A Comparison between Premortem and Postmortem Diagnosis in Trauma Cases  [PDF]
Dua Sumeyra Demirkiran, Ibrahim Ortanca, Mustafa Sahan, Adnan Celikel, Muhammet Mustafa Arslan
Forensic Medicine and Anatomy Research (FMAR) , 2015, DOI: 10.4236/fmar.2015.34015
Abstract: This study evaluated the comparison of premortem and postmortem diagnoses of trauma cases that died during treatment and then autopsied. We had analyzed the autopsy reports of forensic deaths retrospectively which occurred between 2013 and 2014. The cases that died because of trauma and which had complete medical reports were included the study. Totally 626 cases were autopsied and 307 cases records were examined from them. The mean age was found to be 28.11. According the treatment period, it was detected that 116 (37.8%) cases died within the first 24 hours. Discrepancies between premortem and postmortem diagnoses were determined in 20.6% of cases. 5.9% had a main diagnostic discrepancy and 14.7% were of second lethal diagnoses. The discrepancies were observed mostly in the multiple injury cases. In our study, diagnostic discrepancy rate was higher in multiple injury cases especially who died by explosion. When clinicians focus on the treatment according to their main diagnosis, they overlook the fatal injuries in other parts of the body. This study shows that autopsy is the most reliable method for the confirmation of the clinical diagnosis in trauma patients. Therefore, particularly surgery physicians should compare the results of the autopsy diagnoses to their own diagnosis.

Ibrahim Abdelrahim Ibrahim Humaida
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.
Analysis of Electrical Characteristics of Photovoltaic Single Crystal Silicon Solar Cells at Outdoor Measurements  [PDF]
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

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

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]
Raphiq Ibrahim
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.45046

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.

Reading in Arabic: New Evidence for the Role of Vowel Signs  [PDF]
Raphiq Ibrahim
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.44036

The aim of this study was to examine the effect of vowelization on reading Arabic orthography. Native children speakers of Arabic were asked to read aloud words (vowelized and unvowelized) and pseudowords. The results showed that unvowelized words were read aloud more quickly and more accurately than the shallow fully vowelized Arabic words. The disadvantage of vowelized words in both speed and accuracy was therefore unexpected, and, furthermore, inconsistent with findings from several other relevant studies. The results suggested that Arab children used a different perceptual and coding strategy when the stimuli differ in their lexical feature (word vs pseudoword) and visual/orthographic feature (vowelized vs unvowelized).
