Évaluation De La Protection Des Bananiers (Musa Spp.) Élicités Par Le Méthyle Jasmonate Contre La Maladie Des Raies Noires Causée Par Mycosphaerella Fijiensis Morelet En Côte D’ivoire

Ncho Xavier Edouard, Konan Yao Kouakou François, Mohamadou Doumbia Lamine, Traore Siaka, Kouakou Tanoh Hilaire
L’effet du MeJA sur la sévérité de Mycosphaerella fijiensis, champignon responsable de la maladie des raies noires (MRN) chez deux cultivars de bananier (Grande naine, sensible et Fhia 21, tolérant) a été étudié. Ainsi, des plants de bananier élicités sont inoculés par une souche pathogène de M. fijiensis puis le degré de protection des bananier contre la MRN est évaluée sur feuilles détachées par la détermination du taux de croissance du mycélium, du niveau de contamination et de la teneur en pigments foliaires. Les résultats montrent que le MeJA représente une alternative intéressante à l’utilisation des pesticides. En effet, sous son action, le cultivar Grande Naine a acquit une capacité de tolérance à M. fijiensis qui est comparable à celle du cultivar Fhia 21. Le MeJA a provoqué une accumulation de pigments chlorophylliens (chlorophylle a et chlorophylle totale) et de caroténoïdes chez le cultivar Grande Naine dont les teneurs sont proches de celles du cultivar tolérant Fhia 21. De plus, l'application du MeJA a amélioré l'équipement de pigment fonctionnel et de l'état de verdure des feuilles des bananiers. Ainsi, le MeJA améliore l'état physiologique des bananiers en induisant une protection contre la MRN en contexte non infectieux. La pulvérisation foliaire du MeJA est une stratégie efficace de lutte biologique contre M. fijiensis et peut être associé dans un système de lutte intégré contre la MRN en bananeraie.

Quantification of Soil Erosion using Remote Sensing and GIS between Cuddalore and Pondicherry Region, Tamilnadu, India

Edwin D Thangam and RM. Narayanan
Soil erosion is one of the most serious environmental problems in the world today. The human interventions with natural environment cause severe damage to the productive land and economy hence the management of soil, water and vegetation resources on micro level watershed basis is important. In this study the soil erosion intensity of each micro watershed was derived based on soil texture (silty clay, loamy sand, sandy loam, coarse sandy loam, sandy clay loam, clay loam and clay), rainfall, permeability, slope length and land cover factors. To minimize the decline of soil productivity and water quality, soil loss rate are essential to optimize the use of resources for soil conservation. The mean annual soil loss is estimated using remote sensing and GIS techniques for 358 micro watersheds based on modified USLE equation. The mean annual soil loss for the study region amounted to a range from 0.003 ton/ha/year in low lying plains (flat topography) to 4.06 ton/ha/year in areas of higher elevation. Further the soil erosion was classified into four different categories from maximum to very low intensity of erosion. The study results with 21 micro-watersheds indicated with (100-500 tons/year) severe erosion and are prioritized for soil conservation measures.

Enhancing Security of data in Cloud Environment using Data Protection as a Service (DPaaS)

Vijyendra Karpatne and E.J.Thomson Fredrik
Despite the popularity of Cloud computing, it has many challenges. Teething problems are highlighted in major cloud development applications in providing cloud services. Security of the clients’ data should be a joint venture of organizations, institutions, companies, agencies, and governments to eliminate the cyber security threat which results in cyber terrorism activities. Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) are the services provided by Cloud computing. But all these services create various problems in the cloud data such as Data breaching, authentication problems, data loss, abusing of cloud services. During data transmission, the major challenge is data integrity. Having all the security measures in cloud organization will prove that the valuable data which are transmitting, are not misrepresented. In order to overcome the cloud security issues, we propose Data Protection as a Service (DPaaS) to enhance cloud data security. The implementation results of DPaaS shows that it eliminates cloud security issues and cloud data integrity issues. DPaaS is the only cloud platform which handles the integrations as a fully managed service. The protection on data getting transmitted will absolutely be strong as there will be no loss of data and there will not be threat for shoplifting the data.

Contribution A La Réévaluation Des Ressources En Eau De Surface Du Bénin Par Une Analyse Des Séries Hydrométriques Récentes

Zevounou Crépin, Zannou Arnaud and Dahodo Médard
Cette étude porte sur la recherche de tendance dans les séries hydrométriques et la réévaluation des ressources en eaux de surface du Bénin pour servir à des fins d’ingénierie dans la mise en place des ouvrages d’assainissement, de franchissement, d’art et d’implantation de barrages. Les résultats issus du test d’analyse de tendance ont permis d’observer des tendances à la baisse sur la station de Porga au Nord-Ouest suivant les périodes de l’étude. La station de Coubéri au Nord affiche des tendances à la hausse suivant la récente période. Au Sud, nous avons obtenu des tendances positives dans toutes les séries. L’estimation desdites ressources a permis de montrer que par rapport à la période allant de 1952 à 1984, les écoulements ont augmenté de l’ordre de 8% sur la période récente allant de 1985 à 2009. Aussi les ressources en eau de surface du Bénin s’évaluent actuellement à 13,88 milliards de mètre cube par an contre 13,106 milliards de mètre cube par an sur la période 1952-1984. Au nord, il y a une baisse et au Sud une hausse. Ces modifications de la disponibilité globale des ressources en eau peuvent être la conséquence de la dynamique des états de surface d’une part, et d’autre part, la traduction des changements et variabilités climatiques.

Babatunde Afolabi
The study examined Industrial Output and Economic Growth of Nigeria in the 21st century. The model specified economic growth measured by real gross domestic product (rGDP) which is already adjusted for inflation as dependent variable while Industrial Output was proxied using Manufacturing Value Added, Agriculture Value Added, Electricity Production and Government Capital Expenditure on Education domestic credits. Annual time series data from 1981 to 2014 was sourced from World development indicator. The empirical analysis was carried out using the Autoregressive Distributed Lag Co-integration Technique. The Research aimed at providing a dependable solution to the existing wide disparities between the developed and developing economies which makes Industrial Output a tool for stultifying the industrial process, and by extension, retarding the growth and development of developing economies. The study adopted the Romer Endogenous Growth Model which addresses technological spill overs (in which one firm or industry's productivity gains lead to productivity gains in other firms or industries).The study found that the long run coefficient of agricultural value added (AVA) is significant. This is as result of an increase in agricultural output will lead to an increase in its value added to the economy.

Extracting Frequent Patterns by Combining PSO and K-Means with Downward based Ranking

D.Gandhimathi1 and N.Anbazhagan
Web mining is an active and wide area that integrates quite a lot of usages for the web site design, providing personalization server and other business making decisions etc. Efficient web log mining results and online navigational pattern prediction is a tough process due to vast development in the web. More and lots of existing techniques have been used to discover the frequent page patterns with some research gap and drawbacks. In the proposed work, we propose two newly developed algorithms are utilized to conclude the frequent page pattern mining work. In this paper, initially, the web log data are pre-processed for removing unwanted records and other irrelevant details. After that, the data are clustered using hybrid approach of Particle Swarm Optimization method with K-means clustering. Then, we use the threshold value to get out the frequent page results as list. It has some unique steps to discover the list of frequent page patterns. Finally, we produce the frequent set of web pages in a downward order using new ranking based steps. In this step four digit RNV values with three different case ranges are used to produce the accurate results. It is entirely different from the other ranking methods in data mining and results are proved using Microsoft dataset.
