Abstract: Pulmonary hypoplasia is a rare disease characterized by a defect of lung development more often unilateral. The diagnosis requires several exams to eliminate other causes of pulmonary retraction. We report two cases at the department of pneumophtisiology of the University Teaching Hospital of Point G. The first case is a young adult who was complaining of a chronic cough. Etiological investigation required several exams including spirometry and Computed tomographic scan (CT scan). After elimination of all suspected causes of pulmonary opacity, the diagnosis of pulmonary hypoplasia was retained. The second case is a 2-year-old girl who was born with congenital cardiopathy whose respiratory complications were increasing during her childhood and respiratory explorations discovered pulmonary agenesis. Pulmonary hypoplasia is rare in our medical practice, but attention must be drawn to a retractile pulmonary opacity in young age after elimination of all infectious causes in TB endemic area.

Abstract: Phlebotomus duboscqi is the principle vector of Leishmania major, the causative agent of cutaneous leishmaniasis (CL), in West Africa and is the suspected vector in Mali. Although found throughout the country the seasonality and infection prevalence of P. duboscqi has not been established in Mali. We conducted a three year study in two neighboring villages, Kemena and Sougoula, in Central Mali, an area with a leishmanin skin test positivity of up to 45%. During the first year, we evaluated the overall diversity of sand flies. Of 18,595 flies collected, 12,952 (69%) belonged to 12 species of Sergentomyia and 5,643 (31%) to two species of the genus Phlebotomus, P. duboscqi and P. rodhaini. Of those, P. duboscqi was the most abundant, representing 99% of the collected Phlebotomus species. P. duboscqi was the primary sand fly collected inside dwellings, mostly by resting site collection. The seasonality and infection prevalence of P. duboscqi was monitored over two consecutive years. P. dubsocqi were collected throughout the year. Using a quasi-Poisson model we observed a significant annual (year 1 to year 2), seasonal (monthly) and village effect (Kemena versus Sougoula) on the number of collected P. duboscqi. The significant seasonal effect of the quasi-Poisson model reflects two seasonal collection peaks in May-July and October-November. The infection status of pooled P. duboscqi females was determined by PCR. The infection prevalence of pooled females, estimated using the maximum likelihood estimate of prevalence, was 2.7% in Kemena and Sougoula. Based on the PCR product size, L. major was identified as the only species found in flies from the two villages. This was confirmed by sequence alignment of a subset of PCR products from infected flies to known Leishmania species, incriminating P. duboscqi as the vector of CL in Mali.

Health (Health) , 2012, DOI: 10.4236/health.2012.43020
Abstract: The aim of this research was to investigate conduct disorder among pupils of primary schools in Khartoum, the capital of Sudan. School survey descriptive method was used and 384 pupils were selected from primary schools through systematic sampling technique. Age ranged from 5 to 17 years old with a mean of (9.34) years. The tools of data collection consisted of the Sutter-Eyberg Student Behavior Inventory. The statis-tical tests used to analyze the collected data involve frequency and percentage, Pearson co-efficient of correlation, mean, t-test for one sample and t-test for two independent samples. The results of this research revealed that that the prevalence of conduct disorder among pupils of primary schools in Khartoum was low. There were significant differences in conduct disorder between male and females pupils. There were no significant differences between pupils of pre-paratory classes and pupils of elementary classes. There was no significant correlation between conduct disorder and age.
Periodicity and Solution of Rational Recurrence Relation of Order Six  [PDF]
Tarek F. Ibrahim Ibrahim
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.37107
Abstract: Difference equations or discrete dynamical systems is diverse field whose impact almost every branch of pure and ap- plied mathematics. Every dynamical system an+1=f(an) determines a difference equation and vise versa. We ob-tain in this paper the solution and periodicity of the following difference equation. xn+1=(xnxn-2xn-4)/(xn-1xn-3xn-5, (1) n=0,1,... where the initial conditions x-5,x-4,x-3,x-2,x-1 and x0 are arbitrary real numbers with x-1,x-3 and x-5 not equal to be zero. On the other hand, we will study the local stability of the solutions of Equation (1). Moreover, we give graphically the behavior of some numerical examples for this difference equation with some initial conditions.

Open Journal of Medical Psychology (OJMP) , 2012, DOI: 10.4236/ojmp.2012.13003
Abstract: This research was conducted to examine the relationship between stress and psychosomatic complaints among nurses in Tabarjal hospital. To achieve this aim, the researcher used the descriptive method and selected a sample consisting of (56) nurses working in hospital through the simple random sampling technique. The respondents were requested to complete a questionnaire for rating of stress and the most common psychosomatic diseases. The collected data were analyzed statistically by using SPSS. The results revealed that the stress was dominant among nurses in Tabarjal hospital, the prevalence of psychosomatic complaints was significantly higher in nurses, and there was significant correlation between stress and psychosomatic complaints among nurses. Conclusion: This research confirmed the effect of strains on the prevalence of psychosomatic symptoms among nurses in Tabarjal hospital. Further, implications of the results were discussed on the light of some related researches.

A. Ibrahim
Smart Grid and Renewable Energy (SGRE) , 2011, DOI: 10.4236/sgre.2011.22020
Abstract: The electrical performance of a photovoltaic (PV) silicon solar cell is described by its current–voltage (I–V) character-istic curve, which is in turn determined by device and material properties. In this study, an investigation of the performance and device parameters of photovoltaic single crystalline silicon (Si.) solar cell of the construction n+pp++ PESC(Passivatted Emitter Solar Cell) at different conditions of solar irradiance, title angle and mirror boosting effects had been studied. Also the paper reports on the performance data of the Si. cell, using standard I–V characteristic curves to obtain output parameters and to show that there are possible performance degrading defects presents.
The Influence of Memetic Primers in Online Comments in Video Game Blogs  [PDF]
Ibrahim Yucel
Advances in Internet of Things (AIT) , 2012, DOI: 10.4236/ait.2012.23008
Abstract: Through investigating a particular blog, several factors were found which have significant influence on reader actions. This study uses the term “memetic primers” for those styles that most often cause readers to take notice of a particular comment, remember information included in it, and take action. The memetic primers were derived in a discourse analysis. The study discovered the memetic primers using logic-of-inquire approach to the online comments. While evidence indicated that the usefulness of some primers was low, it emerged those negatively written comments where the most common impact on a comment’s volume.
Localisation Inverse Problem and Dirichlet-to-Neumann Operator for Absorbing Laplacian Transport  [PDF]
Ibrahim Baydoun
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.46106
Abstract:

We study Laplacian transport by the Dirichlet-to-Neumann formalism in isotropic media (γ = I). Our main results concern the solution of the localisation inverse problem of absorbing domains and its relative Dirichlet-to-Neumann operator \"\" . In this paper, we define explicitly operator \"\", and we show that Green-Ostrogradski theorem is adopted to this type of problem in three dimensional case.

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.45080
Abstract:

We study the localisation inverse problem corresponding to Laplacian transport of absorbing cell. Our main goal is to find sufficient Dirichelet-to-Neumann conditions insuring that this inverse problem is uniquely soluble. In this paper, we show that the conformal mapping technique is adopted to this type of problem in the two dimensional case.

Beginning Readers in Arabic and the Distance between Literary and Spoken Arabic  [PDF]

Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.45046
Abstract:

Two groups of kindergarten children received a battery of phonological awareness, reading, and general abilities tests across a two-year period. One of the groups received phonological training whereas the other (control) group did not. Results indicated that children who received intervention improved in certain phonological awareness skills tested at the end of kindergarten but not in reading skills tested at the end of 1st year. These findings are in contrast to findings compared to those found by Carlisle (1995) and Lyster (2002) in English, but were in line with the findings found by Ibrahim et al. (2007) in Arabic and support the notion that normal Arab child encounters special difficulties in reading acquisition. The psycholinguistic basis and implications of these findings are discussed.
