Under the effect of non-geological sources such as the altitude of the stations, the effect of the sun and the moon, the effect of the surrounding topography and the instrumental drift, the measured gravity data are subject to changes in time and in space. It is necessary to evaluate and eliminate these effects in considerable precision in order to have more reliable data that can provide the most information about the subsurface structure in the Kribi-Campo sub-sedimentary basin. This study highlights that, the free-air correction and Lunisolar correction are the most prominent in this area given its geographical position, its topographic variation and the survey configuration. Dependency of the terrain correction with isostatic compensation on one hand, and plateau correction with the established tectonic activities in the survey area were also highlighted. Despite the observed insignificance of terrain correction in local scale areas with little topographic fluctuations, its application contributes however to accuracy of the analyzed data. This analysis could be used to guide the choice of gravity corrections to be applied on raw data and decipher their relationship with gravity noise and tectonic activities.

Evaluation of Different Features of Object for Human Tracking in Thermal Imaging and Visible Imaging

Mahajan J.R and C.S.Rawat
Motion Tracking has been applied in many recent applications like surveillance, ADAS etc. Current research in this field includes making system robust and reliable in human tracking. We carried out the novel evaluation process for features of human object in the thermal imaging and visible imaging. Additionally, we also compare the performance of different features of human object. The problem addressed here is to determine the best candidate for feature to be used and imaging modality to be considered in tracking algorithm. The feature continuity (FC) and discrimination capability (DC) are new performance measures, we introduced for evaluating the different features. In this work, experimental results shows the evaluation for three features of human object, namely, average intensity, n-bin intensity histogram and edge histogram using visible and thermal imaging.

Improved K-Means Clustering Algorithm to Analyze Students Performance for Placement Training using R-Tool

T.Thilagaraj and N Sengottaiyan
The Procedure of organizing all objects in particular groups through some kind of similarity among objects is clustering. The student’s placement training is necessary for their career and also for successful placement in industry. The selection of students for the training is important and group formation among them using some strategy is a difficult task. This provides a common activity for entire students that will not lead them exactly on their path. The clustering of students is needed to overcome this problem. The K-Means clustering algorithm will choose the centroid in random approach, so the clusters will differ according to the centroid value. This will not lead to the required results which is the main drawback of the K-Means clustering algorithm. So the improved K-Means clustering algorithm is proposed to cluster the student performance with initial centroid and will choose best centroid from that to provide the required clusters.

Inventaire et Prévalence des Cestodes Parasites des Anoures dans Trois Zones agro-Industrielles au Sud-Est de la Côte d’Ivoire

Oungbe Kary Venance, Kouame Kouakou Augustin, N’zi Konan Gervais,Goore-BI Gouli and N’douba Valentin
L’inventaire des Cestodes parasites des Anoures ainsi que leur degré d’infestation ont été investigués dans trois zones agro-industrielles au Sud-Est de la Côte d’Ivoire de novembre 2016 à octobre 2017. Au total, 822 spécimens dont 207 échantillonnés dans les cocoteraies, 233 dans les palmeraies et 382 dans les bananeraies ont été examinés. Ces spécimens se répartissent en 28 taxons. La dissection des Anoures collectés a permis de mettre en évidence 2 taxons de Cestodes parasites par un examen parasitologique standard. Il s’agit de Cylindrotaenia jaegerskioeldi et Proteocephalus sp. La prévalence globale d’infestation de 3,4%, montre une très faible infestation parasitaire des Anoures par les Cestodes dans les trois zones agro-industrielles. Cette infestation est influencée par la très grande sélectivité et spécificité des Cestodes. Il en ressort que sur les 28 taxons d’Anoures examinées, seulement quatre espèces (Afixalus dorsalis, Arthroleptis sp. Hyperolius guttulatus, Ptychadena longirotris) ont été infestées par les Cestodes parasites. Le site préférentiel d’infestation des Cestodes dans l’Anoure hôte est l’intestin grêle.

Effect of Sucrose and Date (Phoenix dactylifera) on Blood Sugar, Lipid Profile and Liver Function of Normal Wistar Rat

Adeoye, B. K, Babajide, T. A, Ngozi, E. O., Oyerinde, O. O., Olanrewaju, M. F.,Ani, I. F. and Olumide, M. D.
This research aimed at determining the effect of sucrose and date (Phoenix dactylifera) extract in normal male wistar rats. The date extract was processed by drying, grinding and extracting with water while table sugar was merely dissolved in water to obtain 10 °Brix respectively. Fifteen (15) male wistar rats of 9-10 weeks old were grouped into three groups of five rats per group. Group A (control) was fed regular rat feed and water, Group B was fed regular rat feed and sucrose solution, while Group C was given regular rat feed and date extract. The weight and the fasting blood sugar of the animals were taking at baseline and also weekly and every two weeks respectively. Daily food and water intake were recorded and the experiment lasted for four weeks when the plasma glucose concentration, glycosylated heamoglobin, serum lipid profile, liver function, and histopathology of the liver were determined. Feed intake of the control group was significantly higher than that of the other groups while sucrose and date extract consumption of the other two groups were significantly higher than water intake of the control group. Groups given sucrose and date extract had significant weight gain compared to the control group. Sucrose significantly increased the plasma concentration, glycosylated heamoglobin, low density lipoprotein (LDL), total cholesterol and triglyceride but decreased high density lipoprotein (HDL) of the rats. While cholesterol, HDL, LDL, and triglyceride were not significantly different for the control and the group given date extract. There was no significant difference in the aspartate aminotransferase (AST), alanine aminotransferase (ALT) and liver weight. The histopathology showed that both sucrose and date had adverse effect on the liver structure with sucrose having more pronounced effect on the liver compared to date. Date may be a better substitute to sucrose in terms of effect on blood sugar, lipid profile and histopathology of the liver.

Ezeokoli, Rita Nkiruka, Ayodele, Kolawole Olanrewaju and Akongwale, Patricia
The study assessed the knowledge and attitude of healthcare personnel on the need of palliative care services in Babcock University Teaching Hospital Ilishan, Remo Ogun State, Nigeria. Descriptive survey research design was adopted for the study. Stratified random sampling technique was used to select 100 respondents. Self-developed questionnaire tagged “knowledge; Attitude to Palliative Care Services” (KAPCS) was used to obtain information from the respondents. Four hypotheses were raised for the study. The data obtained was analyzed using descriptive statistics of frequency counts and percentages to answer the demographic information. Pearson Product Moment Correlation (PPMC) and Regression Analysis were used to test the hypotheses. Findings indicated a significant positive relationship between knowledge and attitude of healthcare personnel on palliative care (r = .0.507, P =.001). The result further showed a significant joint influence of healthcare personnel's knowledge and attitude on palliative care services (R2 = 0.184, F = 8.872, P <.05), while years of experience moderate the influence of knowledge and attitude on the need for palliative care services (f-value = 4.381, P = 0.017). No significant influence exist in the contribution of gender to the knowledge and attitude of healthcare personnel to palliative care services (f-value = 1.219, P = .923). The research concluded that, research in palliative care should be encouraged as this would help in the identification of palliative care needs in the country and subsequently improve standard of practice of the profession as well as care of the terminally ill.

DPPH Scavenging Activity of Mallotus oppositifolius: A Kinetic Study

Sylvestre Koffi Tanoh, Brice Amani Kadja, Christelle Kohué N’gaman-Kouassi, David Boa, Janat Akhanovna Mamyrbékova-Békro and Yves-Alain Békro
The kinetic behaviour of Mallotus oppositifolius leaf and root extracts (MOlE and MOrE, respectively) as free radical scavengers was studied using 2,2-diphenyl-1-picrylhydrazyl (DPPH•). The analysis of kinetic measurements was done using the bi-exponential model. Efficient concentration (EC50) and antiradical efficiency (AE) were used to evaluate antioxidant capacity. EC50 values (in µg/mL) obtained at the steady time for Quercetin, MOlE and MOrE were determined as 153.1 ± 0.2, 206.4 ± 0.2 and 301.5 ± 0.2, whereas the corresponding AE (10-6kg DPPH•/g AO.min) values were 5.6 ± 0.2, 5.8 ± 0.3 and 3.8 ± 0.2, respectively. A new antioxidant capacity parameter kEC50, taking into account the second-order rate constant (kb) and EC 50was proposed in the present work (kEC50 = kb/EC50). The results have shown that the order of the kEC50 was Quercetin > MOlE ≈ MOrE.

Formulation Galénique d’une Pommade Antimicrobienne à Base d’un Extrait Hydroalcoolique de Aspilia africana (Pers.) C.D. Adams var. Africana, une Plante de la Pharmacopée Africaine

Yapi Adon Basile, Etien Dibié Théodore, Konan Kouadio Fernique and Zirihi Guédé Noël
Dans le but de mettre au point une pommade antimicrobienne (MTA), à moindre coût, efficace et accessible à tous, nous avons entrepris une étude ethnobotanique des plantes médicinales fréquemment utilisées dans les soins de santé primaire en Afrique et commercialisées dans le District d’Abidjan (Côte d’Ivoire). Aspilia africana, appelée Zeu-nanh en Akyé et Soumadibrou en Malinké (sud et nord de la Côte d’Ivoire) a été retenue pour ses divers usages en médecine traditionnelle dont le traitement des mycoses. La formulation galénique a permis la mise au point de Aspaderm, une pommade antimicrobienne à base d’un extrait hydroéthanolique 70 % des feuilles de A. africana en utilisant comme excipient le beurre de karité. Les paramètres étudiés de la pommade, les évaluations antimicrobiennes effectuées ainsi que des tests cliniques réalisés sur trente patients volontaires atteints de diverses dermatoses ont produit des résultats satisfaisants. Aspaderm, phytomédicament amélioré a ainsi une efficacité prouvée et pourra être vendu à moindre coût par rapport aux antimicrobiens modernes.
