In order to realize the weight reduction of the carriage of heavy-duty truck, the 700 MPa hot-rolled high-strength C-Mn steel plate was successfully developed on 1750 mm hot-strip mills to replace the Q345 steel plate which was originally used for carriage. The microstructure of the plate was composed of fine-grained…
Two new nanostructures, Plate-shape Nanostructures and Chrysanthemum-shape Nanostructures of SnO 2, have been grown on single silicon substrates by Au-Ag alloying catalyst assisted carbothermal evaporation of SnO 2 and active carbon powders (thermal CVD). The morphology and structure of the prepared nanostructures are…
Chewable Tablets of Montelukast sodium were for the easily swallowable or palatable. Microcrystalline cellulose, Magnesium stearate, Croscarmellose sodium, Aspartame, Mannitol, Hydroxy Propyl Cellulose, Ferric oxide, these are the excipients which are used in the formulation in different ratio. Compatibility studies w…
Most agricultural soils contain large reserves of phosphorus (P), a considerable part of which accumulates as a consequence of regular applications of P fertilizers. However, a greater part of soil phosphorus, approximately 95–99% is present in the form of insoluble phosphates and hence cannot be utilized by the plant…
In this paper, we introduce the class of meromorphic univalent functions dened by hypergeometric function. We obtain some interesting properties like coecient inequality, distortion and growth theorems, Hadamard product(or convolution), radii of starlikeness and convexity for the functions in the class H (;;k ).
In this paper the effects of parameters of a square loop frequency selective surface to the resonance frequency is studied. Side length of the square loop, width of the conducting patch, thickness and the substrate are varied and their effects on resonance frequency evaluated via a Finite Integration Technique (FIT) b…
Described here is a T-shaped cationic siloxane incorporated in a microemulsion to provide a high silicone character material with balanced solubility and high hair substantivity. Wet and dry combability and hair feel were evaluated by panelists, while combing force measurements and differential scanning calorimetry me…
Recent investigations have demonstrated that ultra-fine grained (UFG) Al 5xxx alloys have a significant potential for industrial applications due to their enhanced mechanical and functional properties. The Al 5xxx alloys often have to undergo hot/cold rolling metalforming operations for fabrication of near-net shape p…
In this work plasmonic resonance of highly irregular aluminum nanostructures on a silicon photovoltaic substrate is investigated. These structures are inspired by natural surface structuring that occurs during the top-down aluminum induced crystallization of amorphous silicon. The computer simulations are obtained usi…
Ultrasonic pulse wave Compressive strength X–Ray Diffraction Differential Thermal Analysis Thermo Gravimetric Analysis When concrete is subjected to high temperature during fire accidents, it will undergo variation of in-situ moisture content, asymmetric distribution in-situ stresses, spalling leading to exposure of r…
This paper examines and compares the thermal stability and mechanical changes during hygrothermal weathering of cellulosic materials, like those found in heritage textile collections. The influence of fibre type and fibre content was evaluated using TGA and DTA measurements, as well as tensile tests for different natu…
The research aims to use shells powder as a filler adding to natural rubber with different amount (20,30,50,100,120,150 pphr) and observe its effect on mechanical properties of rubber which includes hardness and tensile strength . The obtained results from mechanical tests shown improved in rubber hardness after addin…
The mechanism and patterns of rapid crack propagation and branching in an amorphous polymer were studied on the fracture of flat samples of polymethylmethacrylate with an initial side notch under tension at room and low temperatures. It was established that crack branching occurs when the critical level of fracture st…
Withania somnifera roots are extensively using by the ethnic groups of Kurnool district, Andhra Pradesh, India to cure leucoderma. Biological synthesis of silver nanoparticles was carried out from root aqueous extract of Withania somnifera 10 ml root extract was mixed to 90 ml of 1 mM aqueous of Ag(NO3)2 and was heate…
The present study assesses the epilithic diatom communities in river in relation to environmental conditions. Epilithic diatoms and water samples were collected in 5 locations during summer season (May 2012). Analysed data were interpreted and the results are represented. Two statistical methods were used in this stud…
Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. Present work deals a cost effective and environment friendly technique for green synthesis of silver nanoparticles from Silver Nitrate solution by co-precipitation using the le…
Silver nano layers were deposited on glass substrates with three different 20 nm, 25 nm and 30 nm thicknesses, under HV conditions, at room temperature by Thermal evaporation method. Other deposition conditions were the same for all layers. By using spectrophotometer the Reflectance and the Transmittance of produced l…
Multi-layer ceramic capacitors (MLCC) rated to 200Vdc for use at 200 o C were developed using a high temperature C0G dielectric technology compatible with nickel electrodes. To meet the need for improved pulse detonator performance larger case size (2824 to 4540) capacitors rated to 2000Vdc at 200 o C were then develo…
higher values (106-82%) than the control (73 0 ). The linear densities of the alternative agents were higher than the control. The alkalinity and acidity (pH) of the alternative agents after the scouring process were environmentally friendly in comparison with the highly alkaline NaOH (control), thus unfriendly. The c…
A gel polymer electrolyte (GPE) based on an electrospun membrane of Poly (ethylene oxide) / Polyurethane (PEO/PU) incorporated with lithium ions was prepared and its performance in lithium batteries were studied. Blended form of PEO and PU electrospun fibrous membranes were prepared by electrospinning technique. Incor…
