The infrared and Raman spectra of valine and Leucine molecules have been recorded in nujall mull in the range 4000-400 cm^-1 . Large number of bands belonging to different modes of vibration could be observed and assigned. The electronic absorption spectra of these molecules have also been measured at different pH values. It is observed that absorption peak shifts with the change in pH value of the solutions. A tentative explanation of the peak shift is given.

Firms over the years have sought for ways of marketing their products to enable them achieve their marketing objectives, including sales and profits. As a result, they have experimented with various marketing strategies over the years. All these marketing strategies have had varying degrees of success. However, until recently, trade shows, which was practiced hundreds of years ago was not part of the tools, even though it holds the key to the success of industry. Trade shows have been identified as a cost-effective tool for promoting products of all kinds and origins. Trade shows bring both sellers and buyers together under one roof to transact business. This way, firms interact with their prospective customers or dealers more directly at a relatively cheaper cost. In recent times, there has been the proliferation of trade shows in Ghana. Researchers identified potential benefits firms could derive from participating in such exhibitions as the motive behind such a move. The outcome of the research conducted has shown that indeed positive results are derived from participating in such fairs. These have been discussed thoroughly. Other issues that cropped up in the study included evaluating performance or effectiveness of participation, preparations firms made towards participating and challenges exhibitors faced during the participation of such fairs.

Adolescence, as the last developmental stepping stone to adulthood, is a period of pronounced growth and change. Alexithymia is primarily seen as a personality constructs a trait. It means difficulty to express feelings. It affects ones mental health and somatic health positively or negatively. Social support helps the person to maintain mental health. The aim of the present investigation is to study the alexithymia in relation to general health, somatic health and social support among institutionalized and non institutionalized adolescents. The sample for the study consists of 100 institutionalized and 100 non institutionalized adolescents ranging in the age of 16 to 19 years selected randomly from Punjab, Haryana and Chandigarh.  TAS-20 Hindi version used to measure alexithymia (Bagby, Parker, & Taylor, 1994), General Health Questionnaire (GHQ- 28) by Goldberg, 1978, Somatic Health Complaints by Urmila Rani Srivastava ( ) and Social Support Questionnaire by Sarason et al., 1983.  Descriptive statistics, correlation and 2X2 ANOVA (for main and interaction effect) were used. RESULTS- The calculated values show the significant association of general health with the somatic health as the values comes out to be .311 and between general health and satisfaction with social support the value found to be -.183. It was found that there was no interaction effect between alexithymia and type of stay on general health. There was significant main effect of alexithymia on GH total and SHC as the values comes out to be 0.00. The values disclosed that there was significant interaction effect of both the independent variables i.e. alexithymia and type of stay on perceived social support. The calculated F-value found to be 3.931 which is significant at 0.05 level. 

This study assessed the surface water quality of Qua Iboe River system in the coastal Niger Delta, Nigeria. A total of 7 sampling stations were selected for the study and results obtained using FAAS revealed the following mean trace element concentrations (molar): 3.65x10^–7 for Cd, 1.50x10^–7 for Pb, 3.89x10^–7 for Cr, 1.10x10^–6 for Cu, 2.50x10^–6 for Zn, 1.06x10^–6 for Ni and 9.34x10^–7 for Co. The ion association model based on Debye-Hückel theory using the llnl.dat database of the PHREEQCI computer program as well as the thermodynamic data was used for the chemical speciation studies. The distribution of solution species for the trace elements using the PHREEQCI model revealed that the predominant species in the river system was the free ions of Ni²⁺(97.6%), Co²⁺(97.7%), Zn²⁺(92.6%), Cu²⁺(70.2%), Cu⁺(81.2%) and Pb²⁺(62.0%) as well as the hydroxy species, CrOH₂⁺(58.7%) and chloride species, CdCl₂⁺(82.3%). From the model calculations, atacamite, CdCr₂O₇, CuCr₂O₇, PbHPO₄, ternorite and pyromorphite solubility showed positive values of the saturation indices (SI), indicating supersaturation which led to mineral precipitation condition of water.

A copper complex of the type [Cu(Bipy)(L-Tyr)(TU)](ClO4), where Bipy = 2,2’ Bipyridine, Tyr = L-Tyrosine and TU = Thiourea, was synthesised and characterised by elemental analysis, UV-Visible, IR, conductivity measurement and EPR studies. DNA-binding properties have been studied by electronic absorption, emission, viscosity and cyclic voltammetric methods. The results suggest that the copper(II) complex bind to DNA via different modes. Gel electrophoresis study reveals the fact that the copper(II) complex cleaves super coiled pBR 322 DNA to nicked and slight linear forms in the presence and absence of ascorbic acid. The in vitro antimicrobial study indicates that the complex has good activity against gram positive, gram negative bacteria and fungus.

In this paper the convolution product associated with the Bessel type wavelet transformation is investigated. Certain norm inequalities for the convolution product are established.

A dynamic graphical display among the set of independent variables (partial regression plot), tolerance value, variance inflation factor (VIF) and pair wise correlation matrix among the set of predictors offers a variety of measures for assessing the problem of colinearity and multicollinearity in a multiple regression diagnostics. Multicollinearity is a violation of one of the assumption of regression analysis. Many diagnostics measures have been proposed for detecting multicollinearity. A tolerance value of less than 0.10 or 0.20 which is equivalent to a VIF of 5 or 10, p value>0.05 and the pair-wise correlation showing a linear dependence of 0.90 and above. A transformation is carried out to remove the problem of multicollinearity and the removal will help to improve on the model (yi = b0 +b ₁X₁ + b₂X₂ +……+ b_kX_k, improve coefficient of determination (r²) and validate any of the assumption of regression analysis of homocesdasticity, linearity, normality and independence of the observations. Examples using stimulated small data sets illustrate this approach

Language and Culture are not separately of each other's. Over than 10 decades in the EFL classroom in many countries have been taught Cross-Cultural and also it is emphasis on familiar to culture. Therefore this study reports the effect of teaching Intercultural Competence on Cultural Awareness of EFL learners in English classroom. The data were collected from advance level based on standard Cultural awareness questionnaire to homogenized learners who are selected in both Female and Male. The range of learners who are examined 83 that taught reading text about the different and similarities of both languages in addition in their classroom to improve their cultural awareness, the resulting of this research by Cronchbach shows that it is effecting when familiarize the learners to both Persian and English language. It makes aware to some aspect of mother tongue and target language differs. The SPSS shows that the correlation coefficient between Intercultural and Cultural awareness is positive.

In order to increase the ultrasonic trapping efficiency of bioparticles, a new cylindrical acoustic cavity with a concentric stainless cylindrical steel reflector for trapping and separation of bioparticles was designed and constructed. The resonant modes in this cavity were estimated by theoretical modeling and verified experimentally. For all bioparticles under study (RBC's, yeast and E-C0li), the simulation and measurement results were well agreed. Results obtained indicated that trapping efficiency reached 94% for RBC's at ultrasound intensity of 3 w/cm2. Acoustic contrast factor changed according the density of bioparticles and suspended medium. So it is possible to separate particles with different densities.

Voltage instability is the major concern of power system stability. It is caused due to the deficit of reactive power in the system. Improving the systems voltage by increasing the reactive power handling capacity of the system by using Static VAR Compensator, during a large disturbance is the area of study. The simulations are carried out for IEEE 14 bus system by using MATLAB/PSAT software. The result shows the effectiveness of SVC to improve the voltages when connected to a system.
