ENHANCING COORDINATION IN CHICKEN PRODUCTION IN YEN THE DISTRICT, BAC GIANG PROVINCE, VIETNAM

Rapid expansion of chicken production in Yen The district, Bac Giang province has promoted the integration among actors in the commodity chain. The study aims to provide a broad picture of coordination activities in chicken production in the district, and to propose recommendations enhancing the integration. Data was collected from 62 chicken farming households which were analyzed using comparative statistics, i.e. test of means, and logit regression to establish the factors that promote the coordination in poultry production among farmers. Despite the large quantity of chicken supply, there is no formal integration among actors in chicken commodity chain in Yen The. Instead, poultry farms have established production groups among themselves– called chicken farming group, with activities based mostly on verbal contracts. Smallholders in chicken farming who joined the groups perceived economic benefits, capacity building, and even spiritual supports among members. Income generated from chicken farming (per kg of liveweight chicken) is higher for farmers in chicken farming group than that of independent holders. Key factors affecting the coordination in chicken production are (i) smallness of the scale of production (related with unreliable supply), (ii) absence of services providers who are willing to coordinate with farmers, (iii) problems during implementation of contracts and (iv) the lack of an enabling environment for coordination. Recommendations for enhancing coordination between farmers and other actors in chicken commodity chain were proposed accordingly, focusing on the strengthen of current CGG and formation of new groups, training for chicken growers, legal supports for coordination in the commodity chain, active involvement of researchers and banks, and improvement of veterinary services.
3-D Integrated Geological Modeling in the Abitibi Subprovince (Québec, Canada): Techniques and Applications

The development of robust 3-D geological models involves the integration of large amounts of public geological data, as well as additional accessible proprietary lithological, structural, geochemical, geophysical, and diamond drill hole data. 3-D models and maps have been available, particularly in the petroleum industry, for more than 10 years. Here, we demonstrate how robust 3-D maps can be used as interactive tools for mineral deposits exploration. In particular, we show how the interrogation of 3-D data sets can constrain exploration targets at depth. The main advantages of this technique for the mining industry are the homogeneity of data treatment and the validation of geological interpretations, taking into account geophysical and geochemical data. Data integration and cross-correlation of geology and geophysics can be achieved in two dimensions in any good GIS package. However, the added strength of 3-D analysis is the integration of separate data sets in three dimensions to build more complete, more realistic models, and in delineating areas of high economic potential at depth. Furthermore, these models can be modified and improved at any time by adding new data from ongoing drilling and geoscientific surveys. This paper presents two examples of 3-D models used for mineral exploration: the Joutel VMS mining camp and the Duparquet gold camp, Quebec. In both examples, the creation of the model is discussed and queries specific to the relevant exploration model are introduced. Eight potential exploration targets are generated at Joutel and seven at Duparquet. Although the targets defined are dependent on the details of the chosen queries, it is apparent that this technique has the potential to generate promising exploration activity that can engender new targets. © 2006 Canadian Institute of Mining, Metallurgy and Petroleum.

The Ozone Monitoring Instrument : Overview of thirteen years in space

This overview paper highlights the successes of the Ozone Monitoring Instrument (OMI) on board the Aura 25 satellite spanning a period more than 13 years. Data from OMI has been used in a wide range of applications and research resulting in many new findings. Due to its unprecedented spatial resolution, in combination with daily global coverage, OMI plays a unique role in measuring trace gases important for the ozone layer, air quality, and climate change. With the operational Very Fast Delivery (VFD) (direct readout) and Near Real Time (NRT) availability of the data, OMI also plays an important role in the development of operational services in the atmospheric chemistry domain. 30
Bicyclist behavior analysis for PCS (pre-collision system) based on naturalistic driving

In recent years, automakers have introduced the PCS (Pre-Collision System) which is designed to warn a driver or to brake automatically to help avoid or mitigate accidents. One of the significant aspects of this system is to help protect vulnerable road users such as pedestrians and bicyclists. In this paper, the research is introduced which analyzes normal bicyclist behavior in order to design and evaluate PCS systems. The attributes of normal bicyclist behavior investigated are: TTC (Time-To-Collision), lateral position, vehicle speed and bicycle speed. This behavior was analyzed using TASI’s (IUPUI’s Transportation Active Safety Institute) naturalistic driving data from 110 cars.
Inter-annual rainfall variability and droughts occurrence during sowing and mid-season rice farming calendar in the forest belt of Nigeria

This study examined the trends of rainfall and the intensity of drought during sowing season and mid-season of rice farming calendar in the rainforest belt of Nigeria using data spanning 52 years (1961-2012) for five synoptic weather stations. The trends were investigated using simple linear regression and second order polynomial, while the significance of the trends was evaluated using Pearson's Product Moment Correlation. The drought intensities during the two seasons were computed as percentage derivations from the mean. Rainfall during the sowing season witnessed upward trends in Ondo, Port Harcourt, Benin and Calabar at annual rates of 0.450 mm, 1.005 mm, 3.581 mm and 2.144mm respectively with statistical significance in Benin (0.398, p<0.01) and Calabar (0.295, p< 0.05) while Warri witnessed insignificant decline at an annual rate of -0.525 mm. Rainfall in the midseason witnessed insignificant increase in Warri, Ondo, Port Harcourt and Calabar at annual rates of 0.096 mm, 0.118 mm, 0.172 mm and 0.016 mm respectively. Rain-days declined insignificantly in all the stations during the sowing season with the exception of Port Harcourt which witnessed significant decrease (-0.268, p<0.05) while mid-season rain-days declined in all the stations but only significantly in Warri (-0.301, p<0.05) and Ondo (-0.366, p<0.01). The droughts intensities varied mainly between slight and moderate intensities during the two seasons with pockets of severe and disastrous intensities in Port Harcourt and Warri. It was concluded that rainfall trends was upward in all the stations with the exception of Warri and Benin with declining trends during the sowing season and mid-season respectively while rain-days were decreasing in the two seasons coupled with droughts mainly of slight and moderate intensities. The study suggested an early rainfall forecast and timely irrigation for optimal rice production in the region. Keywords: Rainfall, rain-days, drought, rice, rainforest belt, Nigeria
Is Good Governance Really a Significant Statistical Issue for Current African Economies? The Case of ECOWAS Countries

This study examines the triangular relationship between the flows of foreign direct investments (FDIs), public governance as measured by WGIs (Worldwide Governance Indicators) and economic growth in the 15 countries of the Economic Community of West African States (ECOWAS) between 1996 and 2011. The authors conclude that there is a negative relationship between FDIs and economic growth. More importantly, the effect of public governance was analyzed using the estimated coefficients of the variables voice and accountability, quality of regulation, government effectiveness, political stability and absence of violence, rule of law and corruption control, and the results showed that for half of these indicators, governance contributes negatively to the economic growth of ECOWAS countries.
Phytoevaluation of the nutritional values of ten green leafy vegetables in South -Western Nigeria

Vegetable consumption has been associated with decreased risk of chronic diseases. In this work, ten green leafy vegetables were analysed for basic nutrients in the diet of man with a view to ascertaining their nutritional potentials. Samples of the fresh vegetables collected were separated into two and used in the wet and dry forms. Column chromatographic separation of the ethanol extract of the wet samples showed the protein, carbohydrate and fat contents. Spectrophotometric analysis of dried samples revealed the Calcium, Magnesium, Phosphorous, Iron and vitamin contents. Potassium and Sodium were determined using flame photometry. All the vegetables showed high moisture contents (75.0 – 91.5%). The highest carbohydrate and protein contents of 5.8 and 6.4g/100g respectively, were recorded in Telfairia occidentalis. Ascorbic acid contents were between 28.0 to 410.0mg/100g while vitamin A ranged from 8.00 to 6120 I.U. Potassium is generally the highest in the vegetables while iron is the lowest.

Study on Isolation Improvement Between Closely Packed Patch Antenna Arrays Based on Fractal MTM- Electromagnetic Bandgap Structures

A decoupling metamaterial (MTM) configuration based on fractal electromagnetic bandgap (EMBG) structure is shown to significantly enhance isolation between transmitting and receiving antenna elements in a closely packed patch antenna array. The MTM-EMBG structure is cross-shaped assembly with fractal shaped slots etched in each arm of the cross. The fractals are composed of four interconnected ‘Y-shaped’ slots that are separated with an inverted ‘T-shaped’ slot. MTM-EMBG structure is placed between the individual patch antennas in a 2×2 antenna array. Measured results show the average inter-element isolation improvement in the frequency band of interest is 17 dB, 37 dB and 17 dB between radiation elements #1 & #2, #1 & #3, and #1 & #4, respectively. With the proposed method there is no need for using metallic via-holes. The proposed array covers the frequency range of 8-9.25 GHz for X-band applications, which corresponds to a fractional bandwidth of 14.5%. With the proposed method the edge-to-edge gap between adjacent antenna elements can be reduced to 0. 5λ0 with no degradation in the antenna array’s radiation gain pattern. Across the array’s operating band, the measured gain varies between 4 dBi and 7 dBi, and the radiation efficiency varies from 74.22% and 88.71%. The proposed method is applicable in the implementation of closely packed patch antenna arrays used in multiple-input-multiple-output (MIMO) systems and synthetic aperture radars (SAR).
Masters Thesis: Comparison of Equilibrium-Stage and Rate Based Model of an Absorption Column for a CO2-MEA system

The desorption step of the carbon dioxide absorption/desorption process is an extremely energy intensive process, which accounts for 70% of operating cost according to Mofarahi et al. [2008]. Technip-ECN has proposed a solution of Heat integrated absorption column. In order to develop a model for this new column, an equation based model of the regular absorption column was required to be made where the equations are written in residual form so that the programmer has control over the parameters and equations. In this study, two models of carbon dioxide absorption were developed in PythonTM which represent the two different approaches that exist in literature, namely the rate based model and the equilibrium model. These models are then compared against each other on the basis of their ability to predict experimental data in four varying conditions. The key research question is to find out if the models can predict the temperature bulge inside the absorption column and what factors affect the position and shape of the temperature bulge. The results show that the rate based model gives better predictions as compared to the equilibrium model. The rate based model further reveals that competing absorption and evaporation processes produce the temperature bulge and that the position and shape of the bulge can be changed by changing the extent of absorption and evaporation. It is observed that the results of the rate based model are dependent on the model parameters such as correlations for mass transfer coefficient, enhancement factors, rate constants etc. This model is recommended to be used in the second stage of the project.

The Development of a New Type Rooftop Ventilator Turbine

This paper presents a small power generation system motivated by a coreless stator AFPM (Axial Flux Permanent Magnet) generator which is driven by the rooftop ventilator. The generator consists of discs for the rotor and the stator geometry. The stator disc is sandwiched between two rotor discs and the magnets in the two opposite rotor discs may be placed N-S arrangements. Since there is no silicon steel inside the coils, we should eliminate the magnetic pulling force between the rotors and the stators. When the ventilator rotates, the flux of the permanent magnet rotors part move across the air gap and induces the emf in the coreless coils. After that, the ac voltage is rectified to dc voltage and finally charged to the 12 V 5 Ahr battery for household appliances. To analyze the magnetic circuit, the finite element analysis was used to simulate the magnetic flux density in the AFPM generator. The test is operated in electrical machines laboratory and essentially to determine the characteristics of prototype generator. Based on the experiments, the results of the output voltage can achieve 103 V with no-load, and 20 V on 100 Ω resistive loads at the speed of 200 rpm. For the results after installing the generator on the roof of a building to charge the 12 V battery, the minimum wind speed for enough charging to battery is at 10 rpm. Furthermore, the prototyped of the generator is relatively small and cheap. After the fabrication and testing of the prototype, this system has been proved feasible for practical application.
Dietary crude oil exposure during sexual maturation induces hepatic mixed function oxygenase (CYP1A) activity at very low environmental temperatures in Polar cod Boreogadus saida

Previous studies have indicated that hydrocarbon induction of the hepa t~c microsomal monooxygenase Cytochrome P450 1A (CYPlA) is attentuated in certain species of fish by low temperature and in sexually mature female fish by estradiol. This enzyme 1s used as a biomarker for petroleum hydrocarbon exposure, and with impending oil exploration of the Arctic, in particular the Barents Sea, the current studies were carried out to establish the nature of the response of hepatic CYPlA to dietary petroleum hydrocarbon injestion in Polar cod at their natural environmental temperatures during the breed~ng season Polar cod Boreogadus salda maintained at 0°C contain a hepatic CYPlA which displays immunochernical and nucleotide homology with other piscine CYPlAs and displays typical transcnptional induction by R-napthoflavone or crude mineral oil. The enzyme is induced in both male and female fish fed artificial diets contaminated by crude oil during the period of sexual maturation despite an overall suppression of activity in female fish and a cessation of feeding for 3 wk immediately prior to spawning. The results Indicate that use of CYPlA measurements in this species for biomonitoring oil exploration and production in the Arctic environment is a valid procedure.
8.3 SPATIAL VARIABILITY OF TURBULENCE CHARACTERISTICS OBSERVED DURING JOINT URBAN 2003

We present analyses of turbulence measurements made with sonic anemometers on five meteorological towers during Joint Urban 2003. We focus on the spatial variability of turbulence characteristics observed in the Oklahoma City metropolitan area. Intercomparisons of turbulence statistics observed at the five tower locations and between urban and suburban domains demonstrate significant heterogeneity of turbulence characteristics in the surface layer over the city. Comparisons between our results and previously documented similar analyses are also presented.
Analysis of pricing American options on the maximum (minimum) of two risk assets

We use a PDE argument to deal with the mathematical analysis of the valuation of American options on the maximum/minimum of two assets. There are several factors which affect the valuation of options, such as stock price, strike price, the time to expiry, volatilities, the correlation constant, the risk-free interest rate and dividends. The first problem we are concerned with here is what happens to the prices of options if one of these factors is increasing while the others remain fixed. In the second part of this paper, the properties of the optimal exercise boundary of option as free boundary of the parabolic obstacle problem are studied such as monotonicity, convexity and asymptotic behavior.

MARCOPOLO: CONTEXT-SENSITIVE MOBILE COMMUNICATION SUPPORT

People with Autism Spectrum Disorder and aphasia often have impairments that limit their ability to communicate verbally. Consequently, their daily activities, social interactions, and quality of life are affected. We have developed a customizable context-sensitive application, MarcoPolo, that can help these populations overcome challenges by providing vocabulary support both orally and visually. Initial evaluations of MarcoPolo have helped refine the application and have illustrated that contextsensitive mobile applications can support communication. Several additional studies will be run to further evaluate the efficacy of context-sensitive communication support. Two of these will start in 2011 and early results will be presented at FICCDAT.

The interaction between the Peltier module, a water block and the heat sink with a fan has been investigated. A thermal model of the cooling/heating system has been developed, as well as software for determining parameters of the Peltier modules and for analysis of the system operation conditions has been implemented. The obtained results of calculations were compared with the results of experimental tests.
Initio Modelling of Zirconium Hydrides

Zirconium alloys are very suitable as fuel claddings and structural components in nuclear reactors due to their low cross section for absorption of thermal neutrons and high resistance to corrosion and irradiation damage. Zirconium alloys are however susceptible to hydrogen embrittlement. Precipitation of zirconium hydrides is attributed to the embrittlement effect in zirconium alloys. In this project ab-initio simulations of αZr and the three different zirconium hydrides γ-ZrH, δ-ZrH1.5 and -ZrH2 are performed to calculate structural, elastic and thermal properties of these different compounds. The goal with the project was to calculate the equilibrium structures of the H-Zr system using ab-initio methods. The results from the calculations of thermal and mechanical properties were found to be in good agreement with previous results and experiments where these were available. Calculations of the phonon band structure for the different hydrides show that the band structure of the hydrides has two characteristic bands, one corresponding to vibrations in the zirconium sublattice and one corresponding to vibrations in the hydrogen sublattice. The calculated heat capacity of the different compounds was found to be described very well by the Einstein model for the heat capacity of a solid. By calculating the free energy of formation for the different compounds it was found that at high hydrogen concentrations -hydride is the equilibrium structure. At intermediate hydrogen levels the equilibrium structure can’t be determined.
