Study of the immune system of mosquitoes against insecticides: enzymatic activities and genetic mutation in anopheles gambiae populations at natitingou, north-east of Benin

In order to study the immune system of mosquitoes against the use of insecticides in their ecological environment, a study has been carried out on the enzymatic activities and genetic mutation in Anopheles gambiae populations in the district of Natitingou, northern Benin from January to May 2016. Bioassay tests to assess the susceptibility of malaria vectors were done where females of An. gambiae aged to 2-5 were subjected to insecticide-impregnated papers (permethrin 0.75%, delthamethrin 0.05%, DDT 4%, and bendiocarb 0.1%) following WHO testing protocol.

Selection of mathematical modelling for forecasting of rice production in Assam, India

The role of rice is vital in the development of economy of Assam as well as India. Forecasting of rice production by using time series analysis techniques may be helpful to find out the best fitted model to forecast the production of rice in Assam. Prediction of rice production in near future will help the authority to adopt appropriate strategy to tackle the management of economy related to rice production.

Crafts, design and materials engineering, a possible dialogue

The interaction between Materials Engineering, Design and Social Sciences was the key point for the development of this article. The article evidences the planning, development and insertion of a new composite in the productive chain of a small family company, from empirical techniques, in the production of sacred artifacts in plaster. The developed composite comes from the combination of a brewing residue (diatomaceous earth) and plaster.

Access control scheme to big data using privacy preserving policy

Controlling the access to a huge amount of big data becomes a very challenging issue, especially when big data are stored in the cloud. Ciphertext-policy attribute-based encryption (CP-ABE) is a encouraging encryption technique that helps end-users to encrypt their data under the access policies defined over some attributes of data consumers and only allows data consumers whose attributes satisfy the access policies to decrypt the data. In CP-ABE, the access policy is attached to the ciphertext in plaintext form, which may also leak some private information about end-users.

The environment and growth nexus: An empirical examination of the environmental kuznets curve hypothesisin cote d’ivoire

The objective of this paper is to contribute to a better understanding of the environment and growth nexus in Cote d’Ivoire and assess the EKC hypothesis for CO2.The analysis is extended to investigate the long run relationship between CO2 emissions and Agricultural Value Added, Industrial as well as Services Value Added. The data used ranged from 1960 to 2015. An ARDL model is used to assess long run relationship between CO2 emissions and per capita GDP. We found that CO2 emissions and per capita GDP are not cointegrated.

Evaluating nutrition interventions to households living with orphans aged 6-59 monthsin kakamega County, Kenya

Child malnutrition is globally the highest risk factor for illness and death. It contributes to more than half of deaths in children worldwide. Children who lose their parents may face many hardships including food insecurity and poor child care resulting into malnutrition. However, in Kenya and the entire sub-Saharan Africa the problem of orphan-hood is expected to increase in the coming years due to more deaths from HIV/AIDS and other disasters. The objective of the study was to evaluate the intervention strategies used to enhance nutritional status of orphans in Kakamega County.

Utilisation de la sismique reflexion pour l’etude tectonique de la marge d’abidjan (Cote D’Ivoire): decrochement et extension

Analysis of severalseismic profiles resulting from 2D seismicr eflection allowed to study structural basis of Abidjan margin (Côte d’Ivoire) during lower Cretaceous. The principal structural features, normal faults, tilted blocks, grabens, listricfaults and structures in "flower" and "ponytail", observed mainly in Albia sedimentary series indicate that this region of Ivorianmarg in results from geological historypolyphase in connection with both large scaled extral strike movement and distension.

Quality of coffee grown at pastos dos bois farm

In great development of the Brazilian economy is largely due to coffee, and the country is one of the main producers of the fruit. The first coffee plant was brought from the French Guianas and its cultivation started in Belém. The spread of the fruit to the whole national territory was fast. The valorization of the fruit is made through its quality that is defined with a set of chemical, physical and sensory properties.

Effect of grazing exclusion on carbon storage on grazing lands: A Review

Grazing exclusion is increasingly practiced in most grassland ecosystems of the world and is the key management aspect to restore degraded grasslands. This review is initiated to explore the contribution of grazing exclusion in increasing ecosystem carbon sequestration. This review includes research findings from almost all types of terrestrial grassland ecosystems in the world. It produces conclusion from recently conducted research findings regarding the importance of grazing exclusion on biomass and soil carbon stock.
