Object-Oriented Image Classification Method of Automatic Lineaments Extraction: Contribution to Geological Fractures of Anti-Atlas, Morocco
Mohamed Mohamed Vall, Lakhlifi Badra, Rachid El Bayad and Ali Essahlaoui
The manual faults extraction from satellite images in geology remains a subjective method. Its result depends on the experience of the analyst.
The purpose of this work is to automate the extraction of lineaments (visible linear objects), based on the object-oriented image classification method and supported by geological parameters of faults (linearity, length and alterations), in order to establish a map of automatic fracturing.
For this purpose, we have operated two Landsat 5 images free downloaded from the US Geological Survey (USGS). Their processing has allowed the extraction of lineaments map at different scales and alterations maps (oxides of iron).
Therefore, we have grouped the lineaments in an angular class of ten degrees. As well, the ends of the linear features whose proximity of less than or equal to 4km have been connected, then merged with lineaments thus obtained from the cross analysis between the iron oxide and brute lineaments. These results, together, have been faced with the geological maps published (scale; 1/200 000) and maps of regional fracturing edited by  and . This comparison confirms the automatic extraction of major faults existing at this scale.
The automatic extraction of fracturing by the object-oriented classification method, supported by geometric and geological parameters allows us to offer a significant fracturing map of the study area. Further, this method highlights other lineaments of more reduced size. This method may find direct application in mineral mining exploration to discover vein structures; sought in the Moroccan Anti-Atlas belt.

Leishmaniasis is a widespread disease, affects millions of people and may be fatal, if not treated right away. It is caused by Leishmania species parasites and transmitted to humans by a bite of infected female sand flies.
Sand flies are insects of the family Psychodidae and subfamily Phlebotominae. There are more than 800 sand fly species but only a few serve as the vectors of human leishmaniases and some viral and bacterial diseases. Up to date real database of leishmaniasis diseases not available in Yemen and no national reports of sand fly identification, this paper presents the first investigation of the sand fly fauna in a north and northwestern Yemen. This study aimed to determine the definite vector in the targets areas in order to contribute to the eradication of the disease.In this study 214 samples were collected in 2014 by CDC light trap from Sana’a (Sawan) and Hajja (Bni Kais) areas consists 58% of Phlebotomus genera and 42% of Serogontomia genera.The research focus on Phlebotomus genera only.

W. Mahfoud, H.Amrani Hassani Joutei, I.Sadaoui, N. Elgnaoui, R. Saile, M .Karkouri, H. Lebrazi Et H. Benomar
Aims: Malignant melanoma is the skin cancer with the strongest progression since 10 years. In Morocco, few epidemiological studies on melanoma are available, and its epidemiological characteristics are generally poorly studied in African populations.
Procedure: The objective of this study is to define the epidemiology of melanoma throughout an observational retrospective study over a period of 4 years (2010 to 2014), at the pathology laboratories of Pasteur Institute of Morocco and University Hospital Averroes, Casablanca. Epidemiological and clinical parameters were collected and analyzed by SPSS software.
Results: During this period, 77 cases of melanoma have been identified, they involve 45 men (58.4%) and 32 women (41.6%). The average age is 51 years. The preferred locations are worn on the head and stroke for men as for women the most common affected site was the lower limbs. 79% of cases showed a Breslow index greater than 4 mm. The nodular melanoma was the most frequent histological form observed (34%) followed by acrolentiginous melanoma.
Conclusion: Melanoma may affect any age. Its diagnosis at an invasive stage with a Breslow index often exceeding 4 mm, is the origin of its poor prognosis thus minimizing the chances of any curative treatment. An awareness for the prevention of solar risk and early signs would serve to reduce the morbidity of the disease, and to indentify and monitor the populations at-risk by the dermatologists.

The purpose of the study was to determine the effect of a cognitive-behavioural counselling programme (CBCP) on smoking behaviour in a sample of Nigerian community-dwelling youths. The study used a pretest-posttest randomized control group design. Up to 136 youths from five communities in Akwa Ibom State participated in the study and were randomized into two groups –treatment and control groups. A smoking behaviour questionnaire developed by the researchers was used for data collection. The treatment group was subjected to CBCP for six weeks while the control group only received a one-week conventional counselling. After the intervention programme, both the treatment and control groups were subjected to posttest evaluation. The hypothesis postulated in study was tested at 0.05 level of significance using repeated measure ANOVA. The results show that CBCP has strong effect on smoking behaviour among the community-dwelling youths in the treatment group when compared to those in control group. Based on the results, it was concluded that CBCP can be used to help individuals quit smoking and other problematic behaviours.
Optimal Allocation of Multiple DGs and Capacitor Banks in Distribution Network
Sarfaraz Nawaz, Ajay Bansal, and M.P. Sharma
A novel approach is proposed in this paper for optimal placement of DG and capacitor units in radial distribution system. An objective function is formulated to determine the optimal size, number and location of DG and capacitor bank for real power loss reduction and voltage profile enhancement. A new constant, Power Voltage Sensitivity Constant (PVSC), has been proposed to solve the allocation problem. The level of DG penetration is considered in a range of 0–50% of total system load. A novel index, DGPI, is also proposed which incorporates level of DG penetration and percentage reduction in real power losses. The results of the proposed technique are validated on standard IEEE 69 bus system and 130 bus real distribution system of Jamawaramgarh, Jaipur city. The obtained results are compared with latest optimization techniques to show the effectiveness and robustness of the proposed approach.

Analysis of Genetic Diversity in Tunisian Fig (Ficus carica L.) Germplasm Bank Revealed by RAPD Markers and Morphological Characters
This research was conducted to analysis genetic diversity and related relationships among 30 fig accessions with diverse geographic origin and growing under the same environmental conditions in the Tunisian ex situ fig germplasm bank established in El Gordhab, Tataouine in Southeastern of Tunisia. Accessions were characterized through the use of 11 RAPD markers and results were evaluated in conjunction with morphological characters. Result showed a total of 119 DNA fragments (loci) were amplified and 79.83 % were polymorphic. In addition, the maximum percentage of polymorphic markers was 100 % in A04 primer. The Jaccard’s similarity coefficient within each pair of accessions which produced very similar values. The genetic similarity matrix showed a maximum genetic distance value of 0.848 was registered between ‘Bither Akhal’ and ‘Bither 1’ accessions. The combination of both molecular markers and morphological had high discriminatory power to discriminate fig accessions. The genetic similarity matrix revealed that ‘Magouli 2’-‘Magouli 1’ and ‘Nasri’-‘Jemaâoui’ accessions suggesting their close relatedness. These results proved the importance of both RAPD markers and morphological traits to elucidate in part denomination problems and relationships among accessions. This study indicated that there is great genetic diversity among local fig, making them a valuable genetic source for incorporation into potential breeding programs for fig selection.

Hend A. Elsayed, Ammar A. Ali, and Shawkat K. Guirguis
In this paper, we suggested an effective method for Electrocardiogram signal compression based on General Linear Chirplet Transform with a hybrid algorithm. A pyramid structure has been created by the hybrid algorithm based on different transform decomposition on an ECG signal. This paper describes the combination of lossy technique using Set Partitioning in Hierarchical Trees algorithm and lossless technique using Lempel Ziv Welch algorithm for better compression of an ECG signal and compares the results using Huffman or Arithmetic coding. We applied three transforms with hybrid coding algorithms on different records of the MIT-BIH database. The results show the high efficiency of this method in ECG signal compression through MATLAB.
