This expression is the focal point of this article which analyses and discusses the functional purpose for which Artificial Intelligence has been invented. This article also aims to unravel the sole aim behind the invention of a software that mimics human cognition and reasoning which are particularly human characteristics. In the face of this paradox, researchers find themselves at the threshold of a problematic caused by the success of the scientific and technological advancement which resulted in creating a “talking”:” cognitive” software that made researches rethink the concept and function of “the mind” outside its natural, existential space and its human characteristic. In this respect, other questions raise like can machines think and therefore humanised? What is the future of human existence in light of mechanised human technological advancement
Effets Des Conservateurs Acides Et Hydrocolloïdes Alimentaires Sur La Durée De Conservation Du Lait Cru à La Température Ambiante
No full textLa présente étude a été initiée afin d’étudier les effets des conservateurs acides (CA) et hydrocolloïdes alimentaires (HC) sur la durée de conservation du lait cru à la température ambiante et sur la qualité du lait. Pour ce faire, les échantillons de lait cru ont été traités avec différentes doses des conservateurs acides (l’acide citrique E330 et l’acide ascorbique E300) et hydrocolloïdes alimentaires (l’Agar-agar alimentaire E406 et Amidon E1400). Les doses desdits conservateurs acides et des hydrocolloïdes alimentaires ont été variées dans l’optique de trouver la dose optimale pouvant prolonger la durée de conservation du lait cru tout en préservant la qualité physicochimiques, microbiologiques et organoleptiques. Au terme des investigations faites, il a été observé que les conservateurs acides utilisés ont pu préserver la qualité microbiologique des échantillons du lait et n’ont pas présenté les effets significatifs sur les valeurs finales de pH. Par contre, les hydrocolloïdes alimentaires utilisés ont eu l’effet escompté en empêchant la coagulation du lait en présence des acides mais uniquement lorsque la dose appliquée était ≤ 0,3 g dans 100 mL de lait. L’acide citrique a été plus efficace que l’acide ascorbique, tandis que le meilleur hydrocolloïde alimentaire s’est avéré être l’Agar-agar alimentaire (E406). Sur la base des résultats de ces études, il est possible de conclure que les conservateurs acides et les hydrocolloïdes alimentaires peuvent être des outils efficaces pour prolonger la durée de conservation du lait cru à température ambiante et de limiter la dégradation microbienne du lait cru. Ces substances peuvent aider à améliorer la sécurité alimentaire et la nutrition dans les régions où la conservation du lait cru pose des sérieux problèmes
Air Layering Of Three Agroforestry Species In The Guinean Savannah Highlands Of Adamawa In Cameroon.
No full textXimenia americana, Vitex doniana and Lophira lanceolata are species prized by the populations of the Guinean savannah highlands of Cameroon. They are unfortunately still in the wild where they are subjected to various pressures. From the perspective of the conservation and enhancement of local biodiversity, their domestication appears necessary. The objective of the work is to study the vegetative propagation by air layering of these fruit trees. The experimental device used is a split-split-plot with three repetitions. Species represents the main treatment; the substrates constitute the secondary treatment while the covering of the layers with aluminum foil represents the tertiary treatment. The experimental unit was 30 layers. The rooting rate of layers varies significantly (0.000 < 0.001) from 48.88±1.89% in Ximenia americana to 81.38±2.08% in Lophira lanceolata. Sphagnum was the best substrate with 69.63±1.38% against 61.66±1.54% for the black soil-sawdust mixture. The analysis of variance reveals a significant difference for the substrates (0.0025 < 0.01). Covering the layers with aluminum foil presented a rate of 69.44±2.15% while the uncovered layers presented 61.85±1.54%, the analysis of variance shows a significant difference (0,0031 < 0.01). Lophira lanceolata exhibited the best air layering ability; the rooted layers were weaned and acclimatized for two months before being transferred to the field. During this process 19% and 52% respectively of the layers of Vitex doniana and Ximenia americana flowered. This inexpensive technique is an essential step in the process of their domestication
Comportement Mécanique Du Schiste Traité Par Des Ajouts Du Ciment Et De La Chaux
No full textL’utilisation des ajouts pour stabiliser les sols parmis les méthodes les plus utilisées. La chaux et le ciment étaient couramment utilisés comme stabilisants pour modifier les propriétés des sols. Cette étude a pour objet de déterminer l’évolution des propriétés géotechniques d’un sol schisteux du pole universitaire ElAouana - wilaya de Jijel. Par la suite, l’échantillon de sol a été modifié avec des proportions d’additifs qui comprennent 0, 1 %, 3 % et 7 % du remplacement du ciment et de la chaux en poids sec, afin de tester les différents proprietées de la patte fraiche du sol argileux. Enfin, on conclut que l’addition d’un liant (ciment ou chaux) au sol schisteux provoque une réduction de la plasticité, une amélioration des caractéristiques de compactage au Proctor, une augmentation rapide de l’indice de portance immédiat en fonction du traitement et une augmentation de la cohésion et de l’angle de frottement
Cloning, Expression, And Structural Modeling Of Two Alkaline Serine Protease Genes From Extremophilic Bacillaceae -related Species: Application In Valorization Of Invasive Crustaceans
No full textTwo novel protease genes sapA and sapN from the thermophilic Anoxybacillus kamchatkensis M1V and Melghiribacillus thermohalophilus Nari2AT strains respectively, encoding a polypeptide of 381 and 379 residues, were identified, cloned and successfully heterologously expressed in Escherichia coli BL21(DE3)pLysS. The deduced putative amino-acid residues of SAPA and SAPN enzymes evinced identity with proteases from Bacillus strains. The highest sequence identity value (95%) of SAPA was obtained with peptidase S8 from Bacillus subtilis WT 168, but with 16 amino-acids of difference. While, the highest sequence identity (97.10%) of SAPN was observed with Bacillus licheniformis MP1 protease, but with 10 difference residues. rSAPA and rSAPN enzymes were purified until homogeneity, characterized, and compared to wild-type proteases. The purified recombinant enzymes rSAPA and rSAPN were two monomers of about 28 and 30 kDa, correspondingly. rSAPA displayed the highest activity at pH 11 and 70°C. While, rSAPN displayed the highest activity at pH 10 and 75°C. To initiate structure-function relationships, a 3D-model of the Pro-SAPA and Pro-SAPN proteins were thereafter built based on the available structures of common proteases. The comparative molecular modeling studies with the less thermostable protease, revealed extra charged residues at the surface of SAPA and SAPN potentially participating in the formation of intermolecular hydrogen bonds with solvent molecules or generating salt bridges, therefore contributing to the higher thermal stability
