Laboratory surveillance of communicable diseases : enteric pathogens

Laboratories represent a crucial link in the surveillance chain. Since only a small proportion of cases of enteric infections are asked to submit a stool sample, one needs to assess the practices for testing for enteric pathogens and their notification practices. Five local laboratories participated in this study. This included a description of the laboratory practices; capacity for stool sample analysis; awareness of the notification system and the factors which could improve the system at laboratory level.

Effectiveness of the Vietnamese Good Agricultural Practice (VietGAP) on plant growth and quality of Choy Sum (Brassica rapa var. Parachinensis) in Northern Vietnam

In response to the recent concerns about human health, ecosystem sustainability and thus demands for food safety, production of clean produce, particularly daily-consumed vegetables, is essential. The study was carried out in Thai Nguyen city (northern Vietnam) during August – November 2011 to evaluate impacts of a VietGAP guideline on plant growth and quality of Choy Sum, one of the major vegetables in the research area. The experiment comprised two treatments, a control (local farmers’ conventional practice) and an experimental treatment (plants grown according to the VietGAP guideline). Plant samples of the latter treatment were collected for quality test at the end of the experiment. Results showed that the experimental plants had significant higher growth parameters with regards to leaf areas (7.13 dm 2 ) and average top plant weight (3.33 kg m -2 ), while those of the control treatment were 5.80 dm 2 and 2.77 kg m -2 , respectively. Lab test results showed the experimental plant samples met the national quality standards to be certified as a clean product. The participatory on-field experiment would facilitate critical reflections, transformative learning and readiness for adoption of eco-friendly production practices by the local farmers
Examples of Möbius-like groups which are not Möbius groups

In this paper we give two basic constructions of groups with the following properties: (a) G ↪→ Homeo+(S), i.e., the group G is acting by orientation preserving homeomorphisms on S1; (b) every element of G is Möbius-like; (c) L(G) = S1, where L(G) denotes the limit set of G; (d) G is discrete; (e) G is not a conjugate of a Möbius group. Both constructions have the same basic idea (inspired by Denjoy): we start with a Möbius group H (of a certain type) and then we change the underlying circle upon which H acts by inserting some closed intervals and then extending the group action over the new circle. We denote this new action by H. Now we form a new group G which is generated by all of H and an additional element g whose existence is enabled by the inserted intervals. This group G has all the properties (a) through (e).
Aerodynamic Thrust Modelling in Wave Tank Tests of Offshore Floating Wind Turbines Using a Ducted Fan

Wave tank testing of scaled models is standard practice during the development of floating wind turbine platforms for the validation of the dynamics of conceptual designs. Reliable recreation of the dynamics of a full scale floating wind turbine by a scaled model in a basin requires the precise scaling of the masses and inertias and also the relevant forces and its frequencies acting on the system. The scaling of floating wind turbines based on the Froude number is customary for basin experiments. This method preserves the hydrodynamic similitude, but the resulting Reynolds number is much lower than in full scale. The aerodynamic loads on the rotor are therefore out of scale. Several approaches have been taken to deal with this issue, like using a tuned drag disk or redesigning the scaled rotor. This paper describes the implementation of an alternative method based on the use of a ducted fan located at the model tower top in the place of the rotor. The fan can introduce a variable force that represents the total wind thrust by the rotor. A system controls this force by varying the rpm, and a computer simulation of the full scale rotor provides the desired thrust to be introduced by the fan. This simulation considers the wind turbine control, gusts, turbulent wind, etc. The simulation is performed in synchronicity with the test and it is fed in real time by the displacements and velocities of the platform captured by the acquisition system. Thus, the simulation considers the displacements of the rotor within the wind field and the calculated thrust models the effect of the aerodynamic damping. The system is not able currently to match the effect of gyroscopic momentum. The method has been applied during a test campaign of a semisubmersible platform with full catenary mooring lines for a 6MW wind turbine in scale 1/40 at Ecole Centrale de Nantes. Several tests including pitch free decay under constant wind and combined wave and wind cases have been performed. Data from the experiments are compared with aero-servo-hydro-elastic computations with good agreement showing the validity of the method for the representation of the scaled aerodynamics. The new method for the aerodynamic thrust scaling in basin tests is very promising considering its performance, versatility and lower cost in comparison with other methods.
Air Compression Performance Improvement via Trajectory Optimization: Experimental Validation

In an isothermal compressed air energy storage (CAES) system, it is critical that the high pressure air compressor/expander is both efficient and power dense. The fundamental trade-off between efficiency and power density is due to limitation in heat transfer capacity during the compression/expansion process. In our previous works, optimization of the compression/expansion trajectory has been proposed as a means to mitigate this tradeoff. Analysis and simulations have shown that the use of optimized trajectory can increase power density significantly (2-3 fold) over ad-hoc linear or sinusoidal trajectories without sacrificing efficiency especially for high pressure ratios. This paper presents the first experimental validation of this approach in high pressure (7bar to 200bar) compression. Experiments are performed on an instrumented liquid piston compressor. Correlations for the heat transfer coefficient were obtained empirically from a set of CFD simulations under different conditions. Dynamic programming approach is used to calculate the optimal compression trajectories by minimizing the compression time for a range of desired compression efficiencies. These compression profiles (as function of compression time) are then tracked in a liquid piston air compressor testbed using a combination of feedforward and feedback control strategy. Compared to ad-hoc constant flow rate trajectories, the optimal trajectories double the power density at 80% efficiency or improve the thermal efficiency by 5% over a range of power densities.
The lexical-grammatical dichotomy in Functional Discourse Grammar

This paper deals with the lexical-grammatical distinction in Functional Discourse Grammar (FDG), addressing such issues as the nature of linguistic categorization (strict versus gradual) and the possibility of representing gradience in underlying representation. It will be shown that both FDG and its predecessor, Functional Grammar (FG), are ambivalent with regard to the lexical-grammatical distinction. On the one hand, both models seem to accept the possibility of strict categorization, making ‘a rather sharp distinction between lexical (or content) elements and grammatical (or form) elements in the structure of linguistic expressions’ (DIK, 1997, p.159), whereby lexical elements are captured by predicates and grammatical elements are analysed as operators or functions. At the same time, however, it is implicitly accepted that categorization is not always an all-or-nothing affair (e.g. DIK, 1997, p.194). The aim of the present paper is, first, to resolve this ambivalence by offering an inventory of criteria (pragmatic, semantic, morphosyntactic and phonological) for the classification of (English) linguistic elements as lexical or grammatical. Secondly, it is argued that, although both distinctions are useful and justifiable, there is no one-to-one relationship between the lexical-grammatical dichotomy and the distinction between predicates and operators/functions. Finally, a proposal is made for an FDG-representation of a particular group of linguistic elements (including pronouns, demonstratives, numerals and prepositions) which do not clearly belong to either category but combine lexical and grammatical features.
The asymmetric geospace as displayed during the geomagnetic
storm on August 17, 2001

Abstract. Previous studies have shown that conjugate auroral features are displaced in the two hemispheres when the interplanetary magnetic field (IMF) has a transverse (Y) component. It has also been shown that a BY component is induced in the closed magnetosphere due to the asymmetric loading of magnetic flux in the lobes following asymmetric dayside reconnection when the IMF has a Y component. The magnetic field lines with azimuthally displaced footpoints map into a banana shaped convection cell in one hemisphere and an orange shaped cell in the other. Due to the Parker spiral our system is most often exposed to a BY dominated IMF. The dipole tilt angle, varying between ±34 deg, leads to warping of the plasma sheet and oppositely directed BY components in dawn and dusk in the closed magnetosphere. As a result of the Parker spiral and dipole tilt, geospace is most of the time asymmetric. The magnetic storm on August 17, 2001 offers a unique opportunity to study the dynamics of the asymmetric geospace. IMF BY was 20–30 nT and tilt angle was 23 deg. Auroral imaging revealed conjugate features displaced by 3–4 hours magnetic local time. The latitudinal width of the dawnside aurora was quite different (up to 6 deg) in the two hemispheres. The auroral observations together with convection patterns derived entirely from data indicate both dayside, lobe and tail reconnection in the north, but most likely only dayside and tail reconnection in the southern hemisphere. Increased tail reconnection during substorm expansion phase reduces the asymmetry.
Relational, Copula and Verbless Clauses in Rembarrnga

Rembarrnga, a polysynthetic language of Arnhem Land, Northern Territory, Australia, has a range of clauses fitting the type termed copula clauses in earlier typologies by Curnow (1999) and Dixon (2002). These express relationships such as attribution, identity, location and possession between a subject noun phrase (CS) and a complement (CC), which may be a noun phrase, an adjective, a locational expression etc. Existential clauses are similar. In Rembarrnga, many of these clauses have no copula verb, suggesting that the category may be better defined functionally rather than formally, as Halliday (1994) and McGregor (1990, 1992, 1996) do. Most such clauses in Rembarrnga involve juxtaposition of CS and CC. The noun phrase complement (CC) may be inflected for tense and for subject pronoun (CS) like intransitive verbs, though with some differences. Rembarrnga inflected nominals in such clauses can also incorporate nouns between the root and the pronominal prefix, just like verbs. There is a set of inchoative suffixes. Tense inflection for these types shows some similarity with positional verbs. A separate positional verb may also be used as a copula. Some examples show the distinction between characterising (verbless) and situational (with copula verb) types found by McGregor for Gooniyandi (McGregor 1990:308).
Detection and analysis of a locus affecting milk concentration in the US and Israeli dairy cattle populations.

DNA microsatellites were used to detect individual loci affecting economically important quantitative traits in dairy cattle via the granddaughter design. Eighteen US Holstein grandsires and 1555 of their sons were genotyped for 30 genetic markers located on 19 of the 29 bovine autosomes. From 16 to 205 sons were genotyped per family. Of 14,650 son genotypes determined, 77% were informative. The genotype data was matched to the bulls' daughter yield deviations for milk, fat, and protein production, fat and protein percentage, productive life, and somatic cell score. The within-family allele effect was significant at p<0.01 for TGLA263 on chromosome 3, CSRM60 on chromosome 10, and CSSM66 on chromosome 14. TGLA263 and CSSM66 had significant effects on more than one trait, but the effects on fat percent were greatest for both loci. The effect of CSSM66 on fat percent was significant at p<10 . CSSM66 also had a significant -7
On a class of moment problems

Abstract : Consider a class M of probability measures on a measurable space X and measurable functions gi and h on X. In a typical moment problem we want further information on the possible sets of values taken by the integrals micrometers (gj) and micrometers (h) as micrometers runs through M. And the main purpose of the present paper is to develop into more systematic methods certain principles which in special cases have been found effective for handling such moment problems. In Sections 2 through 4 we take up certain frequently occurring moment problems where the class X happens to be convex. In Section 2 the space X can be any locally compact Hausdorff space. For {hj, j epsilon J} as an arbitrary collection (finite or infinite) of lower semicontinuous functions on X, we establish a condition which is both necessary and sufficient for the existence of a regular probability measure micrometer on X satisfying y (hj) less than or equal to nj for all j epsilon J. However, we do assume as a side condition that the hj dominate each other at infinity in a certain weak sense. This domination condition is void when X is compact and nearly so when hj equal to or more than 0.
Value at Risk Forecasting

The purpose of this paper is to investigate whether a dynamic Value at Risk model and high frequency realized volatility models can improve the accuracy of 1-day ahead VaR forecasting beyond the performance of frequently used models. As such, this paper constructs 60 conditional volatility forecasting models. Several extensions of the GARCH model are included, such as the nonlinear and asymmetric models. Moreover, several return distributions are assumed for the error term, in order to allow for more flexible modeling in the tails. A rolling Model Confidence Set is subsequently constructed, ensuring that only models with superior out-of-sample forecasting performance remain. A model averaging technique is applied to the remaining superior models, which generates the dynamic VaR forecasts. Moreover, several extensions of the HAR realized volatility model are included in this paper to forecast VaR. In a series of extensive back tests, this paper finds that the dynamic VaR model produces forecasts which are superior to traditional models and HAR models. The result hold for the 95% VaR, but are even more pronounced for the 99% VaR. The traditional models severely underestimate risk at higher confidence levels, whereas the applied dynamic VaR correctly accounts for it.
Helminth fauna of wild boar in Corsica

To determine the helminth fauna of wild boars, 160 stomachs and intestines, 72 lungs and 58 livers of animals from eight areas in Corsica, have been examined. It is the first study made in this Mediterranean island. The evaluation of the helminthic composition revealed six following species: Dicrocoelium dendriticum (Rudolphi, 1819), larval stage of Echinococcus granulosus (Goeze, 1782), Ascaris suum (Goeze, 1782), Metastrongylus sp. , Globocephalus urosubulatus (Alessandrini, 1909), Macracanthorhynchus hirudinaceus (Pallas, 1781). Differences among prevalence data indicated an overdispersed helminth distribution in Corsica.
RELATIVE REPRESENTATION OF PHEIDOLE ( HYMENOPTERA : FORiWCIDAE ) IN LOCAL GROUND ANT ASSEMBLAGES OF THE AMERICAS

En 195 estudios publicados sobre comunidades de hormigas de suelo de las Américas, la representación faunística de Pheidole fue mayor que la de cualquier otro género. No se encontró una relación significativa entre el porcentaje de la representación faunística y la latitud, pero su representación fue mayor en los trópicos. En cultivos fmctíwlos se detectó un porcentaje mayor de especies de Pheidole que en otros tipos de hábitat. Adicionalmente, el porcentaje de especies de Pheidole relacionó negativamente con el porcentaje de especies de Formicinae. Este efecto fue mayor que la influencia de la latitud sobre Fomicinae. No se encontró una relación negativa significativa entre Pheidole y otros grupos taxonómicos. Este resultado sugiere que las especies de Pheidole pueden competir con las especies de Formicinae, o que estos dos grupos están ubicados en los extremos opuestos de un gradiente de estrés ambiental.
Seasonal migration, vertical activity, and winter temperature experience of Greenland halibut Reinhardtius hippoglossoides in West Greenland waters

The deep-water flatfish Greenland halibut Reinhardtius hippoglossoides (Walbaum) is common along the West Greenland coast. In the northwestern fjords, Greenland halibut is an important socio-economic resource for the Greenland community, but due to the deep and partly ice-covered environment, very little is known about its behavior and habitat characteristics. We tagged adult Greenland halibut in the waters off Ilulissat with electronic data storage tags that collected information on depth, temperature, and time. Although clear differences between individuals in migration and vertical behavior were present, we discovered a consistent seasonal migration from the relatively shallow-water Disko Bay area into the deep waters of the Ilulissat Icefjord, where the fish resided in the winter months before returning to Disko Bay. Vertical activity was pronounced at both locations, with fish covering vertical distances of up to 100 m within 15 min. During the winter months, the fish experienced temperatures between ca. 0 and 4°C, with most experiencing temperatures of 2 to 3°C. Irrespective of year and quarter of the year, the fish experienced warmer water and a broader range of temperatures when resident in Disko Bay (mean range 2.6°C) than when resident in the ice fjord (mean range 1.4°C). Using the tagged halibut as a 'live tool,' we show that parts of the ice fjord are hundreds of meters deeper than pre- viously thought. We also document the first seawater temperature measurements made beneath the Jakobshavn Isbrae outlet glacier, revealing a positive relationship between depth and temper- ature for the upper 600 m and a between-year variation in temperatures beneath the ice sheet in 2001, 2002, and 2003.

The wage curve: evidence from the Finnish metal industry panel data

In this paper we study the wage curve with Finnish metal industry panel data from the period 1991–95. As an unemployment variable we use the unemployment rate of the regional county. The unemployment rate is split into short- and long-term unemployment. The effect of active labour market policies is controlled for by augmenting the wage equation with a variable for subsidised employment schemes. The estimated unemployment elasticity of wages in the Finnish metal industry is somewhat smaller than the elasticities reported by other studies. Long-term unemployment increases wages and subsidised employment schemes decrease them. Their combined effect is zero. The regional fixed effects estimate of the slope of the wage curve is –0.04. The dependent variable is the logarithm of the fixed hourly wage and the unemployment variable is corrected so that the long-term unemployed are removed from the pool of unemployed and the labour force and the workers in subsidised employment schemes are considered as unemployed. Estimations with regional means indicate that common group errors bias the estimates of standard errors significantly.
Project work as an integrating and revenue-making tool

1. Abstract The Engineering College at Hogskolen i Telemark has since 1982 practised cooperative learning as the model of promoting student learning. It has earlier been shown that the Telemark Model do enhance many important aspects of learning and human growth. However, new demands on higher education in Norway asks for new roles of universities and colleges to make the country competitive also in the future. One of these demands is making revenues. Revenue-making through traditional research activities is well known. The question has been raised, if even the project model can be used to add to the college incomes. In this connection the integrating effects of the Telemark Model might represent a powerful tool even in generating a cashflow into the system. The study shows that there are differences between the departments, and that project work does integrate knowledge with practice. But, even if a large portion of the projects are carried out in cooperation with external partners, the economic impact on the College must be labeled “insignificant” so far. A possible conclusion is that the Telemark Model may represent large and so far almost unused resources for income generation. This can be changed by reducing the ambition of having Main Projects at the traditional “high academic level” and in stead, take advantage of the integrating effects of the Model. It is then thinkable that a redefinition or extension of what “high academic level” really means will be necessary to stimulate the revenues to pour into the School. Maybe the ability to integrate many elements into a project report and presentation within a specified time may represent one solution to that problem?
