Strategic role of trade shows to participating firms in Ghana: a study of the twelfth [12th] Ghana international trade fair
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.

Study of alexithymia in relation to general health, somatic health and social support among institutionalized and non institutionalized adolescents
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.

Surface water quality status and chemical speciation of Qua Iboe River system, Niger-Delta, Nigeria
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.

Synthesis, Characterisation, DNA-Binding Studies and antimicrobial activity of Copper(II) Complex with 2,2’Bipyridine, L-Tyrosine and Thiourea as Ligands
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.

The detention and correction of multicollinearity effects in a multiple regression diagnostics
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 +……+ bkXk, 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

Ultrasonic Trapping of Bioparticles Using Cylindrical Cavity
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.

Willingness to pay for safe water in ejigbo local government area, osun state, Nigeria.
This study examines the willingness to pay for safe water by households in Ejigbo local government of Osun State. Eighty respondents were selected for the study. A multistage random sampling technique was used to select the respondents. The data used for this study are mainly primary data through the use of structured questionnaire administered via personal interviews emphasizing on the importance of safe water and willingness to pay for safe water among households in Ejigbo Local Government Area. Descriptive statistics such as tabula presentation, frequency distribution, cumulative percentages and mean were used to analyze the slated objectives. The Logit model was also used to test for the formulated hypothesis. The study revealed from the socio-economic characteristics that majority of the respondents is male while most of them are within their youthful age. Sixty percent are married, 55% of them have a household size of between 1 and 5. More than four-fifth (80%) of them get their water from wells and boreholes, 62.5% treat their water before consumption, 47.5% have a record of one illness or the other. Two-third (67.5%) prefer other water sources. The highest percentage of respondents (56.3%) was willing to pay for safe water. Marital status is statistically significant at 5% with a value of 2.079, these shows that marital status has a positive significance with the willingness to pay for water. Primary occupation is statistically significant at 5% with a value of -2.227, this implies that it has a negative significance with the wiliness to pay for safe water. Secondary occupation is statistically significant ay 5% with a value of -2230, this implies that it has negative significance on the willingness to pay for safe water. Age, primary occupation and secondary occupation have a negative marginal effect on the willingness to pay for safe water in the study area with a value of -2.192,-2227 and -2230 respectively. Even though significant, and increase in these three variables will not raise the morale to willingly pay for safe water. Conclusion was drawn that most of these respondents are willing to pay for safe water but a lot of factors inhibit their willingness to pay such as price, distance to the source of water supply and availability.
