Environmental production of fashion colors from natural dyes
Dyeing is one of the most delightful textile arts which are an important branch in fashion design. Natural dye is a fascinating phenomenon that enticed researchers to their chemistry and production of fantastic novel hues to explore the point that no other dyes provide a better opportunity teaching how to protect and respect the environment. In this research, silk fabric was dyed by a mixture of different percentages of...

Decomposition method for fractional partial differential equation (PDEs) using Laplace transformation
In this Paper, we propose an efficient combination for the solution of partial differential equations (PDEs). In a similar context, decomposition coupled with Laplace transform is applied to solve partial differential equations of fractional order. It is observed that the proposed technique is highly suitable for such problems. The results of the proposed scheme are highly encouraging and efficient. It is also...

Multi-objective application of granular activated carbon in the production of carbonated beverage process water and bottled water
There are number of issues in soft drink industries’ mode of GAC operation, however, this study focuses on three issues like control of regeneration breakthrough in line with Chlorine and THM breakthrough; its frequency of regeneration and finally the competitive adsorption of different THM on two different types of GAC and extrapolation of result to full scale plant. All the experiments were conducted using rapid...

Widely tunable micro electromechanical systems (MEMS)-vertical-cavity surface-emitting lasers with single transverse mode operation
In this paper, a micro electromechanical systems vertical-cavity surface-emitting laser (MEMS-VCSEL) with asymmetric double oxide aperture and highly strained GaInNAsSb quantum wells for widely tunable, single mode and high temperature operation has been investigated. The MEMS-VCSEL is based on an integrated two-chip concept which allows us to extend the single wavelength performance to a continuously tunable,...

A preliminary investigation of the signal-to-noise ratio of Toro and Nsukka stations in Nigeria
Preliminary investigation of Toro and Nsukka stations from the Nigerian National Network of Seismographic Stations (NNNSS) with respect to Signal-to-Noise-Ratios (SNR) has been performed from noise observation and numerically. The results showed that Toro has higher SNR compared to Nsukka. Six months data collected from the stations in 2012 were used for the study. Nsukka Station in the southern part of Nigeria...
