Cognitive Power of Language and Supposed Inference on the Handling of Plurilingual Ads By the Target Audience
NNOMO Henriette Stéphanie
Advertisers are increasingly using the mix of languages codes in the advertising registry. Thus, mother tongues, slangs and official languages intertwine to carry the advertising message to the tar-get audience. In fact, this study tackles the problem of the structures of language associations in ad-vertisements, it aims to understand their effects in memory responses to advertising. In the end, we have highlighted that the embedded language helps to promote the recall of the elements of the an-nouncement when it is known. The problem here, however, is that the influence of the perceived association of language embedded-context of use produced on the recall of the elements of the an-nouncement in the receiver, however has not been confirmed.
Keywords: linguistic mixing, embedded language, mother tongue, memorization.

The variety of proteins, present as highly conserved molecular patterns within the human white blood cells, are essential for adhesion between leukocytes and endothelium surface at the inflammatory site and migration through the interstitial tissue. A proteomics profiling of circulating leukocytes already led to the discovery of biomarkers for some very serious diseases, including the Alzheimer´s disease and better understanding of signalling pathways within the mast cells. However, many questions regarding function of leukocyte proteins are remaining open. One of the major problems in proteomic analysis is limited amounts of protein samples. In our study we presented an alternative, novel approach for isolation of sufficient amount of cellular proteins that could be applied in challenging proteomic analysis of human blood leukocytes. Our study included whole blood samples of donors of both genders, a different age categories and of different blood groups. Besides gender, an older age of test subjects and the longer storage of blood samples negatively influenced the total amount of isolated proteins.

Optimum Concentration of Sodium Hydroxide on The Strength Properties of Low Calcium Flyash Based GPC
E.Manimaran and G.Mohankumar
Development of concrete without conventional cement is the need of the hour for a healthy future. The increasing demnd for cement in concrete industries leads to atmospheric pollution by means of CO2 emission due to more cement production which must be prevented from increasing. As believed that replacement of cement with suitable alternatives can solve the problem, the development of GPC has been positively thought of using the flyash among all the pozolonic materials as the source material. But most of the works made on low calcium flyash based GPC are primarily by steam or hot oven curing and only a very few studies on ambient or exposed curing. The development of GPC using low calcium flyash with sodium based activating solution having molar concentration of 8M - 14M and liquid ratio of 2.5 is made. The influence of Molaity on the strength characteristics is studied for three different grades of GPC equivalent to conventional M20, M30 and M40 grades of cement concrete. Both hot curing and ambient curing are considered. It is observed that the expected strength of GPC is reached for specimic molarities of NaOH like 8M for GM20, 10M for GM30 and 12M for GM40 grades respectively.

Chromatographic isolation of superoxide dismutase enzyme from Calendula officinalis and its anticancer activity in vitro
Nadira Ibrisimovic-Mehmedinovic, Mirza Ibrisimovic and Jasmina Dedic
Varieties of studies have been performed worldwide to isolate the active novel compounds of plant or animal origin to treat different types of cancer. Superoxide dismutase (SOD) is an enzyme important in defense of organisms against superoxide radicals and their toxic effects on the cells. This enzyme can be isolated and purified from animal or plant samples by using chromatography as a method of choice showing antimicrobial and, based on some reports, even anticancer effects. In our study we isolated SOD from marigold plant (Calendula officinalis
) by optimizing ion-exchange chromatography method. A therapeutic effect of Calendula officinalis
is already known, from a traditional medicine through the history until our modern time, where its antioxidative and antihaemorrhagic activity was proven in several studies. We tested potentially anticancer effect of SOD isolated from Calendula officinalis
on human lung carcinoma cell line, A549 cells. SOD of Calendula officinalis
inhibited the proliferation of tested cancer cells for 25-39.5%, after 48h of incubation, showing anticancer activity in vitro
. A bovine SOD that was parallel tested, as a comparison to marigold SOD, did not show any anticancer effect.
Keywords: Calendula officinalis

Estimating Route and Energy Consciousness for QoS Routing in Mobile Ad Hoc Networks
S. Sathish Kumar, Dr.P.Manimegalai and Dr.S.Karthik
The mobile ad hoc networks (MANETs) are a set of wireless dynamic nodes which forms an impermanent network without the help of any conventionally prevailing frameworks. The quality of service is a collection of service necessities required to be addressed by the network during transmitting a packet from a source to the target. The quality of service (QoS) maintenance is an intricate task with autonomous topology and constrained resources. The ultimate goal is to improve the QoS routing in MANET employing momentary sequenced routing scheme with self-remedial and better routing standards. The proposed SRBPR enhances the communication by observing the routes constantly and reorganizing the routes at the time of route availability. The performance is estimated based on evaluation between the conventional TORA and proposed a scheme in terms of diverse metrics. The proposed scheme greatly enhances the performance in terms of throughput, delays, packet losses and energy.

Gestion Des Donnees Geologiques Et Geotechniques En Milieu Urbain Application A La Ville De Casablanca (Maroc)
Ikram Loukili, Saida El Moutaki and Abdessamad Ghafiri
Pour mieux gérer le développement urbain, une étude géotechnique et géologique préalable est essentiel. Or, une telle étude induit inéluctablement des frais supplémentaires qui s’avèrent parfois très élevés et peuvent multiplier par dix le prix du projet. Le présent travail intéresse la ville de Casablanca au Maroc. Son objectif est d’explorer les caractéristiques géotechniques et géologiques du sol et de la roche en utilisant les SIG et la géostatistique. Le but étant de créer une base de données et des Cartes géotechniques, que les aménageurs et les ingénieurs BTP peuvent utiliser directement, sans pour autant effectuer des nouvelles études géotechniques, réalisant ainsi un gain considérable de temps et d’argent.
A cet effet, les cartes géologique et géotechnique ainsi qu’une série de 100 sondages de la région ont été collectés et utilisés. Ces différentes données ont permis de conclure que le proche sous sol de la zone casablancaise est constitué de limons, de calcarénites, de marnes, de graywackes et siltstones. La plus ancienne formation revient au cambrien moyen alors que la plus récente appartient à l’holocène. Les résultats géotechniques obtenus ont été insérés dans des systèmes d’informations géographiques et interpolés moyennant la géostatistique. Ceci a permis de générer deux cartes. Celle de la portance du sol et celle de la profondeur du substratum. La portance du sol de la zone étudiée est considérée comme moyenne. Elle varie entre un minimum de deux bars et un maximum de quatre bars. Le niveau du bon sol ou niveau d’implantation des fondations n’est pas assez profond il varie entre 0,8 m et 4,5 m.

K. Gumeni and K. Dhoska
The present work was undertaken in order to build up a CCPP Performance Monitoring DCS module for the CCPP of Vlore (Albania). The aim of this module is to evaluate the CCPP performance in terms of total CCPP Net Power Output and Net Heat Rate. The scope of PM is to give an overview to the user that allow to establish the quality of CCPP generation and how it varies during plant operation. The CCPP PM allows plant user to overview the quality of plant generation in terms of NPO at Step Up Transformer terminals, NHR, GT PO at GEN terminals, fuel oil mass flow rate, ST sections thermal PO, ST total PO at GEN terminals, ST efficiency. The utility of the PM is the comparison of the CCPP performance in terms of what is currently generated, what is expected as maximum performance and what is the actual plant performance status by means of a calculated parameter set that allows the operator to check and investigate the lack of performance on the plant. The measurement of process parameters used to calculate CCPP performances are taken by instrument used for normal operation; measured data are acquired to DCS.
