The solid phase FTIR and FT-Raman spectra of 4-chloro-2, 6-dibromoaniline (CDBA) have been recorded in the region 4000-400 cm-1 and 3500-100 cm-1, respectively. The spectra were interpreted with the aid of normal coordinate analysis following a full structure optimization and force field calculation based on the density functional theory (DFT) using the standard HF/6-31+G(d,p) and B3LYP/6-31+G(d,p) methods and basis set combination. A close agreement between the observed and calculated frequencies by refinement of the scale factor. The values of electric dipole moment (? and First-order hyperpolarizability(?) of the compound were computed using ab-initio quantum mechanical calculations.The calculation results also show that the PFA molecule might have microscopic nonlinear optical (NLO) behavior with non-zero values. HOMO and LUMO energy gap explains the eventual charge transfer interaction taking place within the molecule.

In this paper, the authors propose a voter-customer brand loyalty model using a mixture of associative network memory model, brand signalling theory and social identity theory. The model will describe the behavioural influences of the political celebrity credibility, the political party brand credibility and the political party brand image on the brand equity of the party presidential candidate, voter-customer-party identification and the voter-customers loyalty. In this model, the authors propose that credible political celebrity endorsement can effectively enhance the brand equity of the party presidential candidate and the brand credibility of the party. In addition, the brand credibility of the party may enhance the brand equity of presidential candidate. In sum, the model framework will show that the use of credible endorsers and investment on the enhancement of the party brand image will lead to enhanced brand equity and committed meaningful relationship with the party presidential candidate by voter-customers.

Mullerian abnormalities are made of a group of different congenital anomalies of the female genital system. The aim of this article is to juxtapose the normal development of the uterus with the abnormal development so a clear understanding of the cause of congenital anomalies of the uterus can be generated and correlated with the clinical significance.

Double aortic arch is class of congenital anomalies caused by a chromosome band 22q11 deletion, which are often referred to CATCH-22 syndrome or chromosome band 22q11 deletion syndrome using the unified terms. it is responsible for formation of Double aortic arch ,both right and left aortic arch arise from the ascending aorta common form of complete vascular ring, encircling both the esophagus and trachea are compressed by the aortic arches and their derivatives, resulting in non-cardiac morbidity. This study aimed to through an insight on the embryological basis, its clinical and surgical implications on the double arch aorta.

The purpose of this study is to compare organizational learning, organizational performance, and electronic human resource management in the water department staff of Tehran and Kermanshah provinces. Given its purpose, this study is an applied research, in which questionnaire is used to measure the variables. After measuring the content validity and reliability (the Alpha coefficient of electronic human resource management (0.7), organizational learning (0.8), and organizational performance (0.75)), the research tools were distrusted among the statistical population, i.e. the questionnaires were distributed in a sample of 240 individuals (120 persons from the staff in Tehran province and 120 persons from the staff in Kermanshah province) consisting of all experts of water department in Tehran and Kermanshah provinces. The statistical method of multivariate variance analysis (MANOVA) was used to analyze the data. The research results indicated that among all the variables and their components, there is a significant difference only in the information acquisition and creation component of organizational learning between the two groups, and there is no difference in other components. Finally, according to the results obtained, some suggestions have been presented to future researchers.

The major challenges in automatic multimodal image registration are the in consistency in intensity (or) contrast patterns and the existence of non overlapping regions between images. Also presence of high non-homogeneous image contrast makes it very difficult to compare the image contents. The proposed method is using a phase representation derived from Dual Tree Complex Wavelet Transform as similarity metric for registering multimodal images. This method uses a transformation that minimizes the residual error between phase representations of two multimodal images. Sub pixel level local optimization techniques are used to improve the stability in handling situations like small initial overlapping between images. This method has been tested on various multimodal images. This technique has better accuracy than existing registration techniques even in the presence of image non-homogeneity and inconsistency in intensity patterns.

We proposed a new status based clusterhead election algorithms for mobile ad hoc networks which are responsible for stable clusterhead election for a cluster and maintain a stable clustering by predicting staying time for a cluster and selecting an optimal clusterhead. In proposed method if there is two or more than two cluster heads are within the same radio range, initially clusterhead changes will be delayed up to delay timer. After delay timer expire if both the cluster heads are still in the same radio range, then old new clusterhead change its status from 0 to 1 and become as Clustermember within same cluster. In proposed method old clusterhead within the cluster has priority to act as clusterhead compared to other clusterhead which is coming from other cluster.

This study assessed knowledge commonly shared by postgraduate students in Obafemi Awolowo University. The study also investigated factors that influence postgraduate students’ knowledge sharing. The study was a descriptive survey design which involved the design of questionnaire which was validated by means of Cronbach’s coefficient alpha of (0.70). The questionnaires were administered on (503) postgraduate students. The findings revealed that knowledge in the areas of individual studies was the most commonly shared knowledge among the majority (92.8%). The study further revealed that of the three identified factors (individual, institution and technology factors) influencing knowledge sharing among the postgraduate students, only individual factor (? = .085, p < 0.05) was shown to significantly influence students’ knowledge sharing bahaviours. The study suggests further research in such areas as: the construction of shared knowledge in collaborative problem solving and computer-supported collaborative learning among postgraduate student in Nigeria.

In this study, an attempt has been made to investigate the health seeking behavior of the rural people of Satkhira district. A total of 135questionnaire were distributed and only 90 completed questionnaires were returned. The average income of the respondents was 4644.5 BDT; the most of the respondents had an urgent need of more health education. The monthly income of the respondents influenced major problem to take quality health care for the respondents. Finally, the paper provides some recommendations for the policy makers and planners which may help improve the health status of the day laborer class in Bangladesh.

This paper entitled A Study of Placelessness in V. S. Naipaul’s Life and Works focuses and analyzes with great sovereignty how the fire of getting a place fulgurates repeatedly in V. S. Naipaul’s own life and his works. This theme, directly or indirectly, has been smeared by him in some of his fiction and non-fiction works. The paper analyzes uselessness, rootlessness, placelessness, selflessness and unsuccessfulness of his characters. Place becomes burning issue in his own life also. In Naipaul’s works, his characters deliberately get staunch support by him as they personally feel a lack of a suitable place to affirm and confirm their presence in the mundane world. This paper is an attempt to give answer why is called Naipaul rootless despite of having his good roots not only in Trinidad but also in the other countries of the world and why his characters feel suffocation and seem taciturn. Naipaul gave vent to his accumulated anguish or grief through his characters in his works. Naipaul, a noted raconteur, to what extent remains successful in his endeavors with regard of the concept of place, is the key concept of this paper.
