Water Quality Index values were also computed to evaluate the pollution load of waste water. Almost all the water quality parameters of the dyeing effluents have been found to be very high and well above the permissible limit as suggested by Bureau of Indian Standards1. Effluent of dyeing samples were collected from common effluent treatment plants (CETPs) at Tiruchirapalli and analysed monthly for a period of 12 months in order to understand various physic-chemical characteristics of the water samples Ratios like Kellys2, Magnesium, Sodium Absorption and percent sodium are well above the prescribed limits for irrigation and public use. Correlation studies have been carried out by using least squares method........

The poly (ethylene-co-vinyl acetate) - is an EVA polymer produced that has an important role in the National petrochemical industry chain. Understanding the fluid dynamic behavior during processing in pots separators is of fundamental interest for operational continuity. The drag of polymer melt to the top of the vase, is a source of interest to understand the behavior of the flow inside the machine and reduce contamination. The objective of this work is to study the phenomena the fluid dynamic behavior of EVA during processing inside the separator vessel, to propose a modification of the process.

The paper is aim at the development of a computer program for free vibration analysis of an all-round clamped (i.eCCCC) rectangular thin isotropic plate. Polynomial-based shape function for a CCCC plate, was used in Ritz energy equation to formulate an equation in term of a non-dimensional parameter 'k' for calculating the fundamental natural frequency of the plate. Computer program based on the formulated equation was develop in Matlab language for calculating fundamental natural frequency of a CCCC rectangular thin isotropic plate subjected to free vibration. To validate the values of the fundamental natural frequency obtained from the program, comparison was made between the values obtained and those available in relevant existing literatures.........

This paper treats the production and performance tests of pedal operated pressed briquettes of about 220 mm x 80 mm x 67 mm using agricultural and wood wastes. The densification was achieved by using some mechanical pressure to reduce the volume of vegetable matter and its conversion to a solid form within a pedal operated briquette press designed and constructed for that purpose. The characteristics values of the briquettes such as the effects of the binder proportion in the briquette and its effects on the combustion properties were investigated using ASTME methods. The calorific value of the briquettes ranged between 11.50 MJkg-1 and 14.02 MJkg-1, making them suitable for use as supplementary fuel in small scale industries such as bakeries........

In this study, the photocatalytic degradation of textile wastewater from Gul Ahmad textile industry in Karachi, Pakistan, using TiO2 , ZnO, and H2O2as photocatalyst was investigated. The experiments were carried out at 38 oC in astirrerbath reactor by using Ultra-Violet photo oxidation process. The degradation of wastewater using TiO2 and ZnO under various pH and using TiO2 and H2O2 were examined. Titanium dioxideand zinc oxide proved to be very effective catalysts in photocatlytic degradation of real textile industrial water. The maximum decolorization achieved was 95.29% by using TiO2 and 64.41% by using ZnO at 37 oC and pH of 9, within 150minutes of irradiations. At pH of 7.3 the maximum decolorization was 90.48%.

IN Vitro Fertilization (IVF) i.e. fertilizing an oocyte with the sperm under in vitro condition is the most convincing option for treating infertility in the couples in which conception is not possible with conventional treatments. It is achieved either by co-culturing oocyte with sperms (conventional IVF) or by injecting single sperm in the cytoplasm of oocyte (Intra Cytoplasmic Sperm Injection - ICSI). The cultured embryos are then transferred from day2 to 4 (cleavage stage) or day 5 (blastocyst stage) in the uterus of the woman under treatment for implantation. The benefit of in vitro oocyte culture prior to insemination during conventional IVF has been demonstrated; however there are discrepancies about its advantage during ICSI procedure. We undertook this work to examine the effect of duration of pre-incubation on the rate of fertilization after ICSI............

In the present study, a HPLC method for determination of the preservative propionates in 7 groups of industrial bread samples is described. The separation the propionates were performed on the C18- column and Na2SO4 (8.0 mM) + H2SO4 (1.0 mM): acetonitrile (90:10, v/v %) as mobile phase. The detector wavelength was set at 210 nm. Separation of the propionates was achieved in less than 8 min. The samples first were milled and then extracted with 0.1 mol L-1 NaOH solution under ultrasonic irradiation. After centrifuge, supernatant clear solution was filtered using 0.45 μm Nylon syringe filter and 25 μL of solution was injected to HPLC loop.........

Ogee profile flood spillways equipped with radial gates are common, and accurate computation of spilled discharge through partially-opened radial gates is an important problem. A new algorithm is developed for the method given in the latest edition of the book: Design of Small Dams for computation of discharge over ogee spillways equipped with radial gates for the partial opening case. This algorithm is more efficient with less computational load than the one presented in 'Hydraulic Design Criteria, Sheets 311-1 to 311-5' by US Army Corps of Engineers which is the method by 'Design of Small Dams'..........

A method to calculate damage evolution during the life of a strand was developed in this paper. Based on simple tensile tests, it has the advantage of being time and money saving. The residual energy damage calculation was compared to the unified theory for different loading levels. The correlation between the two methods was found for a loading level of 1.49. The energy calculation method is verified comparing with another paper where the correlation was found for a loading level of 1.68 and the damage stages were the same.

This paper analyzes long and short term relationships between the components of the public debt in Lebanon by applying the cointegration analysis of monthly time series, from January 1994 to May 2014 (245 observations), according to Johansen's procedure. The Gross Local Currency Debt(GLCD) and the Foreign Currency Debt (FCD) are not cointegrated and are modeled by near-VAR (39) revealing bidirectional causality between them. The forecasts for May 2015 are respectively USD 40.16 billion and USD 27.375 billion. These results allow us to estimate 0.28% and 0.36% as monthly growth rates from May 2014 until May 2015 for GLCD and FCD respectively. The treasury bills at short and long terms (TBST, TBLT) are cointegrated (a constant in the cointegrating relationship). The same applies to treasury bills at 12, 6 and 3 months (TB12, TB6, TB3). For the systems (TBST, TBLT) and (TB12, TB6, TB3), the available forecasts for May 2015 are respectively in USD billion (0.766, 39.568) and (0.734, 0.544, 0.153)..........

Sri Lankan power sector heavily depends on the import of fossil based energy sources and major hydro power plants. Considering the fact that Sri Lanka's hydro power reserves have already been utilized, the country's power sector highly vulnerable to price fluctuations in the imported fossil energy sources. Recent wind-mapping studies claim that the country possesses several areas estimated to have good-to-excellent wind resources. However, given such a backdrop, Sri Lanka is still lacking in its capability to maximize on the real potential of wind power based electricity generation.........

Milk price to the consumer in Vietnam is considered to relatively high compared to the producer price, or compared to other agricultural goods, or compared to incomes. This study aimed to find out how the consumers behaved and reacted against the rising milk prices in Vietnam. The data came from standard questionnaires in a survey of 100 representative respondents in a case study in Long Bien district, Hanoi, Vietnam. Results showed that three factors: the average monthly income of the household, age and career of the respondents (also decision makers in milk consumption of the household) had significant influence to consumer reaction against rising milk prices. Consumers had a lower professional career, younger and lower incomes normally had stronger reaction against rising milk prices.
