Effect of silver–clay film thickness on some physical properties and permeability
In this study, the different film thicknesses of nano silver–clay films were prepared by varying volumes of the composite dispersion for casting. Effect of film thickness on thermal behavior, solid-state crystallinity, water uptake and erosion, and water vapor permeability of the nano composite films were investigated. The film thickness caused a small change in thermal behavior of the films when tested using DSC and TGA. The crystallinity of the thin films increased when compared with the thick films. Water uptake and erosion, water vapor permeation of the thick films were higher than those of the thin films. The results suggest that the evaporation rate of solvent in different volumes of the composite dispersion used in the preparation method could affect crystallinity of the film surface and film bulk of the nano composite films. This led to a change in water vapor permeability of the films.

Mechanical properties of Ag-Clay nano films
Mechanical properties of seven types of Ag - clay nano films were investigated. Elasticity of Modulus, Tensile Strength, Toughness, Elongation at break, Tear Strength and color of nano films were compared with those of the regular Low Density Poly Ethylene film. Results showed that inclusion of nano particles increased Modulus of Elasticity, Tensile Strength and Tear Strength but Elongation at break point and toughness of the films were decreased. The effect of film type on Modulus of Elasticity, Tensile Stress and Tear Strength, were significant at the 0.01 level and for Elongation at break point and toughness was significant at the 0.05 level. Investigation of film color parameters and ?E showed that the 1000 ppm nano Ag film has more color than other films. The smallest ?E was related to the control film. ?E value of the nano Ag films increased with increasing nano particle content and in nano composite films, decreased with increasing clay content. In sum, the nano film with 1000 ppm nano Ag content was the best film and control film was the worst film. In conclusion, the nano composite film (SC3) with 500 ppm nano Ag- 450 ppm nano clay content was the best film in terms of the mechanical properties.

A two-warehouse stock control model for perfect quality goods with quantity discounts
Stock control is an act of stocking goods to satisfy expected future demand. This gives rise to the problem of “how much and when to place order for new goods when stock is going down. Decision regarding the quantity ordered and the time at which it is ordered is based on minimizing an appropriate cost function to balance the total cost function resulting from overstocking or under stocking. Quantity discount stimulates the interest of the distributor to stock more goods and hence the need for additional warehouse which may increase his holding cost. This work has considered inventory using two warehouses-owners and rented warehouses. A model similar to that of Tien Yu Lin (2011) is developed. It has been shown that optimal order quality that minimizes the expected total cost is obtained. The consequence of the limit of the holding cost of the rented warehouse on the optimal order size is also given.

Ag percent effect on microstructure and tribological performance of Clay-Ag composite films
Clay–Ag composite films were based on polyethylene, 0.75 degree and master batch which were produced under the temperature 195-165 degrees Celsius, at 50rpm speed. The morphology and microstructure of the composite films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The tribological behavior was investigated by using a ball-on-disk tribometer in vacuum and in humid air. The crystalline Ag phase dispersed in amorphous Clay and the size of the crystalline Ag increased with the Ag content in the films. The mechanical and tribological properties of Clay–Ag composite films varied with the Ag content. At the content of 42 at %Ag, the composite film had the highest microhardness and elastic modulus. The amorphous Clay in the Clay–Ag 42% composite film made the main function during wear, so the film showed the lowest friction coefficient. The friction coefficients of the Clay–Ag composite films in vacuum were lower and more stable than those in humid air, but the environmental sensitivity of tribological behavior decreased obviously due to the addition of Ag in the films.

Impact of open space conversion on planned residential neighbourhood quality: the case of festac town, Lagos, Nigeria
The study used environmental, economic and social parameters to investigate the impact of open space conversion on neighbourhood quality in a planned residential estate in Nigeria. The study relied largely on primary survey to elicit information from 142 residents in the area using stratified random sampling approach. Data from existing literature were adopted in appropriate instances to enrich the study. Analysis of the data was carried out with use of several descriptive statistics (Relative Impact Index RII, Simple Frequencies, Percentages, Charts, etc) on Statistical Package for Social Sciences SPSS 17.0 version and Inferential Statistics (Multiple Regression Analysis). In addition, Contingent Appraisal Technique (WTP) was also employed in the analysis. The study showed that while increased neighbourhood noise level RII=0.758 is of the highest environmental effect, followed by increased air pollution RII=0.740, and increased neighbourhood insecurity RII=0. 706, however the residents’ WTP analysis revealed that the residents are willing to pay more for improved security WTP (RII=0.630) and sanitation WTP (RII=0.576) than any other aspects of environmental impact of open space conversion.

Thermodynamic analysis of 120 mw thermal power plant and generate correction curves for extraction line pressure drop (heater no.5) with the help of designed computer aided software
The thermal power plants are designed based on required conditions (like quality of steam, pressure and temperature of steam e.t.c.), but actually inlet conditions are not as per the design conditions. In practical situations, when power plants are installed there are lots of constraints. This tends to reduce or increase output power and heat rate of thermal power plants. These constraints are leakages, installation errors etc. So due to these conditions, the designed power and heat rate are never achieved. Due to these variations in the power output from plants, it is always a matter of disputes. So the correction curves for power and heat rate are generated for pressure drop in extraction line 5, as a parameter at different conditions. These curves indicate that if operating conditions are vary, then power output and heat rate also vary. This paper deals with the generation of the correction curves for 120 MW thermal power plant by using computer aided software for pressure drop in extraction line 5.
