Co-integration between KSE and other developed & emerging stock markets
The purpose of the study is to examine the relationship among developed and emerging stock markets of different countries. In developed countries there are four stock markets (Australia stock exchange, London Stock exchange, U.S Stock exchange and Tokyo Stock Exchange) where in developing countries (Bombay Stock Exchange, Colombo Stock Exchange and Chinghai Stock Exchange). Ten year data has been taken for the period from 2003 to 2012. Monthly data was taken and total numbers of observation are 120. Using the co-integration analysis we find out the long run relationship among these stock exchanges. Further for stationarity of data we use unit root test and then used Descriptive analysis, correlation analysis, vector error correction model, granger causality test, variance decomposition test and impulse response test is used to examine the existence of long run relationships. Data was stationary at first difference then we used co-integration technique. Analysis shows that KSE has long run association with developing as well as developed countries. There is a unidirectional causality between KSE, Colombo and BSE30 among the developing countries. This means that movement in KSE leads toward movement in Colombo and BSE30. On the other hand, variance decomposition of KSE shows that mostly variation in the return of KSE is due to its internal factors.

Culture as a competitive advantage and its impact on organizational productivity
In this competitive era culture makes a real difference, competitors can duplicate product, its specific features but its almost impossible for them to copy the cultural aspects. Culture is the invisible web that binds employee together to their organization. Most of the organizations work on developing their cultures to gain competitors edge over competitors examples are ebay, Netflix, Google, 3M, GE, Enterprise Rent-A-Car, W.L.Gore ant Toyota. The objective of this paper is to have the understanding of culture as a competitive advantage and its impact on organizational performance. Past researches shows that organizational culture has a strong and deep impact on organizational performance.

Influence of Soil Properties and Environmental Variables on Plant Communities in Lake Naivasha Drainage Basin; Kenya
The vegetation around Lake Naivasha is under great threat by the horticultural and livestock farming common in the region through irrigation practices and overgrazing. The vegetation is heterogeneous varying from aquatic plants, grassland, shrubland, woodland and a forest. The study was conducted to analyse the effect of soil properties and environmental variable on plant communities. A total of 227 plant species were collected and identified representing 65 families. Plant species were classified into five community types using Hierachical Agglomerative Clustering Technique of the Syntax computer programme. These were: Acacia brevispica - Acacia drepanolobium community, Acacia xanthophloea–Pennisetum clandestinum community, Euphorbia candelabrum-Euphorbia buseii community, Digitaria abyssnica-Eragrostis superba - Sida cuneifolia community, and Tarchonanthus camphoratus- Solanum incanum community. Soil samples collected from each sample plot were analysed for soil pH, electrical conductivity, cation exchange capacity, organic matter, sodium, potassium, calcium, magnesium, phosphorus, nitrogen and soil texture (sand, clay and silt content). Plant species diversity and richness decreased with distance from the lake as the woodlands and shrublands vegetation types near the lake had high plant species diversity than the grasslands. The results support the prediction that species diversity and richness decrease with increase in habitat degradation. Recommedations towards the conservation of plant species diversity around Lake Naivasha area are also put forward.

An n-dimensional pseudo-differential type operator involving Hankel type transformation
In this paper Bessel type differential operator and an n-dimensional pseudo-differential type operator involving the n-dimensional Hankel type transformation is defined. The symbol class is introduced. It is shown that pseudo-differential type operators associated with symbols belonging to this class are continuous linear mappings of the n-dimensional Zemanian space into itself. An integral representation for the pseudo-differential operator is obtained. By using the Hankel type convolution, it is shown that the pseudo-differential type operator satisfies a certain norm inequality.

Generalized Hardy type transformation of certain spaces of distributions
In the present paper, the classical generalized Hardy type transformation depending on three real parameters defined by where with and denote the Bessel type function of first and second kind of order respectively is extended to certain spaces of generalized functions by the kernel method in such a way that the theory of Pathak and Pandey [11] in relation with Hardy type transformation appears then as a particular case for . By interpreting the convergence in the weak distributional sense, an inversion theorem is established. The theory thus developed is applied to solve certain boundary value problems.

Analysis over Some Important Issues of English Pronunciation Instruction
Pronunciation is one of the most important skills in English language instruction because it impacts learners' communicative competence and performance. If speakers have very bad pronunciation, their speech will not be understandable to the listeners. This paper examines some of the important issues of English pronunciation instruction. The goals of this paper are to review the history of English pronunciation instruction, discuss the aim of English pronunciation instruction and explain the importance of English pronunciation instruction. The review of literature indicates that teachers should be aware of the aim and significance of pronunciation instruction and if they want to teach pronunciation well they should be taught in EFL pronunciation instruction.

Accelerated testing for long term durability of PU Foam Cored E-Glass reinforced vinyl ester sandwich composites
The prediction of long term mechanical properties of sandwich structures consisting of PU foam core and Vinyl Ester (VE) / Glass face sheet material under temperature, humidity and salt fog environment were performed by accelerated testing methodology based on the Time-Temperature superposition principle (TTSP). PU foam cored VE/ glass fibre reinforced sandwich structures with varied densities of PU foam were prepared and tested for degradation in flexurall properties at three different temperatures (30° C, 40° C, and 50° C) and RH 95% for a period of 120 days. The degradation in flexural properties such as Facing Bending Strength (FBS), Core Shear Strength (CSS) and compression properties (edgewise and flatwise strength) were studied. The master curves for FBS, CSS,ECS and FCS were constructed by using the test data obtained from the degradation studies at three different temperature conditions based on Time temperature super position principle and the acceleration factor has been determined. An effort has been made to develop methodologies for accelerated testing of sandwich structures for long term durability considering time, marine ambiance, temperature and humidity as major influencing parameters

Molecular structure and vibrational assignments of L-tyrosine: a detailed experimental and density functional theoretical study
L–tyrosine (C9H11NO3) is one of the 20 naturally occurring amino acids. L- tyrosine has been crystallized in silica gel by double diffusion technique which had rosette like shape. Crystal structure and spectral properties are analyzed using powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR) and UV-Vis transmittance studies. Optical band gap energy of L –tyrosine crystallite is estimated as 4.28 eV. In this study, the structural properties of L-tyrosine (C9 H11 NO3) have been studied using density functional theory (DFT) employing B3LYP exchange correlation. The geometry of the molecule was fully optimized at B3LYP/ 6-311G (d,p) level of theory. The optimized geometrical parameters obtained by DFT calculations are in good conformity with single crystal XRD data. The vibrational frequencies were calculated and fundamental vibrations were assigned based on the scaled theoretical wavenumbers. 1H and 13C nuclear magnetic resonance (NMR) chemical shifts of the molecule were calculated by using the gauge-invariant atomic orbital (GIAO) method. A study on the electronic properties, such as HOMO and LUMO energies were performed by using DFT approach. Finally, geometric parameters, vibrational frequencies, chemical shifts and absorption wavelengths were compared with available experimental data of the molecule. Quantum chemical parameters such as the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital energy (LUMO), energy gap (E), dipole moment (µ), electro negativity (?), chemical potential (Pi), global hardness (?), softness (?) and natural atomic charges were calculated. A good correlation was found between the theoretical data and the experimental results. The thermodynamic properties of the studied compound at room temperatures were calculated.
