Reduction of Harmonic pollution in IEEE 30 Bus System using Multi Spectral Coding
S. V. D. Anil Kumar and K. Ramesh Reddy
A spectral coding for harmonic suppression is presented in this paper. To achieve a harmonic suppression in spectral domain wavelet based coding were used. Such coding extracts the frequency content and performs the suppression based on spectral subtraction approach. This approach is developed based on the measured harmonic order. This approach of suppression does not focus on the density of variation among the frequency bands. This effect results in residual of harmonics in filtered signal. In this paper a modified approach to the convention DWT based coding using spectral Distortion filtration (SDF) is proposed. The comparative evaluation illustrates an improvement in the harmonic suppression using the proposed approach.

A New Approach to Interval Transportation Problems
G. Ramesh and K. Ganesan
In this paper, we focus on the solution procedure of the fully interval transportation problem (FITP) where the cost coefficients of the objective function, and the source and destination parameters have been expressed as interval numbers by the decision maker. We propose a new method for the solution of fully interval transportation problem without converting them to classical transportation problem. A numerical example is provided to illustrate the solution procedure developed in this paper.

A Microarray Gene Expressions with Classification using Extreme Learning Machine
M. Yasodha and P Ponmuthuramalingam
In the present scenario, one of the dangerous diseases is Cancer. It spreads through blood or lymph to other location of the body, it is a set of cells display uncontrolled growth, attack and destroy nearby tissues, and occasionally metastasis. In cancer diagnosis and molecular biology, a utilized effective tool is DNA microarrays. The dominance of this technique is recognized, so several open doubt arise regarding proper examination of microarray data. In the field of medical sciences, multicategory cancer classification plays very important role. The need for cancer classification has become essential because the number of cancer sufferers is increasing. In this research work, to overcome problems of multicategory cancer classification an improved Extreme Learning Machine (ELM) classifier is used. It rectify problems faced by iterative learning methods such as local minima, improper learning rate and over fitting and the training completes with high speed.

Learning Experiences of Jordanian Nursing Students using Care Plan Assignments
Ra’ed M. Shudifat and Mona A. Shuriquie
This study sought to examine the experiences of second year nursing students who are using the nursing care plan as a learning tool in the clinical area of practice. A qualitative research design with focus group methodology was used to collect data from second year students who had completed a clinical course in medical and surgical nursing. Three focus group interviews were conducted with a total of 20 student participants. Data analysis was conducted using Colaizzi's steps for analysis. Three themes emerged during the interviews: the importance of the nursing care plan, its role in gaining knowledge and it role in student evaluation. Student perceptions indicate the nursing care plan is a very useful learning tool which helps translate theory into practice, provides a framework within which knowledge can be organized and implemented, helps develop critical thinking and problems solving skills, facilitates integration into the workplace, teaches professional communication in the form of documentation and aids evaluation. The written nursing care plan, although not routinely implemented by practicing nurses in Jordan, is a valuable tool in educating nursing students. Nurse educators and managers need to facilitate the implementation of the nursing process within the clinical area in Jordan.

Seroprevalence of Classical Swine Fever Antibodies in Slaughtered Pigs at Bodija Municipal Abattoir, Ibadan, South West Nigeria
Aiki-Raji C.O., Adebiyi A.I., Adeyemo I.A., Fagbohun O.A. and Oluwayelu D.O.
Classical swine fever (CSF) is a highly infectious and economically significant viral disease of domestic and wild pigs. The disease cause serious economic losses in the pig industry. It has been eradicated in developed countries such as the US. However, the status of CSF in Nigeria remains largely unknown and underreported. Serological investigation of CSF was conducted from June to August 2013 among slaughtered pigs at Bodija municipal abattoir, Ibadan, southwestern Nigeria. Sera from 364 (237 females, 127 males) pigs were screened to detect antibodies to CSF using a commercial indirect ELISA kit. The Seroprevalence of CSF was expressed as simple percentages. Our result showed an overall seroprevalence of 154(42.3%). The seroprevalence was significantly higher in females 107(45.2%) than males 47(37.0%). These findings suggest that CSF is present in slaughtered pigs at Bodija abattoir in Ibadan, Nigeria. This therefore calls for continuous monitoring of the disease among pigs in Nigeria since the presence and re-introduction of the virus can be devastating in pig herds. This will help to ascertain the actual burden and increase awareness of the disease to facilitate early detection in order to institute appropriate control measures to eradicate CSF in Nigeria.

Evaluation of Non-Radioactive Source MPFM Performance in Hassi Messaoud Field in ALGERIA
Amor Laala and Khounfais Kamel
A series of tests have been done to evaluate a non-radioactive multi-phase flow meter (MPFM) in very high GVF conditions in Hassi Messaoud field (HMD) in Algeria, the MPFM is equipped with upstream partial separator and based on vortex meter, venturi and impedance measurements. Sixteen wells were tested and the measurements were compared to three phases test separator. It has been found that the performance of the meter is strongly related with the flow patterns. For the determination of steam component, 11 wells have gas measurement outside the accepted +/- 10% accuracy band. Most wells with water content estimation of oil flow rate was outside the accepted band whereas wells without water content estimations were within the accepted +/- 10% band. For Water Cut (WC), the absolutes errors for wells with stable flow and in oil continuous phase was within the accepted +/-2% band while the meter have difficulties to achieve the measurement for well with slug regime. The effects of flow slip model, Dynamic of wells, flow regime, Impedance technology and PVT analysis on the MPFM were analysed and presented in this paper.

Effectiveness of Supplementary Probiotics in Initial Cure Rate and Prevention of Recurrence of Bacterial Vaginosis after Vaginal Clindamycin Therapy
Aparna Khan, Arindam Ghosh, Debobroto Roy, Suparna Dhara and Tapan Gangopadhyay
To investigate the effectiveness of supplementary probiotics in initial cure rate of Bacterial Vaginosis (BV) after vaginal clindamycin therapy and their role in delaying recurrence of BV. This comparative study, conducted between July 2011 to June 2012 among the married and non-pregnant patients of child bearing age from middle class society with bacterial vaginosis diagnosed by Amsel criteria. Fifty patients in each study and control groups were included. Oral probiotics (containing 109Lactobacillus rhamnosus GR-1, 109Lactobacillus reuteri RC-14) capsules twice daily for one month to the study and placebo to the control groups were given after initial vaginal clindamycin therapy. Patients were followed up at one, three and six months by Nugent scoring. After 1 month 88% in study group and 86% patients in control group had normal flora (p 0.965). After 3 months follow up 94% and 46% patients in study and control groups respectively had normal vaginal flora ( p 0.001 ). At six months 98% patients in the study group still had BV free vaginal flora in compare to 22% of control group(p 0.0003). Supplementary probiotics does not improve the efficacy of BV therapy initially but they definitely help to prolong relapse of bacterial vaginosis.

is the main vector of yellow fever and dengue. Cases of two diseases are frequently reported in Africa. In the absence of effective drugs and vaccines, management of these diseases is limited to the reduction of human vector contact by means the use of insecticides. Unfortunately, vector control programs are facing an operational challenge as mosquitoes are becoming resistant to insecticides. Susceptibility to commonly insecticides was used in Ae. aegypti
sampled at “Cité portuaire” of Treichville (Abidjan) by the standard WHO layer-traps. The resistant status was determined using WHO standard procedures. Two types of larvae were observed: the brown colored and the white ones. Mosquitoes from the two types of larvae were resistant to DDT (mortality 58.82 to 70.87%), susceptible to permethrin and showed a decrease in susceptibility to propoxur (mortality 92.96 to 96.02%). With deltamethrin, mosquitoes from brown larvae were susceptible (98% mortality) while those from white larvae showed a decrease in susceptibility (94.87%). In regard of the recent increase in yellow fever and dengue outbreaks in Abidjan, these data on the insecticides resistance of Ae. aegypti
, can be of high relevance for public health services in the setting of more effective vector control measures.

R N’Guessan, F Dick-Amon Tanoh, D.J-P. Konan, M Cardenat and V Gbonon
En Côte d’Ivoire, deux scores cliniques sont utilisés avant la réalisation du bilan paraclinique en vue d’aider à la prise en charge thérapeutique des nouveau-nés suspects d’infection bactérienne materno-fœtale. Une étude prospective menée du 2 août au 3 octobre 2007 dans le service de néonatalogie du CHU de Yopougon avait pour objectif d’évaluer la pertinence des scores cliniques existants. Les nouveau-nés présentant un facteur de risque infectieux bénéficiés de prélèvements bactériologiques périphériques et centraux. Ils ont été classés selon le Risque Infectieux Bactérien materno-fœtal (RIB.MF). Cette classification a été comparée au score infectieux (SI). La validité des scores cliniques a été évaluée par comparaison à la classification de l’ANAES. Il n’existait pas de différence significative de classement entre les deux scores cliniques (chi deux: 0.01 P=0.94). Nos résultats analytiques montrent également que le SI est sensible de l'IBMF 82,8% mais peu spécifique 19,6%. Le RIB.MF possède une VPN de 73,7%.

Proposition of a Quantified Method for the Individual Competence Assessment in Manufacturing Industry
Abdelhamid ZAKI, Bahia BENCHEKROUN, Mohammed BENBRAHIM and Jean-Pierre CAMPAGNE
Companies are in a constant search of managing their costs and optimizing the use of their means of production. This last requires a better management of both material resources and human resources including skills. Nowadays, the issue of competency is crucial in companies, especially within a changing environment with the apparition of new forms of organization and production methods. Human resources are becoming more and more managed individually. The performance to accomplish the same task by two operators having the same qualifications is variable, which introduces the concept of individual competence level. The classical scheduling models don’t usually take account of the constraints of human resources competencies, assuming them to be identical and available at any time. In this article, we propose a method that is about the practical dimension of competence which enables the evaluation of individual competence level of operators with high added value and being usable in the domain of manufacturing. The proposed method involves four stages. The first stage concerns the research of observable, tangible and quantifiable criteria revealing individual competencies. The second stage is to define a set of indicators that will reflect the real situation and inquire about the held competence on the basis of the observed results. The third stage consists in giving a judgment on the basis of a pre-established scale of competency levels and the fourth stage consists in exploiting the calculated results which reveal the actual situation in terms of individual competence level held in the company.

A Modified Flexible Data Encryption Standard Algorithm
Essam M. Ramzy Hamed and Mohammad Hosam Sedky
This paper proposed flexible, advanced DES algorithms that solve many drawbacks in the DES algorithm. First, they increase the key size to 224 bits instead of 56 bits (the main weakness of DES) that make the Brute-Force attack effect impossible or takes very large number of years for exhaustive key search. Second, they increase the block size of the plain text messages from 64 bits to be 256 bits without increasing the simulation time. Last, the most important contributions of the proposed algorithms are: 1) they change the number of rounds from fixed number in DES (16 rounds) to dynamic number (N) that will be selected as a variable input number by the user according to the data sensitivity level he wants. Therefore, N sets the sub-keys numbers to be dynamic too. This makes the brute force attack on the proposed algorithms has no effect. 2) The algorithms codes accept any language as the plain text input messages and the secret key too. They accept the plain text message and the key to be written with any language, like English, Russian, Arabic, .etc. The importance of this modification is encouraged using any language in the applications that deal with information needed to be in certain language; like the secured e-voting application.
