Due to the significantly greater diagnosed cases in females, direct evaluation of a male presenting with Anorexia nervosa (AN) has infrequently been evaluated in the literature. Further, the typical view of AN often limits the perspective to those who are significantly underweight. Incidence of normal weight adolescents with AN, who are malnourished are increasing in prevalence. As in all patients with ED, a comprehensive, multi-system approach is requisite in the treatment of AN-related malnutrition irrespective of BMI. In a patients, increasing skeletal muscle mass may promote even greater health improvements than simply increasing weight/ fat. Accordingly, resistance training, as a part of a treatment plan, can improve nutrient delivery and utilization, restore weight and mitigate systemic manifestations of malnutrition.

Mobile phone industry experiences one of the fastest rate in Bangladesh in South Asian region. Subscriber penetration reached 40% at the beginning of 2014 and it is expected to grow to 50% by 2020 (GSMA, 2014). Bangladesh has 9 core users of mobile phone at present out its 15 core population. When this mobile industry is booming, the safety and security issues related to the use of mobile phone become very serious concern for both users and regulators. The privacy and security issues of mobile phone users have become a major concern. This study concerns about how personal, social and economic safety and security, and privacy issues related to the misuse of mobile phone (threat, harassment and….). This study also concerns whether the crime committing has become more organized with the help of mobile technology and whether there should be a clear law to protect general people from harassment through mobile phone. The target population for his study is the students of private universities in Dhaka. The sample size is one hundred. The structured questionnaire based on Likert scale has been used to ask the respondents to indicate their agreement or disagreement on a five point scale ranging from strongly agrees. The study comes up with the findings that misuse of mobile phone (threat, harassment and …..), is a regular activity and as a result, the students do not trust the use of mobile phone anymore. Security issue could come up due to phone tapping by government, access to call list by unauthorized people, etc. Privacy issues come up from exposing the personal mobile to public, un-timely call, un-wanted call, etc. The respondents blame the government for lack of law to protect the interest of the users. A strong pro-user regulatory board is expected by them. The study also finds that the security concerns will be more significant in the coming days than before.

Aim: A mathematical approach was employed to optimize and observe the interactive effects of Random Amplified Polymorphic DNA-PCR (RAPD-PCR) master mix with a view to resolving its limited reproducibility for reliable diagnostic and biomarker discovery for Salmonella Typhi.

Methodology: A gradient PCR for RAPD primer annealing temperature was performed, and a rotatable centred central composite design (RCCCD) using Design Expert® software was used to generate 82 experiments with six replicated centre points. Master mix components optimized include concentrations of DNA template, PCR buffer, MgCl2, RAPD primer, dNTPs and Taq DNA polymerase.

Results: The result of this study showed that significant interactions that yielded higher numbers of amplified DNA bands existed between PCR buffer and MgCl2; dNTPs and MgCl2; and RAPD primer and MgCl2. Although not statistically significant, good interactive relationships that recorded higher numbers of bands were recorded between Taq with MgCl2, and between RAPD primers and dNTPs. Reproducible RAPD-PCR results were obtained following the optimization with a co-efficient of variation (CV) value of 2.19%.

Conclusion: It was concluded that stringent and interactive master mix optimization is necessary if the simplicity and cost effectiveness of RAPD-PCR is to be utilized, and RSM offers a rapid and cost effective solution to this potentially tedious task.

Across years numerous Arab regions have made substantial investments in different tourist amenity packages. These investments were made to either capture a portion of the growing tourism market or establish an image that attracted the human capital needed to advance economic development. This study analyze the factors affecting the investment of tourism in Jordan on the different dimensions of the study.

Data have been processed and analyzed through the use of “SPSS” program in order to obtain means, standard deviations, and percentages for the demographic characteristics of the sample. Moreover, analysis of variance (ANOVA) is conducted to test if there are any statistical evidences of the existence of difference between participants to the independent variables.

The subject of this study was selected for its theoretical and practical importance in the field of tourism management in general and investment of tourism in particular.

This importance arises from the factors affecting the investment of tourism in Jordan which have great effects on individual performance.

The study revealed that there are strong statistical evidences that differences exist between employees according to their qualification of the hotel managers, hotel Location, years of experience in the hotel, number of training programs attended by the manager. However, the results show that there is statistical evidence that a difference exists between. The study provided a number of recommendations to help dealing with factors affecting the investment of tourism in Jordan.

The study examined aggregated GDP time series data for the period 1991 – 2010 to analyze the contributions of each sector to Nigeria’s GDP growth; and observe deficiencies inherent in the use of Ordinary Least Square (OLS) technique in GDP studies. Secondary data was used for the study. The data was sourced from the Central bank of Nigeria (CBN), and the National Bureau of Statistics (NBS). Analysis was carried out using graphs, tables, OLS regression technique, pairwise correlation, and Generalized Ridge Regression Analysis (GRR). Findings show an increasing trend in aggregate GDP for the study period, with an average GDP growth rate of 4.98%. Severe multicolinearity was detected in the GDP time series data using OLS regression with poor relationships, and high R2 value but few significant variables. The pairwise correlation coefficients also showed the presence of moderate to severe multicollinearity in the aggregate GDP variables. As a remedial measure, Generalized Ridge Regression analysis was employed. The GRR result showed a more well behaved model compared to the OLS implying a more precise estimation of the regression coefficients for the GRR model, which show a better influence of each sector’s contribution to the GDP growth rate within the twenty-year period. Therefore, it would be more appropriate for researchers in GDP time series studies to account for the problem of multicollinearity by utilizing Ridge regression technique for estimation since all Ridge regression models give more robust estimates than the OLS models.

More than 48 million people have been affected by diarrhea and nearly 1 million people have been affected by malaria due to climatic variability in the Sylhet region from 1988-2005. Therefore, the aim of this study is to seek the impact of climate variability on human health. Two types of data including monthly climatic data for six years collected from Bangladesh Meteorological Department, Sylhet and outpatient visit data for six years from two hospitals have collected for this study.  Inferential statistics i.e. Poisson Regression is used to analyze data. The analysis has been done using STATA 12 software; temperature, rainfall, humidity are the independent variable and number of patient is dependent variable. It is found that temperature, rainfall and humidity has significance influence on diarrhea, skin disease and mental disorder. Temperature changes of one degree and rainfall changes of 1 mm may increase 2.5%, 0.19% diarrhea patient respectively. Similarly, temperature changes of one degree and humidity changes of 1% change may increase 6.2% and 2% mental disorder patient respectively. In the same way temperature changes of one degree and humidity changes of 1% change may increase 2.5% and 2% skin diseases patient respectively. The significance level of temperature, rainfall and humidity for diarrhea, skin diseases and mental disorder is 0.00. The present study finds that diarrhea, mental disorder and skin disease are influenced by climate variability and seasonal change. The impact will likely vary by region, the sensitivity of populations. Poor people are more vulnerable than rich people in case of climate change. This study also finds that the health sector has not been developed yet, and the related data is unavailable for research work. Therefore, the present study suggests that it is important to develop a database of diseases for further research.

DOI: 10.9734/JSRR/2016/26346

Our goal in this paper is to generate functions fi from a finite group G to itself such that each fi’s are morphisms. The concept of the fundamental theorem of finite Abelian group was introduced and we proved the result that if G is any finite Abelian group, then the factor group G/H with H a subgroup of G, is a finite Abelian group. Also, if G = Zr ⊗ Zs ⊗ Zt, then G ≅ Zr ⊗ Zs ⊗ Zt where r,s,t∈Z+. We finally conclude on identifying some homomorphisms and automorphisms on finite groups by listing all the possible maps from the group to itself with the help of GAP.

In this paper, we present some methods of constructing new groups from given ones. We first examined the direct product  of the finite groups Gi for n³2 and then observed that . We also established the fact that for any prime number p > 2 and any positive integer k, |U(pk)| = |U(2pk)| where U(n) is the set of all integers less than n and relatively prime to n, and finally conclude on symmetries by constructing groups and their respective subgroups, characteristics and the unique factorization of the elements.
