Abstract
The present paper aims to analyze numerically the heat and mass transfer for laminar double-diffusive mixed convection flow in a parallel plate reactor with heat generation and chemical reaction. The reactant fluid enters from the left inlet and exits from the right outlet. All solid walls of the reactor are assumed to be thermodynamically isolated. After entering the reactor, the fluid passes four heated cylinder. Two-dimensional continuity, momentum, energy and concentration equations govern the developed mathematical model. Galerkin finite element method with triangular grid discretization system is used to solve the governing non-dimensional equations. The aim of the investigation is to illustrate the effects of the energy expelled during the reaction, on velocity, the thermal field and concentration of the heat sensitive chemical. Numerical simulations are conducted for different combinations of chemical reaction parameter and heat generation parameter. Results are presented in terms of streamlines, temperature and concentration distributions. The results reveal that the heat and mass transfer rate strongly depend on the mentioned parameter.
Contribution/ Originality
This study is one of very few studies which have investigated the heat and mass transfer in a chemical reactor using finite element method. The paper’s primary contribution is finding the effect of chemical reaction and heat generation on the flow temperature and concentration in a parallel plate reactor.

Abstract
 Gene therapy is treatment directed to curing genetic disease by introducing normal genes into the patients in order to overcome the effects of abnormal genes using technique of genetic engineering. The most radical approach involves applying this at the early stage in the embrayo, so that the new gene would be incorporated into the germ cells and hence will be inheritable.  This approach is not considered to be safe either safe or ethical because the consequences may affect the descendants of the patients. Therefore, this review throws more light on gene therapy, its application and consequences in the developing countries.  
Contribution/ Originality
This study contributes in the existing literature, in new gene therapy approach that repairs errors in messenger RNA derived from defective genes. It is now theoretically possible to cure all genetic diseases. It is now imperative that developing countries should embrace gene therapy technology.

Journal: Journal of Brain Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Methylphenidate (MPD) is one of the choices to treat attention-deficit / hyperactivity disorder (ADHD), and its mechanism of action is not clear. Concomitant behavioral and locus coeruleus (LC) neuronal activity were recorded following acute and chronic (0.6, 2.5 and 10 mg/kg) MPD in freely moving rats. The experiment last for 10 days. (1) The behavioral recording showed that acute MPD increases in locomotor activity in a dose dependent manner.  (2) The same dose of chronic MPD administration elicits in some animals behavioral sensitization and in others behavioral tolerance. (3) The majority of the LC unit responded to acute MPD exposure by increase their firing rate. (4) The baseline activity on experimental day 10 (ED 10) after six daily repetitive MPD exposure was modulated in most of the LC units. (5) More than 90% of the LC unit respond to chronic MPD exposure and the majority of them by decrease their firing rate compared to the initial MPD effect. (6) The neuronal response to acute and chronic MPD recorded from animals expressing behavioral sensitization was significant difference from the LC units recorded from animals that expressed behavioral tolerance. Results indicated that the LC neuronal activities may contribute to the expression of behavioral sensitization and tolerance induced by chronic MPD administration and suggested that it is essential to record the animal’s behavioral responses concomitantly with the LC neuronal activity events.
Contribution/ Originality
This paper is the first study which reported the acute and chronic dose response property of MPD on LC neuronal activity recorded concomitant with animal behavior. The study show neuronal activity recorded from behavioral sensitized animal response to MPD differently compare to those LC units recorded from behavioral tolerance animals.

Abstract
Working memory (WM) deficits often co-occur with, but do not define, attention deficit hyperactivity disorder (ADHD). Preclinical and neuroimaging studies show that ADHD and WM deficits are dissociated at the level of individual dopamine receptor function. We hypothesized that there would also be a pharmacological dissociation of the effects of stimulants on ADHD and WM. ADHD subjects were derived from three prospective clinical trials involving treatment with OROS methylphenidate for at least 6 weeks. Subjects were adolescents and adults with DSM-IV ADHD with systematic assessments of WM and ADHD symptoms. Cohen’s d was used to evaluate effect size between baseline and week 6 for all assessments, and Pearson correlations were used to evaluate the relationship between assessments at baseline and between change scores for assessments from baseline to week 6. Cohen’s d estimates for the Cambridge Neuropsychological Test Automated Battery spatial working memory measures differed significantly by 1.8 standard deviations (t= -10.8, df= 70, p < 0.001) and 1.9 standard deviations (t= -11.1, df= 70, p < 0.001) for the strategy and total between errors subcategories respectively. Confidence intervals did not overlap with those of the Adult ADHD Investigator Symptom Rating Scale (AISRS). A similar effect was observed for changes in AISRS and the Behavior Rating Inventory of Executive Function working memory scale where the Cohen’s d estimates differed significantly by 1.1 standard deviations (t= -2.5, df= 137, p = 0.015) and confidence intervals did not overlap. These findings provide further evidence for the dissociation between ADHD and WM deficits.
Contribution/ Originality
This study documents that responses to methylphenidate in ADHD symptoms and working are dissociated, indicating that a sizeable number of ADHD subjects may continue to struggle with residual working memory impairments despite good clinical response to methylphenidate.

Journal: Journal of Brain Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The aim of this study was to find out the suicide rate and possible factors associated with suicides in a rural area in Pondicherry. Information was collected regarding suicides within the last two years, using a pretested questionnaire by house to house survey in the study area which is a rural set up in the south Indian union territory of Pondicherry. We found that the annual average suicide rate in this village was 110.64/100,000 population which is very high compared to the national average. The majority of suicides were committed by married males (75%). Commonest age of suicide is 15-45 years (46.16%). The reasons found for suicide were family problems leading to stress 9(78.84%) and health problems 4(30.76%). The commonest mode of suicide was by hanging 6(46.15%) and least by burning 3(23.07%). Maximum suicide occurred in the month of November to December 4(36.36%). The findings imply the need for a holistic community based approach to tackle this complex issue of suicide.
Contribution/ Originality
The paper’s primary contribution is finding that the suicide rates in our study area are very high compared to the national average. The key target group for suicide prevention initiatives emerges as married, middle aged males working as a daily wage worker who have the habit of consuming alcohol.

Abstract
This research proposes an efficient model for predicting the survival rate of patients affected by lung cancer. The researchers collected data from four feature categories (population, recognition, treatment, and result) of cancer patients based on the importance of the survival of patients with lung cancer. Analyses of the predicted survival rates of the patients indicate that, among the classification algorithms, Decision Tree C5.0 results the highest accuracy. The models were created using algorithms based on the  level of death risk in five stages: six months, nine months, one year, two years, and five years. In this paper, we proposed a mechanism for feature selection. Our mechanism combines the results of some feature section algorithm. The results illustrate that out mechanism outperform other feature selection algorithms. After applying the proposed mechanism for feature selection, the accuracy of the C5.0 algorithm was equivalent to 97.93%.
Contribution/ Originality
This study proposes an Ensemble feature selection algorithm for predict survival of patients with lung cancer.

Gene Expression during the Cell Cycle: Obfuscation of Original Cell-Cycle Gene Expression Data by Normalization

Research Article
Author(s): Stephen Cooper
Journal: Journal of Cells

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Normalization of raw data on gene expression during the cell cycle obscures the original experimental data and makes it appear as if all genes have the same numerical level of cyclical expression. Results that would not support gene expression because of minimal variations thus appear, after normalization, to be stronger than they actually are. Consideration of the effect of normalization raises critical questions about many experiments on the cell cycle dependent variation of gene expression—that is, proposed cyclical changes in mRNA content—during the cell cycle. 
Contribution/ Originality
This paper demonstrates that normalization makes minimal variations appear much stronger than they are in the raw data, and thus one should be skeptical of some published results proposing cell-cycle specific gene expression.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Sports became the most interesting area of media coverage among different stream. As it has got its most important status in the world’s media to popularize the newspaper, there is a distinct lack of comparative research on the media coverage of sports. To minimize the gap, this search draws attention on sports coverage during the London Olympics, 2012 from three different newspapers of different languages. The coverages were recorded considering the preview, competition and review phases. The results show that the total coverage of the English newspaper, the Telegraph (36039 sq. cm.) was more than the other two Bengali and Hindi newspapers (9224 sq. cm. and 2599 sq. cm. respectively). The female performers got more attention (34942 sq. cm.) than the male performers (12920 sq. cm.). All the three newspapers provided maximum coverage in the competition phase rather than the other two phases. The English newspaper provided more attention in preview of the main competition also in comparison to the other two newspapers. It has concluded that the coverage of the print media depends mainly on the performance of the athletes, popularity of the performers and intensity of the competition.
Contribution/ Originality
The present study enriched the research in the area of sports journalism.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Many universities offer an abundant amount of physical activity courses designed to improve student knowledge and performance which may lead to increased fitness involvement. This study examined the effect of Sport Education model on university students’ (N = 25, 22 males, 3 females) basketball game performance and content knowledge of a physical activity course. Students were taught using either the Sport Education instructional model or a traditional method of teaching basketball. Data were collected to determine game efficiency through the examination of game statistics, offensive game performance measured by the basketball offensive game performance instrument, and content knowledge through the completion of a pre-and-post examination. Results revealed that students in the Sport Education group improved significantly in their offensive game performance and content knowledge compared to a traditional teaching model. In addition, the game efficiency of the Sport Education group did slightly improve while the students in the traditional group did experience a decrease. These findings suggest that the Sport Education model is an effective pedagogical approach for improving game performance and sport content knowledge of university students. Based on the limited amount of research on the impact of the Sport Education model with university physical activity courses, future studies should continue to examine the effectiveness of the model. 
Contribution/ Originality
This study is one of very few studies which have investigated the impact of the Sport Education model on a university physical activity course. Findings suggest that the model can have a positive effect on game performance and sport content knowledge.

Journal: Journal of Sports Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Post-exercise cold water immersion (CWI) has recently been developed and applied in professional sports. CWI has become widely accepted for use in sports and is endorsed by various organisations, such as the American College of Sports Medicine (ACSM), the International Amateur Athletic Federation (IAAF), and the National Athletic Trainers’ Association (NATA). Specific considerations on the extensive use of CWI in the field of sports, the effects of performance recovery after CWI intervention are noteworthy to be examined. This article aimed to review and summarize reports studying effects of CWI on post-exercise recovery. A comprehensive examination of literature was conducted and the decided databases were reviewed. Positive effects of post-exercise CWI on athletes’ endurance performance and perceived recovery were found. The possible reasons relate to the reduction of core temperature and blood redistribution. However, CWI effects on power related performance did not receive a consensus understanding in this review. Cryotherapy is normally used for limiting muscle damages, but post-exercise CWI on alternating blood markers for the muscle damages did not show a clear finding in this review. Particularly, Jadad score analysis in this review shows low on average (average Jadad score = 1.80±1.17) of the quality of the studies. It is necessary to reconsider the application on the previous examination. Further investigation is recommended, specifically on power related recovery and neural transmission alternations using randomized controlled trial with masking design.
Contribution/ Originality
The paper contributes the first logical analysis on assessing the quality of the studies related to post exercise cold water immersion recovery by the Jadad score analysis, which is assessed by three criteria: A) description of randomization, B) blinding, and C) withdrawals with dropout rates. This study also tried to provide the unbiased and exact findings through systematic reviews.

Abstract
Introduction: The ability to maintain one’s balance plays vital role during the activities of daily living. Efficient maintenance of body balance is determined by the number and type of stimuli providing information on a body position. The aim of this study was to analyze the ability to maintain balance in 7- to 12-year-old children. We analyzed the extent and direction of changes in balancing skills related to subject’s age and stability of a posturographic surface. Material and methods: The study included 266 children aged between 7 and 12 years. The level of static balance was determined with a posturographic method, with a child standing with the eyes open, first on a stable, and then on an unstable position. Results: The children aged between 7 and 8 years presented lower levels of static balance. The level of balancing skills turned out to be higher in the case of 9- to 12-year-old children. Reduced stability of a posturographic surface resulted in greater difficulties in maintaining balance. This change was observed regardless of a subject’s age and manifested as an increase in the area developed by the center of pressure and greater variability of both the velocity and number of sways in the sagittal and frontal plane. The change of the posturographic surface into an unstable one resulted in greater instability in both the frontal and sagittal plane. The increase in the area developed by the center of pressure reflected higher velocity and greater number of sways.
Contribution/ Originality
This study contributes in the existing literature to increased knowledge of the ability to body balance. This study uses new estimation methodology a posturographic method. This study originates new formula periodic testing more children from primary schools. This study is one of very few studies which have investigated children on a stable and on unstable surface. The paper contributes the first logical analysis between age of children and ability of balance. The paper’s primary contribution is finding that posturographic method is objective diagnostic instrument. This study documents relationships between the ability to maintain static balance, age and stability of a posturographic surface.
