Abstract:
This article is an attempt to understand and analyze the difficulties encountered by agricultural cooperatives in the marketing of cola nuts. Despite the considerable capital generated by this sector, many difficulties are hampering the agricultural sector, which results in a sharp decline in the profits of cooperatives and producers. For the members, this is due to the lack or little commitment of the Ivorian State to revitalize this promising sector as is the case with the coffee-cocoa pair. In fact, the fact that foreign traders have direct access to growers in their production areas without going through a central structure, in particular the wholesale marketBouake, weakens domestic traders. Similarly, this situation prevents the Ivorian export circuit of Cola from having a substantial tonnage and allowing the entry of foreign currency into the country. All this contributes to devalue the label of the cola nut produced in Cote d'Ivoire.

Abstract:
La maladie du balai de sorcière du colatier est la maladie la plus importante du colatier car elle engendre d’énormes pertes de production. L’objectif principal de cette étude était d’identifier des clones de colatiers d’origine ivoirienne qui affichent le meilleur profil de tolérance à la maladie du balai de sorcière et ayant des paramètres de rendement intéressants. Pour atteindre cet objectif, un dispositif expérimental en bloc complètement randomisé à 3 répétitions a été utilisé et le facteur étudié est le clone avec 13 modalités. Les résultats obtenus montrent que 5 clones (clones 305, 314, 318, A2 et A3) n’ont pas subi d’attaque de la maladie. Les clones 311, 313, 315, 321 et 322 ont été moyennement attaqués. Sur la base des paramètres de rendement tels que le poids des noix par follicule et le nombre de noix par follicule, les clones 313 et 323 ont produit les plus grosses noix dont le poids moyen varie entre 31,98±11,60 g et 34,97±8,54 g et le clone 316 a donné un plus grand nombre de noix par follicule (en moyenne, 10,63±1,55 noix par follicules). Une classification combinant le niveau de tolérance des clones et les paramètres de rendement étudiés ont permis d’identifier les clones 313, 322 et 323 comme étant les meilleurs.Mots clés : Maladie du balai de sorcière, colatier, pertes de production, rendement.

Abstract:
Malgré son importance socioéconomique, la production ivoirienne de noix de cola est confrontée à plusieurs difficultés. Le manque de techniques culturales éprouvées constitue une des contraintes pour la domestication et la culture du colatier. Il est donc nécessaire de mettre au point des techniques adaptées à l’espèce cultivée. L’objectif de cette étude est d’optimiser la méthode de bouturage sous tunnel du colatier (Cola nitida), face aux inconvénients de la multiplication générative. Le dispositif expérimental utilisé est un Split-Splot avec deux facteurs : le génotype avec cinq modalités (5 génotypes) et le nombre de feuilles avec cinq (05) modalités (1, 2, 3, 4 et 5 feuilles diminuées de moitié). Nous avons le génotype en grande parcelle et le nombre de feuilles en petite parcelle. L’aptitude des génotypes au bouturage a été évaluée à six mois à travers le taux de survie et la mesure des paramètres de croissance et de développement. Le génotype L18A1D9 a montré la meilleure aptitude au bouturage avec un taux de survie de 41,7%. Les boutures avec 4 feuilles diminuées de moitié ont eu le meilleur taux de survie (41,7%), un bon enracinement des boutures vivantes (88,9%), une biomasse totale fraîche (4,2 g) et totale sèche (1,7 g) élevée. Le succès du bouturage sous tunnel du colatier est tributaire du génotype et du nombre de feuilles. Le nombre de feuilles recommandé par bouture est de quatre (4) pour le bouturage du colatier sous tunnel.Mot clés : Bouturage, nombre de feuilles, Cola nitida, génotype. Englsih Title: Influence of genotype and number of leaves on the growth in nurseries of cola cuttings (Cola nitida [Wind.] Schott and Endlicher.)Despite its socio-economic importance, kola nut production faces several challenges. Domestication and cultivation of kola requires the adoption of propagation techniques adapted to the crop species. The objective of this study is to optimize kola (Cola nitida) vegetative propagation by cutting under tunnel. The experimental design used was a split-splot with two factors: genotype with five modalities (5 genotypes,) and leave number with five (05) modalities (1, 2, 3, 4 and 5 leaves cut in half). The ability of genotype to cutting propagation was assessed by measuring growth parameters. The survival rate of the cuttings was evaluated at six months. Root growth, number of new leaves, height gain and biomass were subsequently measured. Genotype L18A1D9 has the best ability for vegetative propagation by cuttings with a survival rate of 41.7%. To optimize vegetative propagation by cuttings under tunnel, 4 leaves cut in half by cuttings must be used for acceptable success rate (41.7%), good rooting (88.9%), a high total fresh biomass (4.2 g) and total biomass (1.7g). The success of kola vegetative propagation depends of genotype and the leave number per cutting. The number of leaves per cuttings recommended per cuttings is four (4) for kola vegetative propagation.Keywords: Cuttings, number of leaves, Cola nitida, genotype.

Résumé Soigner l'affect en remodelant le corps en milieu yaka Les cultes therapeutiques chez les Yaka à Kinshasa et dans le sud-ouest du Zaïre réélaborent l'identité du patient et son expérience du corps en marge de la communauté. Je traiterai de la therapie mhwoolu pour handicapés physiques et déséquilibres humoraux ainsi que pour certaines formes de folie focalisées autour de cauchemars où apparaissent la rivière, les ravins, les rapides, les tourbillons, la foudre. Au début de l'initiation, le patient reçoit une série de figurines anthropomorphes en guise d'objet transitionnel. Celles-ci expriment une transition graduelle du silure au corps humain adulte, sexué et, finalement, investi des attributs majeurs de l'adulte. Ces figurines cultuelles mettent en scène la famille : les parents, enfants et serviteurs y compris. Elles offrent un espace potentiel où puissent s'ancrer de multiples identifications, façonnées culturellement. Le patient vit une sorte de contact physique avec ces objets cultuels ou sculptures disposés sur un autel parallèlement à son lit dans la maison de cure. Il les masse, tout comme son propre corps, les vitalise de sa propre force (au moyen de noix de cola mâchées). Après s'être adressé aux sculptures dans une mélopée rythmique quasiment sans paroles, il passe après quelques jours au chant ésotérique, pour finalement parler en son propre nom et nommer les différentes figurines du titre de chef, parent, frère ou sœur, cadet, etc. Les objets cultuels ont donc une fonction essentiellement médiatrice entre l'affectif et le corps, la symbolisation et le langage, parent et enfant, masculin et féminin, esprits et vivants, moi et les autres.

Abstract:
NOX emissions during the combustion of coal would cause serious pollution to the atmosphere. It is particularly important to reduce NOX pollution during the combustion process by replacing loose coal with clean coke. The use of clean coke for civil is one of the main ways to reduce NOX emissions, which is mainly formed by the mixed dry distillation of metal additives and coal. The coke samples with different proportions of metal additives were prepared by physical mixing method, and the NOX emission law of clean coke at different temperatures was studied in a high-temperature tube furnace reactor. The results show that the addition of Fe alone has a significant effect on the control of NOX emissions, and the co-doping with Ce can further promote the reduction of NOX, so as to achieve the final low emission of NOX. While the reaction temperature is 1000 ℃ and the addition ratio is 2:1, the NOX reduction rate is 73%. It has important practical value and scientific significance for the clean utilization of coal and the treatment of NOX in the atmosphere.

Abstract:
With the increasingly serious impacts of NOx on environment, measures of controlling NOx are extremely necessary. Reburning technology has become a proven and effective method to control the emissions of NOx. In this paper, CFD software has been used to simulate the reburning process of South American coal (SAm) so as to study the effect of the reburning on the combustion in the furnace and NOx reduction. The result shows that, SAm reburning can reduce NOx emissions effectively, and removal rate of NOx reaches 50.63% with respect to the conventional combustion.

Abstract:
This paper presents the findings of research into cofiring two Bosnian cola types, brown coal and lignite, with woody biomass, in this case spruce sawdust. The aim of the research was to find the optimal blend of coal and sawdust that may be substituted for 100% coal in large coal-fired power stations in Bosnia and Herzegovina. Two groups of experimental tests were performed in this study: laboratory testing of co-firing and trial runs on a large-scale plant based on the laboratory research results. A laboratory experiment was carried out in an electrically heated and entrained pulverized-fuel flow furnace. Coal-sawdust blends of 93:7% by weight and 80:20% by weight were tested. Co-firing trials were conducted over a range of the following process variables: process temperature, excess air ratio and air distribution. Neither of the two coal-sawdust blends used produced any significant ash-related problems provided the blend volume was 7% by weight sawdust and the process temperature did not exceed 1250?C. It was observed that in addition to the nitrogen content in the co-fired blend, the volatile content and particle size distribution of the mixture also influenced the level of NOx emissions. The brown coal-sawdust blend generated a further reduction of SO2 due to the higher sulphur capture rate than for coal alone. Based on and following the laboratory research findings, a trial run was carried out in a large-scale utility - the Kakanj power station, Unit 5 (110 MWe), using two mixtures; one in which 5%/wt and one in which 7%/wt of brown coal was replaced with sawdust. Compared to a reference firing process with 100% coal, these co-firing trials produced a more intensive redistribution of the alkaline components in the slag in the melting chamber, with a consequential beneficial effect on the deposition of ash on the superheater surfaces of the boiler. The outcome of the tests confirms the feasibility of using 7%wt of sawdust in combination with coal without risk to the efficiency of the unit, its combustion process and with the benefits of emissions reductions. Furthermore, they show that no modification to the existing coal transport system and boiler equipment is necessary to achieve this outcome.

Abstract:
In order to achieve ultra-low NOx emissions, the effects of total excess air coefficient, air coefficient in main combustion zone, blended-coal combustion and ammonia nitrogen molar ratio on a 330 MW coal-fired boiler combustion were studied by numerical simulation. The results show that the velocity field and temperature field in the furnace have synergy, the better the synergy is, the faster the temperature rises, and the more NOx it generates. Compared before and after urea spraying, the NOx concentration decreased with the decrease of the total excess air coefficient, the optimum total excess air coefficient is about 1.15, and the denitrification rate is as high as 76.2%. The smaller the air coefficient in the main combustion zone is, the smaller the NOx concentration is. The optimum air coefficient in the main combustion zone is about 0.92, and the denitrification rate is 85%. After urea injection, the denitrification rate of high volatile coal combustion is higher than that of low volatile coal combustion, and the reasonable blending mode of coal can reduce NOx emissions. The larger the ammonia-nitrogen molar ratio is, the lower the NOx concentration is. When the ammonia-nitrogen molar ratio is greater than 2, the amount of ammonia escape at the flue outlet exceeds the standard. When the ammonia-nitrogen molar ratio is less than 1, the NOx concentration at the flue outlet is greater than that before urea injection. The optimal ammonia-nitrogen molar ratio is about 2.

Abstract:
The influence of pulverized coal particle size on combustion and NOx formation of 660MW tangential combustion ultra-supercritical boiler in a power plant was studied by using commercial software FLUENT. The average particle size of pulverized coal was set at 61μm, 71μm and 80μm, respectively. The results show that with the decrease of pulverized coal particle size, the overall temperature level of the boiler increases, the average temperature of the main combustion zone increases, the temperature of the upper part of the main combustion zone decreases, and the combustion of pulverized coal is more incomplete. However, the probability of particles sticking to the wall and the probability of coking and slagging of the boiler increases. The amount of NOx produced in the main combustion zone decreases, while the amount of NOx produced in the upper part of the main combustion zone increases, while the overall amount of NOx produced increases slightly.

Abstract:
De nombreuses études ont mis en évidence le potentiel biologique des tocotriénols (T3), appartenant à la famille de la vitamine E, notamment dans le domaine des maladies cardiovasculaires et de l'inflammation chronique. Une étude phytochimique, précédemment menée au SONAS, a permis d'identifier dans l’extrait dichlorométhanique des écorces de Garcinia amplexicaulis, différents T3 ω-oxydés tels que le δ-amplexichromanol (δ-AC) et l'acide δ-garcinoïque (δ-AG). Un criblage virtuel de ces dérivés sur différentes cibles impliquées dans les processus inflammatoires a révélé leur potentiel inhibiteur de la 5-LOX. Ces données in silico ont été confirmées in vitro sur 5-LOX purifiée et sur leucocytes polymorphonucléaires. Les travaux rapportés ont pour but de mieux appréhender le mode d'action original de ces métabolites tout en optimisant l’activité des premiers hits. Une telle approche requiert de grandes quantités de dérivés tocotriénoliques. Cependant, les principales sources naturelles de T3 fournissent un mélange complexe de métabolites impliquant des processus de purification particulièrement délicats. Ainsi, au cours de ce travail, des hémisynthèses efficaces de dérivés T3 à fort potentiel biologique ont été développées à partir du δ-AG, principal dérivé T3 isolé des noix de Garcinia kola, source végétale renouvelable et facilement accessible. D’autre part, les travaux de pharmacomodulation réalisés reposent sur des études préliminaires de modélisation moléculaire, complétées par le développement de diverses stratégies de synthèse pour accéder à des analogues originaux de la vitamine E, inhibiteurs potentiels de la 5-LOX<br>Many studies highlighted the biological potential of tocotrienols (T3), a vitamin E subfamily, especially in the field of cardiovascular diseases and chronic inflammation. A phytochemical study, previously conducted at SONAS, led to the isolation and characterization of δ-amplexichromanol (δ-AC) as the main and original secondary metabolite from Garcinia amplexicaulis barks (dichloromethane extract) along with other oxidized T3 analogs such as δ-garcinoic acid (δ-GA). A pharmacophore based virtual screening of these derivatives against various anti-inflammatory targets showed that this class of T3 analogs could be considered as potential 5-LOX inhibitors. It was confirmed by in vitro assays when δ-AC and δ-GA were evaluated as inhibitors of purified 5-LOX, or in polymorphonuclear leukocytes. We then decided to carry on our study to further understand the original mode of action of these metabolites while optimizing the anti-inflammatory properties of the first hits. Such approach requires large amounts of tocotrienolic derivatives. However, usual natural sources of T3 provide complex mixtures involving particularly challenging purification processes. Thus, this work aim at designing efficient semisynthesis towards pharmacologically relevant T3 derivatives were developed from -GA, the main T3 derivative isolated from Garcinia kola nuts, a renewable and easily available vegetal source. Moreover, pharmacomodulation of the tocotrienolic backbone relied on preliminary docking studies and then required the development of various synthetic strategies to access original vitamin E analogs as potential 5-LOX inhibitors

Abstract:
In this paper, I trace the theme of revenge across Drive (Refn, 2011) and John Wick (Leitch and Stahelski, 2014). Professor von Hallberg helped me understand these films as vehicles for understanding certain ideas. Throughout the semester I consulted the work of several literary critics to arrive at a better sense of what neo-noir is and to better understand the world of these films. Through close analysis of specific scenes, I hoped to determine what I would learn about vengeance if I lived in the world that these characters inhabit. After watching and re-watching both films several times, I went through scene by scene and observed the details that stood out to me the most. I related these to the literature I had read and suggested what each detail might mean before drawing any conclusions. Once I had completed the core analysis, I reviewed these observations and synthesized them into general claims. I affirmed that revenge was closely related to von Hallberg’s notion of “trust” as a “horizon of hope” (von Hallberg 2). In the end, it was apparent that in punishing those responsible, the protagonists of these films committed to destroying any and all “obstacles to the [re]construction of trust” (von Hallberg 5). Both protagonists are portrayed as avengers who are driven toward the destruction of “the fakery and greed of those around them” (von Hallberg 36). In these films, to extract revenge is to punish the “corrupt[t] [and] [re]buil[d] [in] a world governed by self-interest” (von Hallberg 36).

Abstract:
Experiments were conducted on a 200 kW downward-fired, pilot-scale furnace where residence times and temperatures are comparable to practical units. Nine bituminous coals were used as reburning fuels to investigate various aspects of the reburning process, including key process parameters (operating stoichiometries, reburn fuel fraction, primary zone NO concentration, reburn zone residence time, temperature and mixing effects) and to assess the effectiveness of pulverised coal, including microfine, as reburn fuel. The results obtained showed that the extent of NO reduction was dependent on optimising the different process variables, and the maximum reduction achieved by doing so was 75%. The most influential variables were those coupled to the reburn zone, with the reburn zone stoichiometry being the dominant impact variable. For the range of reburn zone stoichiometries studied (0.85 - 1.03) no optimum value was obtained, however, higher reductions were generally achieved under fuel rich operations. The direct effect of varying primary zone stoichiometry on reburn performance was of minor significance, however, secondary effects such as variation in the reburn zone stoichiometry can be significant. The NO reduction process was mostly completed in the reburn zone where the optimum reburn zone residence time was around 450 ms, and only marginal gains were achieved beyond this point. The NO reduction efficiency increased with increasing primary NO concentration up to around 600 - 700 ppmv, after which the trend levels off, however, at low primary NO (<200 ppmv) it was difficult to obtain a positive NO reduction efficiency. The amount of reburn fuel or Rff required to generate the hydrocarbon radicals necessary for effective NO control was not conclusively quantified, however, from the results obtained the optimum amount of reburn fuel was in the region of 20-25% of the primary fuel input. Lower inlet gas temperature in the reburn zone generally enhanced NO reduction, however, this effect diminished under sufficiently fuel rich conditions. Furthermore, the effect of temperature in the reburn zone was dependent on residence time, with high temperature (1773 K) and long residence time (>500 ms) achieving higher reduction. Improved mixing conditions in the reburn zone enhanced reburning effectiveness, however, in fuel lean operations poorer mixing was found to improve NO reduction through local fuel rich pockets. Finer particle size distribution of the reburning coal gave rise to better NO reduction and higher burnout efficiency. The carbon burnout efficiency was around 85% - 95%, and higher gas temperature improved carbon burnout efficiency, however, under fuel rich conditions (SR2=0.85) burnout efficiency was hampered by the low oxygen concentration. Finally, the results of the multi-variate analysis undertaken to determine the importance of some of the above operational parameters on NO reduction as well as the influence of reburn coal properties such as fuel nitrogen content and volatile matter, confirmed the importance of SR2 as the dominant variable in coal reburning. The proximate volatile matter content was the most influential characteristic of the reburn fuel affecting reburn performance, while fuel nitrogen content was not as influential a parameter for the range of operating conditions and coals studied.

Abstract:
Coal bound moisture is a key issue in pulverized coal fired power generation. Coal being hygroscopic, accumulates considerable surface moisture with seasonal variations. A few varieties of coals are having unusually high inherent as well as surface moisture that affects the pulverizer performance and results lower thermal efficiency of the plant. A proper coal drying is essential for effective pulverization and pneumatic conveyance of coal to furnace. But, the drying capacity is limited by available hot airflow and temperature of hot primary air. Even, use of high-grade coal for blending would not provide the entire useful heat value due to moisture, when used for matching power plant design coal parameters. Besides, the inefficient mining, transportation, stacking and associated coal fleet management deteriorates the “as fired” coal quality affecting cost while purchased on “total moisture and gross heat value” basis. Partial devolatilisation of coal in a controlled heating process, prior combustion in fuel-rich environment ensures better in-furnace flame stability and less residual carbon in product of combustion. It improves the opportunity of a lower flame zone temperature, delivering better control over thermal NOx formation from fuel bound nitrogen. The pulverized coal fired power plants use coal feeders in either gravimetric or volumetric mode of feeding that needs correction for moisture in coal which changes the coal throughput requirement. In this paper an integrated coal drying and partial coal gasification system model is discussed to improve the useful heat value for pulverized coal combustion of high moisture typical power coals so that related improvement in coal throughput can be carried out by application of suitable coal drying mechanism like Partial Flue Gas Recirculation through Pulverizer (PFGR©) for mitigating the coal throughput demand with optimizing available pulverizing capacity along NOx control opportunity without derating steam generation capacity of the boiler.

Abstract:
From the view point of future coal utilization technology for the thermal power generation systems, the coal gasification combined cycle system has drawn special interest recently. In the coal gasification combined cycle power generation system, it is necessary to develop a high temperature gas turbine combustor using a low–BTU gas (LBG) which has high thermal efficiency and low emissions. In Japan a development program on the coal gasification combined cycle power generation system has started in 1985 by the national government and Japanese electric companies. In this program, is planned to develop the 1300 °C class gas turbines. However, in the case of using a hot type fuel gas cleaning system, the coal gas fuel to be supplied to gas turbines will contain ammonia. Ammonia will be converted to nitric oxides in the combustion process in gas turbines. Therefore, low fuel–NOx combustion technology is one of the most important research subjects. This paper describes low fuel–NOx combustion technology for 1300 °C class gas turbine combustor using low BTU coal gas fuel. Authors have showed that the rich–lean combustion method is effective to decrease fuel–NOx (1). In general in rich–lean combustion method, the fuel–NOx decreases, as the primary zone becomes richer. But flameholding becomes very difficult in even rich primary zone. For this reason this combustor was designed to have a flameholder with pilot flame. Combustion tests were conducted by using a full scale combustor used in 150 MW gas turbine at the atmospheric pressure condition.

Abstract:
Over the past decade, members of the Upgraded Coal Interest Group and EPRI, the Department of Energy, the Energy and Environmental Research Corporation (GE-EER), Washington Energy Processing (WEP), Penn State University and the previous owners and operators of Seward Station located in western Pennsylvania, conducted a series of formulation and combustion tests using coal waste fines as a low solids coal water slurry cofiring fuel for electric power generation. The fine coal was recovered from coal fines impoundments and fresh coal cleaning plant fines that were cleaned, thickened and then cofired with pulverized coal in utility scale boilers. This paper explains the need for a program to eliminate these impoundments and describes the results of some of the tests conducted on the technology that demonstrate the effectiveness of trimming NOx emissions by the use of slurry cofiring. This method of trimming NOx emission has been shown to have the capability of reducing NOx emissions by 20% to 35% below the levels achieved by some low NOx burners and selective non-catalytic reduction systems (SNCRs).

Abstract:
Four typical coals with different ranks around China were used as reburning fuels to evaluate its ability for NOx reduction in a pilot scale entrainment reactor. The selected four coals have similar fuel-N containing from 1.09% to 1.30% at different coal rank from bituminous to anthracite. Results show that Bituminous coal (Yanzhou, Huainan) are advantages than anthracite (Jincheng) and lean coal (Zhengzhou). Due to Yanzhou coal’s more moisture and less ash contents, it’s the best coal for reburning in this test. When using Huainan coal as reburning fuel, carbon in ash increased form 3.64% to 4.52% along with the increase of heat input from 15 to 25%. The optimal temperature for Huainan coal reburning is around 1300°C no larger than 1400°C. With the increasing of reburn zone stoichiometric ratio from 0.6 into 1.2 the NO reduction efficiency decreased from 52.1% into 17.6%. The impact of particle fineness on the NO reduction is not so evident.

Abstract:
The Cool Water Coal Gasification Project requires a gas turbine combustion system to burn a high hydrogen medium-Btu coal gas produced in an oxygen-blown gasifier. The gas turbine selected for this demonstration plant is a General Electric Company MS7001E unit. The plant is located in Daggett, California, a location requiring compliance with stringent environmental regulations; that is, oxides of nitrogen (NOx) at 63.5 kg/hr and carbon monoxide (CO) at 35.0 kg/hr in the machine exhaust. The plant operating configuration requires fuel gas to be supplied at 330 °K and 477 °K with 20%/vol moisture blended. A combustion system was developed enabling the gas turbine to operate from full speed no load to full load on both fuel gas configurations. Distillate oil capability was also incorporated to facilitate safe machine startup and shutdown. Emissions requirements for NOx were met with steam injection, “CO” by combustor design, and sulfur oxides are met by fuel gas cleanup. A conventional combustion liner sleeve with a standard air admission schedule was used. A unique fuel nozzle, based upon past low-Btu fuel work, was designed incorporating the latest low erosion oil nozzle. One combustor of the 10 fitted to an MS7001E was tested at full pressure and airflow. Test results indicate, as predicted analytically, that NOx prediction varies substantially between cold dry fuel gas and hot wet gas. NOx compliance was attainable with little degradation of other design considerations. Carbon monoxide emissions were well below the required limits.
