Ultrasonic technology, as an innovative technology,was used for degradation of benzene in an aqueous solution under ultrasound frequency of 20 kHz at different temperatures with initial concentration of 100 and 200 mg/L. Kinetic and thermodynamic of benzene degradation in aqueous solution were investigated. While the…
Year upon year the cost of naval corrosion has increased until it is estimated today at 4 % of the Gross National Product. An enlightened approach to materials selection, protection and corrosion control is needed to reduce this burden of wasted materials, wasted energy and wasted money. This paper have been compiled…
The inhibition behaviour of N'-(4- (dimethylamino) benzylidene)-4-hydroxybenzo hydrazide (DABBH) on the corrosion of mild steel in 0.5 M hydrochloric acid was studied by Tafel polarization technique and electrochemical impedance spectroscopy technique. The inhibition efficiency of DABBH increased with the increase in…
The ligand salicylaldazine (H 2L) was prepared by condensation of salicylaldehyde and hydrazine in (2/1) molar ratio. The synthesized ligand was investigated using different physical techniques such as infrared, Raman spectroscopy, 1 H, 13 C NMR and UV-Visible. Transition metal complexes [ML(H 2O)];M= Zn 2+ , Cd 2+ ,…
3 Abstract: The required voltage for field emission can be reduced drastically if the emitter to anode separation is reduced significantly, assisted by the usage of Single Walled Carbon Nanotubes aligned in a horizontal way on the cathode substrate. The field emitted electrons can be accelerated by an applied field pe…
In geothermal power generation which is one of the clean renewable energies without serious CO 2 emission, materials having both high strength at relatively high temperature and high corrosion resistance are used for casing pipes. For such use, the manufacturing process of large diameter - heavy wall thickness welded…
Purpose: The research purpose is to upgrade the mathematical modelling and computer simulation of quenching of steel. Design/methodology/approach: The computer simulation of steel hardening is consisted of numerical calculation of transient temperature field in process of cooling, and of numerical calculation of mecha…
The advanced construction techniques and equipments have made the construction work much easier. Although the strength and durability of the concrete structure largely depends on the properties of the concrete. The properties of the concrete can be improved by using various types of fibres. In today world there is an…
Halloysite nanotube (HNT-OH) was modified organically using N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (APTMS).This modification converts HNT-OH directly to HNT-NH2 and improves its dispersion in polar polymer matrix. We have also prepared tungsten sulphide powder and introduced it into the Poly Ether Ether Ketone…
Columns are the key load bearing elements in concrete frame structures. In this study, the effect of blast loadings occurred within the short distance was analytically examined.
Due to the rampant brittle fracture of most mild steel fasteners, an innovative hardening process of microstructure modificaton is employed on conventional mild steel to enhance its mechanical properties. The steel specimens were subjected to inter-critical austenitising heat treatment in the temperature range of 8000…
The floor is the most vulnerable to damage part of an atmospheric storage tank. At the same time, it is the most difficu lt part to inspect. In fact, on-line quantitative inspection and evaluation is not possible for most tanks. On the other ha nd, removal of such tanks from service is a major hassle for the facility…
What is sentiment analysis? The term has been around since 2000ish, and has been used to cover a variety of different phenomena: Sentiment proper Positive, negative, or neutral attitudes expressed in text: Suffice to say, Skyfall is one of the best Bonds in the 50-year history of moviedom’s most successful franchise.…
G(d,p) basis set. Then, important molecular parameters, IR frequencies, NBO and energetic results in the gas phase were extracted. The energetic results show that relative stability of enamine tautomer (versus imine tautomer) increases with the increase of ring size and calculated frequencies show that by decreasing
In this paper we propose an accelerated plane wave expansion method (PWEM) for calculation of slab photonic crystal (slab PC) modes. In this method instead of creating artificial periodicity in the direction of slab normal and solving the problem as a full 3D one, which is done in standard PWEM, we consider constant c…
The Ge0.4Te0.6 alloy has been prepared. Thin films of Ge0.4Te0.6 has been prepared via a thermal evaporation method with 4000A thickness, and rate of deposition (4.2) A/sec at pressure 2x10 -6 Torr. The A.C electrical conductivity of aGe0.4Te0.6 thin films has been studied as a function of frequency for annealing temp…
This research article reports the performances and emissions of a 12-litre LNG-diesel dual-fuelled engine when equipped with two different gas injectors. Natural gas is used as main fuel with a pilot amount of diesel for the ignition source. The main objective of this study is to replace the imported injector by the l…
The Voderberg is one of an infinite number of tiles that can be created by deforming an isosceles triangle. Analytical expressions are derived for the segment lengths and internal angles of a generalized Voderberg tile. This generalized tile has all the familiar properties of the Voderberg tile, including spiral tilin…
The photocatalytic reduction of malonic acid was carried out in presence of bismuth vanadate and visible light. The effect of various parameters like pH, concentration of malonic acid, amount of bismuth vanadate and light intensity has been studied. A tentative mechanism has been proposed for photocatalytic reduction…
