition score was poorly correlated (r = 0.19) with backfat thickness. For example, sows assessed with a body condition of 3 ranged in backfat from 0.3 to 0.9 in. (7.5 to 23 mm). This illustrates the need to find a more objective method of measuring body condition (such as ultrasound) in order to properly adjust feeding levels and thus reduce variation in backfat of sows.
Spillovers in a decentralized health economy

We estimate the direct as well as the spillover effect of a federal grant (Municipalities’ Participation Fund, FPM)) on local health indicators in Brazilian municipalities. We use a Regression Discontinuity Design (RDD) when exploring the FPM distribution rule according to population brackets, and we disentangle each effect considering neighbouring towns near different thresholds. Our quasi-experimental estimates show that the FPM spillovers improve local health indicators but reduce the provision of public goods, especially when the neighbouring municipality receiving the additional transfer is small. In particular, our results show that the decentralization of health services could lead to an under-provision of health services in terms of the number of doctors (-0.35% and -0.87%, respectively, for cities with smaller populations), especially general practitioners and surgeons (-1.84% and -2.45%, for the most populous cities in our sample). At the same time, the direct effect is positive as expected, particularly in the Family Health Programme — the main preventive programme in small towns — where there is an increase in PSF visits (1.59%) and PSF visits with a doctor (1.8%) or a nurse (2%). We also find positive effects on hospitalization and complex services in the major cities in the sample and reductions in the infant mortality rate (-0.18%) and morbidity rate (-0.41%). The direct impacts are reduced when we control for neighbours’ FPM, which shows that the spillover effects and spatial interactions are important for explaining the FPM effect on health outcomes. We test whether the negative spillovers are caused by the lack of policy coordination among neighbouring cities, aside from the reduction in regional demand for health services. We find that the spillover effects are stronger when there is more competition in mayoral elections and when neighbouring mayors are not from the same party, which shows that political incentives are important for explaining the observed spillovers.
On matrix-driven failure in unidirectional NCF composites - A theoretical and experimental study

With ever increasing traffic levels, the civil aircraft industry is in constant need of new technologies to make air travel environmentally sustainable. One such technology is light materials to reduce the energy consumption in flight. Currently, up to 53 weight percent of the Airbus A350XWB aircraft is made from carbon fibre reinforced polymer (CFRP) material, mainly in the fuselage and wings. There are other areas in the aircraft where components traditionally made from metals can be replaced with composite material, for instance the cold and moderately high temperature parts of the engines. CFRP fanblades were successively introduced in a civil aircraft engine (GE90) in 1994 and there is now an interest to increase the use of CFRP deeper into the engine. The current research project is carried out in response to an industrial need of cost-effective CFRP components in load carrying parts of the engine. The preferred route is an automated, out-of-autoclave manufacturing method using resin transfer moulding (RTM) with a non crimp fabric (NCF) as reinforcement. Carbon fibre/Epoxy composites reinforced with NCF offer potential cost savings over tape based prepreg materials, with good mechanical properties - close to that of prepreg type composites. For this reason, NCF-reinforced composites provide an interesting alternative to prepregs for the aerospace industry. One limiting factor for their use in primary structures is their relatively low strength in compression. The overall goal of this research project is to further understand the compressive behaviour of NCF composites and to develop a strength assessment method for the aerospace industry. In the first part of the project, we increase the fundamental understanding of the composite material on a meso-scale level, where the NCF have a specific architecture, consisting of fibre tows in various configurations. A new failure criterion has been developed to take into account the orthotropic properties in the transverse (2-3) plane. Local interaction between two bundles out-of-plane was simulated with a finite element model and it was proved to be one possible explanation for the reduced strength out-of-plane. In the second part of the thesis, we investigate the influence of intrinsic material variations on the performance of an NCF composite loaded in compression. These intrinsic variations to the material have been identified as potentially likely to occur in future aero-engine composite structures. In conjunction with the compression test campaign, a method to measure fibre misalignment angles out-of-plane has been developed based on microscopy and a Matlab script. The fibre waviness was found to have a strong adverse effect on the compressive stiffness and strength of the material. The measured compressive strength was reduced to half when the mean fibre misalignment angle was doubled.
Atmospheric studies of habitability in the Gliese 581 system

Context. The M-type star Gliese 581 is orbited by at least one terrestrial planet candidate in the habitable zone, i.e. GL 581 d. Orbital simulations have shown that additional planets inside the habitable zone of GL 581 would be dynamically stable. Recently, two other planet candidates have been claimed, one of them in the habitable zone. Aims. In view of the ongoing search for planets around M stars that is expected to result in numerous detections of potentially habitable super-Earths, we take the GL 581 system as an example for investigating such planets. In contrast to previous studies of habitability in the GL 581 system, we use a consistent atmospheric model to assess surface conditions and habitability. Furthermore, we performed detailed atmospheric simulations for a much larger subset of potential planetary and atmospheric scenarios than previously considered. Methods. A 1D radiative-convective atmosphere model was used to calculate temperature and pressure profiles of model atmospheres, which we assumed to be composed of molecular nitrogen, water, and carbon dioxide. In these calculations, key parameters such as surface pressure and CO2 concentration, as well as orbital distance and planetary mass are varied. Results. Results imply that surface temperatures above freezing could be obtained, independent of the atmospheric scenarios considered here, at an orbital distance of 0.117 AU. For an orbital distance of 0.146 AU, CO2 concentrations as low as 10 times the present Earth’s value are sufficient to warm the surface above the freezing point of water. At 0.175 AU, only scenarios with CO2 concentrations of 5% and 95% were found to be habitable, so an additional super-Earth planet in the GL 581 system in the previously determined dynamical stability range would be considered a potentially habitable planet.
Porting the WRF Model to EumedGrid and Simulation of Air Quality in Urban Zones

The Grid platforms used for this study are MaGrid and EumedGrid. MaGrid is linked to EumedGrid, and users can have access to appropriate CPU and storage resources. The Grid Computing abundant resources enable multiple scenarios to run in parallel, and the MPI parallel programming model allows execution time to decrease substantially with increasing the number of Worker Nodes. In addition, for most scenarios’ simulations, numerical grid can be more refined especially in sensitive regions, leading to a higher degree of accuracy in the results.
Robust Face Recognition via Occlusion Detection and Masking

Sparse representation-based classification (SRC) method has demonstrated promising results in face recognition (FR). In this paper, we consider the problem of face recognition with occlusion. In sparse representation-based classification method, the reconstruction residual of test sample over the training set is usually heterogeneous with the training samples, highlighting the occlusion part in test sample. We detect the occlusion part by extracting a mask from the reconstruction residual through threshold operation. The mask will be applied in the representation-based classification framework to eliminate the impact of occlusion in FR. The method does not assume any prior knowledge about the occlusion, and extensive experiments on publicly available databases show the efficacy of the method.
