Cerebral germinoma represents i0.1 to i3.4% of intracranial tumors with a clear male predominance, it is developed more particularly in the pineal region. iIt most commonly affects adolescents and young adults. This type of tumor responds highly to radio-chemo-therapy and is potentially curable after surgery.

A separation cordial labeling of graph is a bijection f from to such that each edge uv is assigned the label 1 if ) is an odd number and label 0 if is an even number. Then the number of edges labeled 0 and the number of edges labeled 1 differ by at most 1. A graph has a separation cordial labeling, then it is called separation cordial graph. Here, the bistar the splitting graphs of and , the shadow graph of and square graph of are discussed and found to be separation cordial.

Seismic wave propagation through acoustic medium allows us to understand response through a fluid saturated medium. This interaction has been described by the acoustic wave equation. In this work, the acoustic wave equation was written in coupled form and was discretized using the staggered grid finite difference (SGFD) method, which provides improved accuracy and efficiency of the numerical modeling and are naturally centered at the same point in space and time. To truncate artificial reflections from our computational boundary, we have applied the perfectly matched layer (PML) absorbing boundary condition. Our results show seismic wave propagating through a homogeneous medium and the effect of PML was clearly observed.

Participation is a phenomenon that has long been associated with the evolution of human life, but in the 1950s and 1960s, when imported programs from the West to developing was failed because of lack of people participation, regarding to this phenomenon and emphasis on its role as an agent of development was increased and after that, the foundation of development strategies, community participation approach was formed as a basic human need. Regarding to the importance of the topic in this research by using field method, techniques and survey questionnaire sought answers to this question” Social and cultural factors involved in the construction of mosques and religious site, what are people? Given the importance of social and cultural factors involved in the construction of mosques and popular religious site in this study to analyze the relationship between variables such as socio-economic status of family, religion, social trust, sex, age, and education as independent variables and relationships it was a turnout as the dependent variable. The results indicate that among all the independent variables with the dependent variable, there was a direct and significant relationship.

The decision Mechanism is the concluding phase of any decision making process. This paper discusses on the different methodologies available for implementing the decision mechanisms. The paper preambles with a brief description on set of conventional MCDM techniques like Analytical Hierarchy Process (AHP), Simple Additive weighting Method (SAW) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), Grey Rational Analysis (GRA), along with benefits and limitations of each technique. The different intelligent/soft computing techniques that are widely used in decision making processes like fuzzy logic, neural networks are discussed and finally confines the discussion is confined to the different neural network (NN) based decision support systems. The paper proposes an architecture for fuzzy neural network based call admission control decision mechanism for heterogeneous wireless networks environment.

Alkylation reactions of phenol with dimerization products of devinylated C4-fraction obtained by the pyrolysis of low-octane gasoil were studied in the presence of KU-23 catalyst. Alkylation reaction was carried out on the continuous unit. As a result of alkylation reaction, it was studied the influence of temperature, time, initial components mol ratios and catalyst amount on the yield and selectivity. From the results of the researches it’s evident that alkylation of phenol pyrolysis process with dimerization products of C4-fraction in the presence of KU-23 catalyst are carried out under the following conditions: tempe¬rature 120°C, mole ratio of phenol to the fraction - 1:2, reaction time - 5 hours and catalyst amount - 10%. In this case the yield of the target product on phenol was 80.4%, and selectivity on the target pro¬duct was 95.7%.

To exploit limited spectrum efficiently CR technology allows unlicensed users to access licensed spectrum bands. Since licensed users have priorities to use the bands, the unlicensed users need to continuously monitor the licensed user’s activities to avoid interference and collisions. To obtain reliable results of the licensed user’s activities is the main task for spectrum sensing. Based on the sensing results the unlicensed users should adapt their transmit powers and access strategies to protect the licensed communications. This paper presents a new spectrum sensing method based on Time-Frequency Analysis. Several realistic signals are taken under different noisy conditions for analysis using Frequency Slice Wavelet Transform (FSWT) to verify its superiority in spectrum sensing.

Reducing poverty has become a priority objective of any policy based on the planning of economic and social development, we will present various strategies adopted by Tunisia to fight against poverty. In analyzing the economic and social situation in Tunisia and to test the relationship between poverty and economic growth in Tunisia, that is to say, to have it was if growth benefits the poor or not.

The molecular vibrations of 1-Naphthol were investigated in polycrystalline sample, at room temperature, by FT- IR and FT-Raman spectroscopy. In parallel, ab initio and various density functional (DFT) methods were used to determine the geometrical, energetic and vibrational characteristics of 1-Naphthol. On the basis of B3LYP/6-31G* and B3LYP/6-311+G** methods and basis set combinations, a normal mode analysis was performed to assign the various fundamental frequencies according to the total energy distribution (TED). The vibrational spectra were interpreted, with the aid of normal coordinate analysis based on a scaled quantum mechanical force field. The Infrared and Raman spectra were also predicted from the calculated intensities. Comparison of simulated spectra with the experimental spectra provides important information about the ability of the computational method to describe the vibrational modes. Simulation of Infrared and Raman spectra, utilizing the results of these calculations led to excellent overall agreement with observed spectral patterns.The investigation is performed using quantum chemical calculations conducted by means of the Gaussian 98W and Guassview set of programs. Further, density functional theory (DFT) combined with quantum chemical calculations to determine the first-order hyperpolarizability.

The aim of this study is to investigate Study of effect of selected program swimming on improving performance employees in Mobarakeh steel complex. Among 62000 intermediate category employees, 30 persons were randomly selected and divided into two groups, experimental group and control. in the first stage of study , one questionnaire was made with 30 questions that measured factors of improving practical performance and relations , creativity and enforcing practical contribution and self confidence and distributed between these experimental and control group and then they were completed , after that experimental group participated regularly in practical programs of swimming for 8 weeks with sessions and every session 1 hour and 15 min and after finishing practical period , they were examined by a test data were analyzed and following results obtained. The result shows that level of improving practical performance in experimental group in last test has meaningful effect than control group. (p<0.01). It is shown that selected practices of swimming have meaningful effect on practical performance and relations, creativity and enforcing practical contribution and self confidence. (p<0.01). This study shows generally meaningful effect on performance Mobarakeh steel employees and it is necessary that spread programs are presented for all productive industries employees and finally cause to increase products both qualitatively and quantitatively.
