Now a days major people used four wheeler for their comfort and Sophistication. Most of the drivers didn’t check the tire pressure regularly. Driven time observation that shows that a drop in tire pressure by just a few psi can result in the reduction of mileage, their life, safety, and vehicle performance. So we have designed to an automatic tire inflation and deflation system its continuously monitored air pressure inside the tire while running condition. When the air pressure will be over inflated or under inflation at that point the electronic system is activated to the solenoid valve. The solenoid valve is to be deplete or reload the exact air pressure. This paper will focuses to overcome the problems and suggested a proposed working model with expected results of exact maintenance of the pressure in the tyre.

Global warming and environment destruction have become the major issue in recent years. Emission of greenhouse gases from industries has impact on climate change. Preventing the depletion of natural resources and enhancing the usage of waste materials has become a challenge to the scientists and engineers. A number of studies have been conducted concerning the protection of natural resources, prevention of environmental pollution and contribution to the economy by using this waste material. Steel slag is an industrial by-product obtained from the steel manufacturing industry. This steel slag damages and affects the environment and it is difficult to decompose. If this product is used in the concrete, it influences both the mechanical and physical properties of concrete along with its durability. Walnut shell is lingo cellulosic material forming the thin endocarp or husk of the walnut shell fruit. It is very hard and takes years and years to decompose or breakdown. To solve the problem in effective manner steel slag and walnut shell is used in concrete by replacing natural aggregates. In this study, the replacement was done with fine aggregate by steel slag for different proportions of 0%, 10%, 20%, 30%, 40%&50% and coarse aggregate by walnut shell at constant proportion of 20%. M30 grade of concrete is used for a water cement ratio of 0.45. Seven mixes were prepared by partially replacing Steel Slag as fine aggregate and Walnut Shell as coarse aggregate and tested for mechanical properties such as Compressive Strength, split tensile strength and flexural strength and durability properties such as water absorption, acid attack and sulphate attack and the results were discussed elaborately.

Supplementary cementitious materials (SCM) are becoming popular in the construction industry as these materials are bringing technical revolution in the field of civil engineering. Alccofine is a new generation micro fine concrete material for high Strength Concrete which is important in respect of workability as well as strength. The aim of this paper is to highlight the importance of Alccofine as Supplementary cementitious materials in construction industries. Because of the demands in the construction industry, the necessity of high performance concrete is also increased. Over the past few years, the efforts which are made for improving the performance of concrete suggest that cement replacement materials along with the minerals and chemical admixtures can improve the strength and durability characteristics of concrete. For high strength, Alccofine is a new generation micro fine concrete material and which is important in respect of workability as well as strength. The advantage of Alccofine other than strength is that it also lowers the water/binder ratio. The fine aggregate is replaced by iron powder from iron wastes. The design mix executed for this project is M30grade concrete. The cement is replaced by 10% by Alccofine and fine aggregate is replaced by 5%,10%,15%,20% Iron powder. The compressive strength and split tensile strength were carried out with different proportioned Iron powder at different curing days for 7,14,28 days. The strength obtained from the Alccofine and iron powder concrete is compared with the conventional concrete.The durability test were conduct using Na2SO4 and HCl at 28 day curing.

The present work has enabled to aspire the enhancement of palm biodiesel viability for compression ignition (CI) engine applications using reformulation strategy by the addition of higher alcohols. In this work, 20% and 30% of 1-decanol and n-hexanol were used for ternary blend preparation along with palm biodiesel concentration as 20–30% and 50% diesel fuels for combustion, emission, and performance behaviour investigation in CI engine. Furthermore, the experimental results were also compared with 100% palm biodiesel (P100) and pure diesel (D100) and a binary blend of D50B50 fuels. The experimental study has revealed that the presence of higher alcohols in the ternary blends has improved the cylinder pressure and heat release rate whereas the same trend was not evident in binary biodiesel blend. All the ternary blends of higher alcohols-biodiesel and diesels have shown higher brake thermal efficiency and reduction in brake-specific fuel consumption. At the same time, decanol and hexanol addition in the palm biodiesel-diesel blends has favoured in all exhaust emission reductions with slight exemption in NO emission. The experimental results are optimized through multivariate and desirability analyses for identifying the effective composition of blend. Multivariate analysis has revealed that the higher alcohol proposition in the ternary blend was more influential than the type of higher alcohol. Furthermore, the desirability study has also validated the prescribed proportion with the maximum error of 6.17% for D50P22DC28 and 4.84% for D50P26HE24. Finally, the research concludes that decanol would be the preferable choice for ternary blend preparation than hexanol due to its overall better performance. x

A new molecular adduct namely, 4-(dimethylamino)benzaldehyde 4-nitrophenol (4DMAB4NP), has been synthesized through crystal engineering route by reacting 4-(dimethylamino)benzaldehyde and 4-nitrophenol in equimolar ratio. This hydrogen bonded material is found to have crystallized with centrosymmetric space group of P21/c at room temperature (RT) and making it appropriate for third order nonlinear optical (TONLO) applications. The different kinds of functional groups existing in the 4DMAB4NP were recorded and assigned through FTIR and NMR spectral studies. Thermal behavior of 4DMAB4NP was analyzed through TGA and DTA analyses. Its solubility in toluene solvent was measured to obtain high quality single crystals. The 4DMAB4NP single crystals were characterized for their laser damage threshold, TONLO properties and optical limiting behavior. Further, the dielectric behavior of 4DMAB4NP single crystal were also investigated as a function of temperature (313–343 K). In addition, density functional studies of 4DMAB4NP molecule in gaseous phase were accomplished at the B3LYP/6–311++G (d, p) basis function. Finally, 3-D Hirshfeld surface maps and the 2-D fingerprint diagram were generated for the title molecule by using crystal explorer 3.1 program.

Saphenous vein graft (SVG) bypass of the renal artery from the aorta has been well documented, though bypass of the internal iliac artery to the individual renal arteries is not yet described. We herewith present a case of early TRAS detected 6 hours after a successful renal transplant. Renal angiography showed complete stenosis of the internal iliac to renal artery anastomosis. Percutaneous transplant artery angioplasty was attempted, but was not successful; hence the surgical correction of the same was done. This is to demonstrate the use of saphenous vein bypass of anastomotic obstruction of the previous anastomosis, in case of short renal artery.

Isothermal solvent evaporation method was employed to grow Undeuterated Hydrazonium L-tartrate (HLT) single crystals using water:methanol (5:1) solution as a solvent. The proton and carbon positions of HLT have been revealed by 1H and 13C NMR spectrum, respectively. The energy emission behaviour of HLT were analysed by photoluminescence spectrum. The nonlinear refractive index (n2), nonlinear absorption coefficient (β) and third order nonlinear susceptibility (χ 3) of HLT single crystal were determined by adapting Z-scan technique. Quantum chemical calculations on HLT was carried out by DFT using B3LYP/6-311++G(d,p) basis set. The predicted first hyperpolarizability of HLT is found to be 1.09 times greater than that of urea and suggests that HLT could be an attractive material for NLO applications. The predicted HOMO-LUMO energies of HLT confirmed that charge transfers occur within the molecule. The molecular bond strength and stability of the title compound were analysed by employing NBO analysis. The other molecular properties such as Mulliken atomic charge, ESP map, thermodynamic functions and perturbation theory energy have also been investigated. These investigations have been carried out for the first time, to the best our knowledge, in order to study the nonlinear optical properties of HLT and to enhance its usefulness for NLO applications.

Nanorod films of cobalt oxide (Co3O4) have been grown by a unique oblique angle deposition (OAD) technique in an e-beam evaporator for supercapacitor electrode applications. This technique offers a non-chemical route to achieve large aspect ratio nanorods. The fabricated electrodes at OAD 80° exhibited a specific capacitance of 2875 F/g. The electrochemically active surface area was 1397 cm−2, estimated from the non-Faradaic capacitive current region. Peak energy and power densities obtained for Co3O4 nanorods were 57.7 Wh/Kg and 9.5 kW/kg, respectively. The Co3O4 nanorod electrode showed a good endurance of 2000 charge-discharge cycles with 62% retention. The OAD approach for fabricating supercapacitor nanostructured electrodes can be exploited for the fabrication of a broad range of metal oxide materials.

We report on the studies performed on Morpholinium 2-chloro-4-nitrobenzoate (M2C4N), a second order nonlinear optical (NLO) material, which has been proved to crystallize with chiral structure as compared to its other two variants. The synthesized powder was studied for its composition, crystalline phase and NLO efficiency and phasematchability. The solubility and the metastable zone width (MSZW) of the title compound were measured for the growth of bulk crystals of M2C4N. A smoky pattern observed in the middle region of the crystals that could prevent it from optical applications was greatly reduced, through suitable modifications in the growth process. The optical properties such as luminescence and laser damage threshold resistance were studied for the bulk crystals whereas the molecular vibrations of M2C4N were studied through Fourier transform infrared (FTIR) and FT-Raman spectral analysis using the polycrystalline powders derived from the single crystals. In addition, quantum chemical studies on M2C4N molecule were performed by using density functional theory (DFT) at the B3LYP/6-311++G (d, p) basis set. These studies showed that the M2C4N is a phasematchable NLO crystal and could be used for device fabrication.
