The role of grain boundary segregation in texture modification in mass-produced coils with high formability was investigated. In contrast to commercial Mg-3Al-1Zn (wt.%) alloy, texture weakening was observed in Mg-(1, 2, and 3)Al-1Zn-0.7Ca (wt.%) alloys sheets, which was contributed to solute segregation effect on grain boundaries. Moreover, texture weakening was more promoted by reducing Al contents in Mg-Al-Zn-Ca alloys sheets, leading to the highest index of Erichsen value of 9.1mm at room temperature.

In this study, shape analysis of barite mineral ground by various mills (ball, rod and autogenous) that are widely used in mineral processing, were achieved by the recent developed technique, namely; DIA and quantified shape differences by created different grinding in terms of the most common the shape parameters namely circularity (C) and bounding rectangle aspect ratio (BRAR). DIA results released that, ball milling produced particles with the highest BRAR and the lowest C values while the autogenous milling gave the highest C and the lowest BRAR values. Besides, these results, which were manually measured from microphotographs are in good agreement with results of previous studies performed by SEM technique. DIA can be used as a tool for the characterization of barite particles in some industries, where particular shape and morphology of barite is required such as paint, filler, and rubber industry.

In this contribution, as a response to the paper in Scripta Materialia, v.157, p.81, 2018, we show that the pseudo-binary approach for analysis of interdiffusion in multicomponent alloys has its reference value of the Manning factor (vacancy-wind factor) that is very different from true binary interdiffusion. In true binary interdiffusion, this factor is usually compared with unity. In the pseudo-binary analysis this reference value must be changed to the inverse of N1+N2, where Ni are the compositions (mole fractions), and components 1 and 2 are the atomic components that have different terminal compositions in the corresponding experiment.

Biodiesel has received increased attention due to higher cetane number, flash point, lesser exhaust emission compared to diesel fuel. Important correlation of density, viscosity and flash point with diesel fuel for spectrum blends are still lacking. Therefore, in this study, waste oil biodiesel (WOB) was procured and blended with diesel fuel (B0) at volume ratios of 25%, 50% and 75%, which are referred to as B25, B50 and B75. The important fuel properties of the biodiesel-diesel fuel blends were also analyzed and correlations were established for the WOB and B0 blends. The result obtained show that density and viscosity with flash point can be modelled with the fourth degree and second degrees equations respectively and can be useful for industrial applications of diesel and biodiesel blends.

Cloud storage provides a convenient and more storage at low cost, but data privacy is a major concept that prevents users from storing files on the cloud. One way of improving the data privacy is to encrypt the files before sending them onto the cloud and decrypt the files when they are downloaded. However, data encryption is a difficult task for the mobile devices, and data retrieval process is a complicated communication between the data user and cloud. With limited capacity and a limited battery life of mobile phones, these issues may introduce heavy overhead to computing and more power consumption for mobile device users, which makes the encrypted search over mobile cloud very difficult and as a challenge task for the user. In this paper, we have proposed, TEES, in which with more bandwidth and better energy efficient encrypted search over a mobile cloud. The proposed architecture removes the computation from mobile devices to the cloud, and hence we further can optimize the communications of the mobile clients and the cloud.

Phenalkamine is a curing agent produced by the reaction of cardanol, paraformaldehyde, and amine. It has high pH, high COD (Chemical Oxygen Demand), low BOD/COD ratio. In this study coagulation/flocculation and aerobic treatment of Fenton pre-treated Phenalkamine condensate (having COD of 1,50,000 mg/l ) was investigated.The optimum operating conditionin the Fenton's oxidation stage was pH-3.5, H2O2/COD ratio-1and Fe2+/H2O2 -1/30 and achieved COD removal efficiency was 80%. Fenton treated Phenalkamine condensate was subjected to coagulation-flocculation (CF) by using different coagulants like alum, ferrous sulphate, ferric chloride and polyacrylamide (anionic polymer) and the removal of COD at optimum dose of alum (200 mg/L), ferrous sulphate(200 mg/L), ferric chloride(300 mg/L) and polyacrylamide(150 mg/L), were 43.40%, 32.35%, 35.29% and 47.05% respectively. Fenton treated Phenalkamine condensate was diluted and fed toaerobic reactors operated under different hydraulic retention time (HRT-2d,5d,10d) with 3500 mg/l MLSS (Mixed Liquor Suspended Solids). 10 d HRT was found to be suitable for the treatment and the average COD removal efficiency was 75%. Fenton’s oxidation followed by coagulation/flocculation or aerobic treatmentis a feasible treatment technique for Phenalkamine condensate

Abstract In 2017 and 2018, Technology Centre Mongstad (TCM) performed long-term testing of CO2 capture with aqueous monoethanolamine (MEA) solvent through a series of test campaigns. As part of the test campaigns, a selection of materials was assessed for the CO2-MEA process by investigation and analysis of material test coupons. The test coupons were exposed to various operating conditions at five different locations in the plant. Both metal and rubber materials were tested in order to detect possible material compatibility issues with the CO2-MEA process. All metals proved to be suitable, except CS235 which in general showed severe corrosion rates exposed to the MEA solvent. However, a mid-campaign weight loss analysis indicated that CS235 might be acceptable for specific process conditions on the cold rich solvent location. No significant changes were observed on the tested rubber materials, however minor changes in hardness and tensile properties indicated some impact by the MEA solvent environment. In addition to examination of test coupons, the solvent was frequently monitored for typical factors that might indicate or influence corrosion such as the concentration of dissolved metals and heat stable salts (HSS). Some variability in average metal dissolution was observed between specific operational phases, however, the flue gas source did not seem to have significant effect on metal dissolution.

This work is a numerical simulation of pulsed flow in an adiabatic vertical parallel plate channel with four discrete heat sources on one wall of the channel and subjected to a sinusoidal profile velocity at the inlet. The finite volume method was used to solve governing equations using open source OpenFoam free code. The effects of certain topical parameters such as pulsation amplitude and frequency and Richardson number are studied. The results reveal the flow behaviour and temperature distribution are strongly affected by the pulsation of the velocity at the inlet and the rate of heat transfer during a pulsation cycle increases considerably by increasing the pulsation amplitude.
